Add configs and board level codes for i.MX6ULL 14x14 EVK. Very similar
board from i.MX6UL EVK. I2C, UART, USB, QSPI, SD, ENET and LCD are ok
to work.The codes for i.MX6ULL 9x9 EVK is kept. We will add 9x9 build target when
it is needed.The DDR3 script is using version 1.2:
File: EVK_IMX6ULL_DDR3L_400MHz_512MB_16bit_V1.2_NewDRAM.inc
Test: 3 boards passed memtester.

LCD_PWR_EN controls the G pin of Q13 PMOS which needs low voltage to connect
D to S for outputting LCD 3.3V. If LCD_PWR_EN is high, we measured the LCD 3v3
is actually 1.2V.Signed-off-by: Ye Li

In u-boot, i.MX6QP sabresd board uses 125Mhz ref clock from PHY,
While kernel uses the clock from internal PLL by setting GPR5 bit 9.
When doing warm reset in kernel, the GPR regigster is not reset, so
the clock source still is the PLL. This causes ENET in u-boot can't work.In this patch, we change the u-boot to use internal PLL to align with
kernel for i.MX6QP. This also fixes the ENET issue after kernel warm reset.Signed-off-by: Ye Li

On i.MX7D lpddr3, retention mode exit flow should restore
more registers to make sure the ddr controller and ddr phy
settings restored properly, otherwise, some of the boards
can NOT pass memtester after retention mode exited.For LPSR mode, ddr resume flow is same as retention mode,
just adjust it accordingly.Signed-off-by: Anson Huang

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.Signed-off-by: Ye Li

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.Signed-off-by: Ye Li

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.
