cf5787f2a4 pci: fix some warnings related to assumptions about
The following commit introduced some warnings associated with using
pci_addr_t instead of a proper 32-bit data type.

    pci: fix errant data types and corresponding access functions

On some platforms pci_addr_t is defined as a 64-bit data type so its not
proper to use with pci_{read,write}_config_dword.

55b523b7d4 ext4: cache-align buffers so the invalidation works
DMA buffer cache invalidation requires that buffers have cache-aligned
buffer locations and sizes. Use memalign() and ALLOC_CACHE_ALIGN_BUFFER()
to ensure this.

On Tegra at least, without this fix, the following fail commands fail in
u-boot-master/ext4, but succeeded at the branch's branch point in
u-boot/master. With this fix, the commands work again:

The defines in arch/m68k/include/coldfire/flexbus.h are not compatible with

    when NULL, no check is performed.

And a new argument to himport_r():

consecutive 16-bit registers. This patch reads all the fields of this value,
which makes a difference for 4-kiB NF pages.

9c790a748f mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver
This is based on Linux kernel -next:

commit 14f44abf1dafc20ba42ce8616a8fc8fbd1b3712b
Author: Brian Norris <computersforpeace@gmail.com>
Date:   Fri Jul 13 09:28:24 2012 -0700

    mtd: nand: allow NAND_NO_SUBPAGE_WRITE to be set from driver

    The NAND_CHIPOPTIONS_MSK has limited utility and is causing real bugs. It
    silently masks off at least one flag that might be set by the driver
    (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly
    others.

    Really, as long as driver writers exercise a small amount of care with
    NAND_* options, this mask is not necessary at all; it was only here to
    prevent certain options from accidentally being set by the driver. But the
    original thought turns out to be a bad idea occasionally. Thus, kill it.

    Note, this patch fixes some major gpmi-nand breakage.

cf46cdebdd ARM: tegra: fix Ventana standalone build
Ventana always pulls in files from the Seaboard directory, so needs to
mkdir $(obj)../seaboard unconditionally. This fixes:

git clean -f -d -x
./MAKEALL ventana

"MAKEALL -s tegra20" passes without this change, because Seaboard
happens to be built before Ventana, and hence the directory has already
been created.

I believe the mkdir is only needed for out-of-tree builds, since the
seaboard directory is part of the source tree. However, since we always
build an SPL for Tegra now, which I believe is effectively an out-of-tree
build, we will always need this at some time. The overhead of just
uncondtionally executing the mkdir is minimal, and simplifies the
Makefile, since we don't need to code up the exact minimal condition to
execute the mkdir.

573668a24e tegra: put eMMC environment into the boot sectors
When I set up Tegra's config files to put the environment into eMMC, I
assumed that CONFIG_ENV_OFFSET was a linearized address relative to the
start of the eMMC device, and spanning HW partitions boot0, boot1,
general* and the user area in order. However, it turns out that the
offset is actually relative to the beginning of the user area. Hence,
the environment block ended up in a different location to expected and
documented.

Set CONFIG_SYS_MMC_ENV_PART=2 (boot1) to solve this, and adjust
CONFIG_ENV_OFFSET to be relative to the start of boot1, not the entire
eMMC.

eMMC devices may have hardware-level partitions: 2 boot partitions,
up to 4 general partitions, plus the user area. This change introduces
optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which
partition the environment should be stored in: 0=user, 1=boot0, 2=boot1,
4..7=general0..3. This allows the environment to be kept out of the user
area, which simplifies the management of OS-/user-level (MBR/GPT)
partitions within the user area.

Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT
bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such
devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set.

Note that the Linux kernel enables access to boot partitions solely based
on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only
influences access to "general" partitions.

eMMC devices affected by this issue exist on various NVIDIA Tegra
platforms (and presumably many others too), such as Harmony (plug-in eMMC),
Seaboard, Springbank, and Whistler (plug-in eMMC).

