Common codes changes in the mcc 2.0 updates
- common definitions are moved from mcc_config.h to mcc_common.h
because that these definitions are common for the standalone mcc
stack, and shared by different platforms, such as Linux, MQX.
- re-define the common api _psp_core_num(), and _psp_node_num().
Let them to be no platform dependency.
- move the definition of the MCC_OS_USED in mcc_config.h
- new add on mcc_config_linux.h file, contained the platform
related macro definitions contained in mcc_config.h before.
- add the related linux modifications into mcc_api.c/mcc_common.c
when implement the mcc2.0 into linux BSP.
- fix one potential bug that all the share memory operations should
be protected by sema4.

RNG4 block contains multiple (i.e. 2) state handles that can be
initialized. This patch adds the necessary code for detecting
which of the two state handles has been instantiated by another
piece of software e.g. u-boot and instantiate the other one (or
both if none was instantiated). Only the state handle(s)
instantiated by this driver will be deinstantiated when removing
the module.

The earlier patch for "ENGR00313512 dma: imx-sdma: A bungle of work around for
BUG ON issue" is better not applied for loop mode, since there is no any cookie
touch in loop mode which means never trigger the BUG_ON workaround. Otherwise,
if upper driver such as UART disable dma channel but the device still has sent
the data into the RXFIFO, bd buffer will be consumed quickly and then stop.That
will trigger "RX FIFO overrun", like below log:

This change is required for post SEC-5.0 devices which have RNG4.
Setting RDB in security configuration register allows CAAM to use the
"Random Data Buffer" to be filled by a single request. The Random Data
Buffer is large enough for ten packets to get their IVs from a single
request. If the Random Data Buffer is not enabled, then each IV causes a
separate request, and RNG4 hardware cannot keep up resulting in lower
IPSEC throughput if random IVs are used.

This patch splits the RNG4 state handle instantiation
function into two parts: one that handles the creation
of the descriptor which instructs the CAAM to perform

function that performs the running of the said descriptor

[<vicki.milhoan@freescale.com>: Edited to disable ARM clocks at removal]
Signed-off-by: Victoria Milhoan <vicki.milhoan@freescale.com>
The RNG4 block in CAAM needs to be 'seeded' first before being used
for generating pseudo-random data. The 'seeding' is done by getting
entropy from the TRNG ring oscillator. The RTFRQMAX register controls
the maximum allowable number of samples that can be aquired during
an entropy sample. Depending on the clock at which the RNG4 block
(and for that matter the SEC block) runs, it's possible that a
hard-coded value for the maximum frequency is inadequate, i.e. more
samples than needed are taken. This is an error, and thus the RNG4
block doesn't get initialized. The patch attempts to alleviate
this issue by trying with progressivly larger frequencies, until
the number of samples is adequate.
This patch also fixes how a descriptor is deemed as being finished:
instead of checking the VALID field in the DECO debug register,
it makes sure that the DECO is idle, by checking the DECO state field
of the said register.

Signed-off-by: Victoria Milhoan <vicki.milhoan@freescale.com>
The way the DECO runs a descriptor through the direct (debug)
interface is different from the JRI interface: the DECO will
continue to try and execute the next commands, after the descriptor
buffer has ended. This leads to unpredictable results and possibly
to locking up of the DECO. This patch adds a halt command at the
end of the descriptor to ensure the DECO halts when it reaches
the end of the descriptor buffer.

The i.MX6SX-sabreauto board has an base board which contains a SD
slot, this SD slot is connect to usdhc4, so add usdhc4 in devicetree.
Due to the SD slot is on base board, if we set the usdhc4 pad drive
strength as 87 Ohm, the signal on these pads is not good, usdhc4 can't
get the SD card's status. So change the usdhc4 pad drive strength to
43 Ohm, then usdhc4 can work well for base board.

"Patch ENGR00329450 ARM: imx: set CLK_SET_RATE_GATE for gate and divider clocks"
requires that the particular clock (derived from PLL) need to be disabled before
its rate is changed. While on imx6sx, CSI0 and CSI1 shares the same CSI clock,
which means the CSI clock cannot be disabled then changed the clock when another
CSI module is already working.
Currently the CSI clock is only derived from OSC 24Mhz instead of PLL.
Now use the clk_register_gate() without CLK_SET_RATE_GATE flag by compromise
to make two CSIs work properly.
