This is a demo that CM4 will boot up by u-boot without typing any
command. It boots up at u-boot early init, try to minimize the time
from power up to the CM4 running.
Since CM4 runs on QSPI NOR XIP, we have to disable the QSPI driver in
u-boot to avoid conflict.
RDC for shared GPIO1 is added, but not enabled, because the kernel is
not ready for shared GPIO1. Users can uncomment the CONFIG_IMX_RDC to
enable it.
Some legacy codes in mx6sxsabreauto are removed. We only need this work
on mx6sxsabresd as a demo.

Integrate the FSL android fastboot features into community's fastboot.
1. Use USB gadget g_dnl driver
2. Integrate the FSL SD/SATA/NAND flash operations, since the GPT and
EFI partitions are not support by i.MX.
3. Add FDT support to community's android image.
4. Add a new boot command "boota" for android image boot. The boota
implements to load ramdisk and fdt to their loading addresses
specified in boot.img header, while bootm won't do it for android image.
5. Support the authentication of boot.img at the "load_addr" for
both SD and NAND.
6. We use new configuration CONFIG_FSL_FASTBOOT for Freescale's fastboot
with relevant header file "fsl_fastboot.h". While disabling the
configuration, the community fastboot is used.
7. Overwrite the cmdline in boot.img by using bootargs saved in local environment.
8. Add recovery and reboot-bootloader support.

There are two problems in EHCI driver for mx7, and cause the OTG ID detection
failed to work.
1. The offset for phy_status register in usbnc_regs is not correct.
2. We should clear the USBNC_PHYCFG2_ACAENB bit to enable the OTG ID detection,
not set it. When the bit is set, the ACA Resistance Detection is enabled,
which disables the OTG ID detection, because the internal pull up is off.

On i.MX7D TO1.1, design team adds a mux cell at the CKE path to fix the suspend
mode reset issue, but seems it add extra delay on CKE path, so CKE-CK timing violated.
When DDR enters self-refresh or retention for long time(> 15seconds per testing on some boards),
DDR data corruption occured, not able to decrease CKE delay, so we have to add extra
delay on all other signals to balance it.
DDR script needs to be fine-tuned according to this hardware change.
For DDR3, since the timing margin is not good, we have to decrease the DDR frequency from
533Mhz to 400Mhz.
We uses TO1.1 script at default, and retains the TO1.0 script for reference.

Port LDO bypass support from v2015 to support the features:
1. Add check for 1.2GHz core speed. If Speed grading fuse is for 1.2GHz,
enable LDO bypass and setup PMIC voltages. LDO bypass is dependent
on the flatten device tree file.
2. We set WDOG_B in set_anatop_bypass() before, because it is the only case, but now
on i.mx6sabreauto board, we didn't use ldo-bypass mode, but have to use WDOG_B to
reboot whole board, so split these code to independent function so that board file

MLK-12034 imx: mx7dsabresd: Add RevB board support
Since i.MX7D SDB revB board has some HW changes, we have modify the BSP file to support new pinmux.
1. OTG2 PWR pin is changed to GPIO1_IO07.
2. A enet2_en pin is added for isolating enet2 signals with EPDC, we also add support for enet2.
3. pin6 of 74LV output is changed for CSI PWDN. Set output to high to power down it.
This patch also tries to get the board id and apply changes according with it. Since current
RevB board does not burn GP1 fuse for board id, we have to check the TO rev instead even it is not very
exact. Will update this if any new way implemented.

Also update pmic settings to align with datasheet.

"
Current uboot supports for running LPDDR2 at 400MHz on MX6Q ARM2 board,
but there is a problem in switching pre_periph_clk_sel to pll2_pfd2.
We cannot directly change the parent of pre_periph_clk_sel as this mux
is not a glitchless mux. We need to follow the correct procedure and wait
for the busy bits to clear before switching.
Change to follow the procedure:
1. Set periph_clk2 to OSC.
2. Switch the periph_clk to periph_clk2, checking the CCM_CDHIPR for
periph_clk , ahb_podf and axi_podf busy bits.
3. Setting the pre_periph_clk to PLL2 PFD 396M.
4. Switch the periph_clk back to pre_periph_clk and checking CCM_CDHIPR
busy bits.