97ed12cedf MX28: MMC: Avoid DMA DCache race condition
This patch prevents dcache-related problem. The problem manifested
itself on the SPI driver, this is just a port to the MMC driver.

The scenario is the same. In case an "mmc read" is issued to a
buffer which was written right before it and data cache is enabled,
the cache eviction might happen during the DMA transfer into the
buffer, therefore corrupting the buffer. Clear any cache lines that
might contain the buffer to prevent such issue.

e9f7eafd3c MX28: SPI: Fix the DMA chaining
It turns out that in order for the SPI DMA to properly support
continuous transfers longer than 65280 bytes, there are some very
important parts that were left out from the documentation.

Firstly, the XFER_SIZE register is not written with the whole length
of a transfer, but is written by each and every chained descriptor
with the length of the descriptors data buffer.

Next, unlike the demo code supplied by FSL, which only writes one PIO
word per descriptor, this does not apply if the descriptors are chained,
since the XFER_SIZE register must be written. Therefore, it is essential
to use four PIO words, CTRL0, CMD0, CMD1, XFER_SIZE. CMD0 and CMD1 are
written with zero, since they don't apply. The DMA programs the PIO words
in an incrementing order, so four PIO words.

Finally, unlike the demo code supplied by FSL, the SSP_CTRL0_IGNORE_CRC
must not be set during the whole transfer, but it must be set only on the
last descriptor in the chain.

88d1555968 MX28: SPI: Fix the DMA DCache race condition
This patch fixes dcache-related problem. The problem manifested
when dcache was enabled and the following command issued twice:

mw 0x42000000 0 0x4000 ; sf probe ; sf read 0x42000000 0x0 0x10000 ; sha1sum 0x42000000 0x10000

The SHA1 checksum was correct during the first call. Yet with
every subsequent call of the above command, it differed and was
wrong.

It turns out this was because of a race condition. On the first
time the command was called, no cacheline contained any data from
the destination memory location. The DMA transfered data into the
location and the cache above the location was invalidated. Then the
checksum was computed, but that meant the data were loaded into data
cache.

On any subsequent call, the DMA again transfered data into the same
destination. Yet during the transfer, some of the DCache lines were
evicted and written back into the main memory. Once the DMA transfer
completed, the data cache was invalidated over the memory location as
usual. But the data that were to be loaded back into the data cache
by subsequent SHA1 checksuming were corrupted.

1c1ec3c0b5 tegra: put eMMC environment into the boot sectors
When I set up Tegra's config files to put the environment into eMMC, I
assumed that CONFIG_ENV_OFFSET was a linearized address relative to the
start of the eMMC device, and spanning HW partitions boot0, boot1,
general* and the user area in order. However, it turns out that the
offset is actually relative to the beginning of the user area. Hence,
the environment block ended up in a different location to expected and
documented.

Set CONFIG_SYS_MMC_ENV_PART=2 (boot1) to solve this, and adjust
CONFIG_ENV_OFFSET to be relative to the start of boot1, not the entire
eMMC.

eMMC devices may have hardware-level partitions: 2 boot partitions,
up to 4 general partitions, plus the user area. This change introduces
optional config variable CONFIG_SYS_MMC_ENV_PART to indicate which
partition the environment should be stored in: 0=user, 1=boot0, 2=boot1,
4..7=general0..3. This allows the environment to be kept out of the user
area, which simplifies the management of OS-/user-level (MBR/GPT)
partitions within the user area.

Some eMMC devices contain boot partitions, but do not set the PART_SUPPORT
bit in EXT_CSD_PARTITIONING_SUPPORT. Allow partition selection on such
devices, by enabling partition switching when EXT_CSD_BOOT_MULT is set.

Note that the Linux kernel enables access to boot partitions solely based
on the value of EXT_CSD_BOOT_MULT; EXT_CSD_PARTITIONING_SUPPORT only
influences access to "general" partitions.

eMMC devices affected by this issue exist on various NVIDIA Tegra
platforms (and presumably many others too), such as Harmony (plug-in eMMC),
Seaboard, Springbank, and Whistler (plug-in eMMC).

level converter first by setting the PC9 pin to high. The level converter needs
some time to settle so we have to use the mdelay() function to wait for some

enable the serial output early within board_postclk_init().

0d7d383098 efikamx: refine USB support
Because of the way USB pad settings are handled it doesn't make sense to
be able to build the Efika MX board support without CONFIG_CMD_USB turned
on. So, we change the build to always compile in USB support.

We do not need to check for CONFIG_CMD_USB like we do with CONFIG_MXC_SPI
since the USB subsystem will error out of the compile for us.

Additionally, the following behaviors have changed;

* Smartbook "preboot" should not set input and output to USB keyboard as
  there is no display support
* board_eth_init is implemented such that it does not cause U-Boot to
  report an explicit failure ("CPU Net Initialization Failed").

Since Ethernet is implemented via USB (fixed on Smarttop, pluggable on
Smartbook, and handled by "usb start") - the warning that is left
("No ethernet found") is perfectly reasonable at the point it is printed
since the USB system hasn't been started and nothing has been probed yet.

c16ecb0908 M28: Fix the use of gpmi-nand in mtdparts
The mtd name of the NAND in Linux is "gpmi-nand", not "gpmi-nand.0" as
it would be expected, since the controller doesn't support multiple NANDs
attached to it as of now. Rectify this flub by adjusting default mtdparts.

e5ab702a6c powerpc: re-add bi_ip_addr to bd_t struct
Since commit 50a47d0523
(net: punt bd->bi_ip_addr) booting old 2.4.x ppc kernels
is broken due to changed offsets of the fields in struct bd_t.
Offsets of the fields after removed bi_ip_addr are wrong,
causing wrong bus clocks and console baudrate configurations
and various other issues. Re-add the bi_ip_addr field to preserve
backward compatibility with older ppc kernels. Setting bi_ip_addr
in board.c is not really needed, grepping in the 2.4 linux tree
shows that bi_ip_addr is not accessed there. Adding bi_ip_addr
to struct bd_t for other arches isn't needed it seems. bd_t is
not used by other arches in the 2.4 linux tree.

When a variable which contains a user-supplied value is dereferenced
(e.g. to be echo'ed), make sure that the value is not further parsed
by hush.

Set the hush local variable "HUSH_NO_EVAL=1" to enable this behavior.

Without this patch, a sequence like this occurs:

	Panda # env set my_user_string Bob\'s favorite device
	Panda # print my_user_string
	my_user_string=Bob's favorite device
	Panda # echo $my_user_string
	syntax error hush.c:3007

With this patch, it looks like this:

	Panda # HUSH_NO_EVAL=1

df930e9b3c rtc: pcf8563: Make century compatible with Linux
This driver uses the century bit of this RTC in the opposite way Linux does.
From Linux's rtc-pcf8563.c:
	/*
	 * The meaning of MO_C bit varies by the chip type.
	 * From PCF8563 datasheet: this bit is toggled when the years
	 * register overflows from 99 to 00
	 *   0 indicates the century is 20xx
	 *   1 indicates the century is 19xx
	 * From RTC8564 datasheet: this bit indicates change of
	 * century. When the year digit data overflows from 99 to 00,
	 * this bit is set. By presetting it to 0 while still in the
	 * 20th century, it will be set in year 2000, ...
	 * There seems no reliable way to know how the system use this
	 * bit.  So let's do it heuristically, assuming we are live in
	 * 1970...2069.
	 */

As U-Boot's PCF8563 driver does not say it is supposed to support the RTC8564,
make this driver compatible with Linux's by giving the opposite meaning to the
century bit.

c7379149ff patman: don't mess with signoffs
Currently patman assumes that there should be only one Signoff line
and this is obviously incorrect: we often have to work with patches
containing other people signoffs. Moreover, it's really desirable
to preserve the comments between signoffs.

So until some sophisticated signoff processing will be developed I
suggest just don't mess with signoffs at all and treat them like
plain text lines. The only drawback I've found so far is the case
where you have a patch with someones else signoff but not yours and
also have to patman tags under signoff line. In this case you will
get extra empty line between signoffs.

69fd2d3b05 pci: add CONFIG_PCI_ENUM_ONLY for platforms that don't need PCI setup done
Introduce CONFIG_PCI_ENUM_ONLY variable for platforms that just want a
quick enumberation of the PCI devices, but don't need any setup work done.
This is very beneficial on platforms that have u-boot loaded by another
boot loader which does a more sophisticated job of setup of PCI devices
than u-boot.  That way, u-boot can just read what's there and get on
with life.  This is what SeaBIOS does.

bdfd59aa0f at91: atmel_nand: Update driver to support Programmable Multibit ECC controller
The Programmable Multibit ECC (PMECC) controller is a programmable binary
BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller
can be used to support both SLC and MLC NAND Flash devices. It supports to
generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data.

To use PMECC in this driver, the user needs to set the PMECC correction
capability, the sector size and ROM lookup table offsets in board config file.

This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference
is in this version it uses registers structure access hardware instead of using macros.
It is tested in 9x5 serial boards.

5cec214ecd ehci-hcd: Boost transfer speed
This patch takes advantage of the hardware EHCI qTD queuing mechanism to avoid
software and transfer splitting overhead so as to make transfers as fast as
possible.

The only drawback is a call to memalign. However, this is fast compared to the
transfer timings, and the heap size to allocate is small, e.g. 128 kiB in the
worst case for a transfer length of 65535 packets of 512 bytes.

Tested on i.MX25, i.MX35 and i.MX51. In my test conditions, the speed gain was
very significant (several times faster), which is really appreciable when
accessing large files.

The i.MX28 is omitted because its architecture is a bit different (like imx/mxc
vs. mxs in Linux).

10e2178b43 efikamx: sync Smartbook DDR settings in DCD with those found in Genesi's production U-Boot
We have no idea where the DCD was derived from for Smartbook support, but they
differ from the Smarttop settings, MX51EVK settings and certainly don't
correspond to any shipped or development version of U-Boot that Genesi has ever
had on any Smartbook.

So, copy the calibrated, verified settings from the U-Boot as shipped with every
Smartbook since retail production. Remove those few settings that just set the
POR defaults which have already been confirmed for the previous Smarttop DCD
change.

One of the lines is specific to i.MX51 TO3 designs and therefore TO2 Smartbooks
will possibly not work so reliably with this new DCD; that said, TO2 Smartbooks
basically don't exist at retail and the number of units in the world is less
than 5 (3 of which are at the Genesi office or owned by Genesi employees).

Many hours of memory testing confirms the new settings are stable.

Patch v2:
 * picked the correct commit from our development tree, correcting tuned DDR ODF setting
   (which was correct anyway)

fdd63c9352 efikamx: update to Efika MX Smarttop and Smartbook boards
This is a rework of a previously submitted patchset and bundles the
main board support and USB support into a single commit.

It requires the patch "mx5: add iomux-mx51.h include"

* Use iomux-mx51.h include to simplify board configuration.
* Simplify LED support (remove efikamx_toggle_led, change lit LEDs).
* Simplify MMC support for CD and WP pin differences.
* Fix broken CPU voltage setting - comment said 1.1V but the code set to
  1.2V. It should never have been set to 1.2V even on i.MX51 TO2 and
  all available Linux kernels would drop the voltage to 1.1V anyway and
  work reliably. This should lower power consumption during the boot
  process.
* Function renames for readability.
* Some board identification string changes to match actual product names.
* Passes checkpatch (v2)

0001c9f71e efikamx: configure Smarttop PCBID and LED pads in DCD for convenience
PCBID pads seem to need time to settle due to external pulldowns, otherwise
we are reading floating GPIO pins with implicit pad pullups and get the wrong
data. However we can't "wait" at the time we need them before relocation,
since timers are not available. The time taken to get from DCD to the code
requiring the pads set seems to be more than long enough (even with caches
enabled).

We have space in the DCD due to the DDR settings changes to configure all
the pad settings we need for this, plus the LED pad settings too which
reduces the amount of code required later on.

ff9ab7c2e4 efikamx: remove drive strength function and roll its functionality into the DCD
Efika MX boards configure their DDR pad settings twice, one in the DCD generated
from imximage_*.cfg and again in init_drive_strength called before relocation.

Rather than doing this, roll the changes it makes into the DCD so DDR is set up
before a single line of code in U-Boot is run.

The settings are identical with this DCD block which is shorter (by 7 entries)
than the old one, and after the output of init_drive_strength since a lot of the
functionality in the existing DCD and init_drive_strength function was just
setting the POR defaults. This goes to explain some now-missing entries.

Several hundred rounds of mtest have been run to test the settings before and
after to confirm DDR is stable and no ill-effects have been found.

1b0f5597fb MX28: Drop the cp15 reconfiguration from SPL
The SPL doesn't need the CP15 reconfiguration, as that's what the
BootROM does for us already. Moreover, when the CP15 is reconfigured
and the code returns control to BootROM, the USB boot works no more.

Remove the code and allow [1] to work properly as well.

0d04f34a35 ARM: add Raspberry Pi model B board, using BCM2835 SoC
The Raspberry Pi model B uses the BCM2835 SoC, has 256MB of RAM,
contains an SMSC 9512 USB LAN/Hub chip, and various IO connectors.
For more details, see http://www.raspberrypi.org/.

Various portions (cache enable, MACH_TYPE setup, RAM size limit, stack
relocation to top of RAM) extracted from work by:
Oleksandr Tymoshenko <gonzo@bluezbox.com>.

efad6cf881 ARM: add basic support for the Broadcom BCM2835 SoC
This SoC is used in the Raspberry Pi, for example.

For more details, see:
http://www.broadcom.com/products/BCM2835
http://www.raspberrypi.org/wp-content/uploads/2012/02/BCM2835-ARM-Peripherals.pdf.

Initial support is enough to boot to a serial console, execute a minimal
set of U-Boot commands, download data over a serial port, and boot a
Linux kernel. No storage or network drivers are implemented.

d43950463c arm: omap: Fix switching back to nandecc sw.
Orjan Friberg wrote at [1]:

"For the beagleboard, ecc.size is not explicitly set when doing 'nandecc
sw'. If it's not set for the NAND_ECC_SOFT case in nand_scan_tail, it's
set to 256 bytes.

When doing 'nandecc hw', ecc.size is set to 512 bytes. Hence, when
changing back to 'nandecc sw' ecc.size remains at 512 bytes and suddenly
the format has changed."

No patch has been submitted and the issue was still present. This patch
adds the mentioned solution. Tested on a tam3517 board.

This patch updates secure_emif_sdram_config with the
same value written to sdram_config during ddr3 initialization.

During suspend/resume, this value is copied into sdram_config.
With this, a write to sdram_config at the end of resume sequence
which triggers an init sequence can be avoided.

Without this register write in place, the DDR_RESET line goes
low for a few cycles during resume which is a violation of the
JEDEC spec.

The DMA transfers happen only if the transfered data are larger

optimization.

The DMA transfer doesn't work if unaligned transfer is requested
due to the limitation of the DMA controller. This has to be fixed
by introducing generic bounce buffer. Therefore the DMA feature
is now disabled by default.

be7d257895 DaVinci DA8xx: fix set_cpu_clk_info()
For the DA8xx family of SoCs, the set_cpu_clk_info() function was not
initialising the DSP frequency, leading to 'bdinfo' command output such as:

  [...snip...]
  ARM frequency = 300 MHz
  DSP frequency = -536870913 MHz
  DDR frequency = 300 MHz

This commit provides a separate implementation of set_cpu_clk_info() for
the DA8xx SoCs that initialises the DSP frequency to zero (since
currently the DSP is not enabled by U-Boot on any DA8xx platform). The
separate implementation is justified because there is no common code
between DA8xx and the other SoC families. It is now much easier to
understand the flow of the two separate functions.

0d986e61e2 da850/omap-l138: Add support to read u-boot image from MMC/SD
DA850/OMAP-L138 does not support strict MMC/SD boot mode. SPL will
be in SPI flash and U-Boot image will be in MMC/SD card. SPL will
do the low level initialization and then loads the u-boot image
from MMC/SD card.

Define CONFIG_SPL_MMC_LOAD macro in the DA850/OMAP-L138
configuration file to enable this feature.

I've tested it with EEPROM (16 bit address) and TPS65217 chip

Unfortunately I don't have access to any compatible hardware

with deviceid 0x16 on mgcoge. So move the code for this work around to

This patch makes sure that we always use the GNU ld. U-Boot uses certain
construct e.g. OVERLAY which are not implemented in gold therefore it
always needs GNU ld for linking.

It works well if default linker in toolchain is GNU ld but in some
cases we can have gold to be the default linker and also ship GNU ld
but not as default in such cases its called $(PREFIX)ld.bfd, with this
patch we make sure that if $(PREFIX)ld.bfd exists than we use that for
our ld.

This way it does not matter what the default ld is.

aa99f78538 Makefile: allow appending to LIB in sub-makefiles
The top Makefile and the SPL Makefile have lines like those:

ifneq ($(CONFIG_AM33XX)$(CONFIG_OMAP34XX)$(CONFIG_OMAP44XX)$(CONFIG_OMAP54XX),)
LIBS += $(CPUDIR)/omap-common/libomap-common.o
endif

ifeq ($(SOC),mx5)
LIBS += $(CPUDIR)/imx-common/libimx-common.o
endif

This should be done in the arch/CPU/SoC specific sub-makefiles to
keep the top Makefiles clean. This patch also allows adding of new
arch/CPU/SoC specific libraries in the future without touching
the top Makefiles.

To run the unit tests use the ut_cmd command available in sandbox:

make sandbox_config
make

Lane muxing on p2041 is controlled by a reg in CPLD, offset of this reg

muxing according to RCW, which indicates what SerDes protocol it is running.

Default lane muxing map is as below:
Lane G on bank1 routes to SGMII, controlled by bit 1 of the reg;
Lane A on bank2 routes to AURORA, controlled by bit 0 of the reg;
Lane C/D on bank2 routes to SATA0 and SATA1, controlled by bit 2
and bit 3 respectively.

Default value of these bits for lane muxing is '1', we should set or clear

PSDMR_WRC was set to 1C as it should lead to better performance.

c9718210b1 powerpc/82xx: use SDRAM detection for mgcoge2ne
mgcoge2ne was an intermediate step towards mgcoge3ne. One difference is the
smaller SDRAM on mgcoge2ne (128MB). To support both boards with the same
u-boot we use here the SDRAM detection.

This patch enables SDRAM detection between 256MB and 128MB.
So in addition to the existing 256MB geometry:
     4 chips x 8M (13 rows, 10 cols) x 16 bit x 4 banks
we can now also have 128MB geometry:
     4 chips x 4M (13 rows,  9 cols) x 16 bit x 4 banks

3a532346fc powerpc/82xx: add SDRAM detection for km82xx
This patch adds SDRAM detection feature to km82xx boards.
To enable this feature, define CONFIG_SYS_SDRAM_LIST as the initializer
for an array of struct sdram_conf_s.
These structs will expose the bitfields within registers PSDMR and OR1 which
have to be different between configurations; common bitfields will be
defined, as usual, within CONFIG_SYS_PSDMR and CONFIG_SYS_OR1.
If CONFIG_SYS_SDRAM_LIST is not defined, then the usual behavior is retained.

This is an improved version of the driver patch original
submitted by Graeme Smecher <graeme.smecher@mail.mcgill.ca>

The changes are:
    - remove hard coded Xilinx BSP defines (XPAR_SPI_*) and
      use CONFIG_SYS_SPI_BASE from config.h instead
    - add extensive register struct definitions
    - remove offset calculation for register access and
      use the new register struct instead
    - move default SPI controller configuration from
      spi_setup_slave() to spi_claim_bus()
    - add spi_set_speed()
    - insert SPI controller deactivation in spi_release_bus()
    - protect while loops in spi_xfer() with counter / timeouts
    - support SPI mode flags: LSB_FIRST, CPHA, CPOL, LOOP

the driver handles the GETHER.

262350932c net: sh_eth: add SH_ETH_TYPE_ condition
At the moment, the driver supports the following CPUs:
 - GETHER (Gigabit Ethernet) : SH7763, SH7734
 - ETHER  (Fast Ethernet)    : SH7724, SH7757

And the driver had the following "#if":

 #if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734)
 #if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724)
 - Those are for GETHER

 #if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757)
 - This is for ETHER

So, for clean up the code, this patch adds SH_ETH_TYPE_GETHER and
SH_ETH_TYPE_ETHER. And then, the patch modifies the above "#if".

9d2d924a0a net: fec_mxc: Fix setting of RCR for xMII
At least on i.MX25, the RMII mode did not work, which is fixed by this patch.

The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.

According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,
so avoid an invalid assumption. Actually, the choice between half and full
duplex also depends on the endpoint/switch/repeater configuration, so a config
option could be added for that, but there has been no need for it so far.

This commit is an add-on to f6c4191f. There are a few registers where
consecutive writes to the same location should be avoided or have a delay.

According to Synopsys, here is a list of the registers and bit(s) where
consecutive writes should be avoided or a delay is required:

DMA Registers:
Register 0        Bit 7
Register 6        All bits except for 24, 16-13, 2-1.

GMAC Registers:
Registers 0-3     All bits
Registers 6-7     All bits
Register 10       All bits
Register 11       All bits except for 5-6.
Registers 16-47   All bits
Register 48       All bits except for 18-16, 14.

bc46dfac2f net: tftp: fix type of block arg to store_block
The block argument for store_block can be -1 when the tftp sequence
number rolls over (i.e TftpBlock == 0), so the first argument to
store_block has to be of type 'int' instead of 'unsigned'.

In our environment (gcc 4.4.5 mips toolchain), this causes incorrect
'offset' to be generated for storing the block, and the tftp block
with number 0 will be written elsewhere, resulting in a bad block in
the downloaded file and a memory corruption.

a1d2478e2d fdt: Add board specific dts inclusion
Some architectures, for example Microblaze, doesn't need a
splitted device tree because every Microblaze hw design is
different. The individuell Microblaze device tree will be
auto generated by FPGA design tools and could be used directly
with dtc.

The auto generated dts for Microblaze can not processed by CPP.
Unfortunately that is the default procedure in U-Boot to merge
a splitted device tree (substitution of ARCH_CPU_DTS).

Microblaze will never use the ARCH_CPU_DTS substitution and we
introduce the new board specific substitution variable BOARD_DTS
that points into vendor/board/dts subdir with the file name
of CONFIG_DEFAULT_DEVICE_TREE. The common dts file in vendor/dts
subdir (defined by CONFIG_DEFAULT_DEVICE_TREE) contain a single
include line that can processed by CPP:

    /include/ BOARD_DTS
