Since commit c98b47f1ff60 ("MLK-22749 imx8mq: Add workaround to fix sticky
bits lock up") it's not possible to build i.MX8MM and i.MX8MN targets with
CONFIG_SECURE_BOOT enabled:CC cmd/version.o
arch/arm/mach-imx/imx8m/soc.c:326:23: error: ‘CONFIG_IMX_UNIQUE_ID’ undeclared \
(first use in this function); did you mean ‘CONFIG_IMX_VIDEO_SKIP’?
if (!is_uid_matched(CONFIG_IMX_UNIQUE_ID))
^~~~~~~~~~~~~~~~~~~~The OCOTP sticky bit workaround is only needed for i.MX8MQ devices, other devices
should not build the secure_lockup() function.Add CONFIG_IMX8MQ to the conditional compilation to avoid such issue.

Current flexspi driver enables the Quad DTR read, so the measured
100Mhz SCLK is actually for DTR mode not SDR. However, according to
MT25QU256ABA datasheet, this flash only supports max DTR at 90Mhz and
max SDR at 166Mhz. It means current clock setting violate the flash
spec. So change back the flexspi clock to align with imx8mm.Signed-off-by: Ye Li

On B1 chips with HAB v4.4, the sticky bits are not locked up in
HAB closed mode. We introduce a workaround in SPL to lock up
these bits and clear Manufacturing Protection Private Key for
secure boot.For field return case, user has to build a SPL with
CONFIG_SECURE_STICKY_BITS_LOCKUP=n and set CONFIG_IMX_UNIQUE_ID to
part's unique id. When the UID check is passed, sticky bits are not
lockup and users can burn field return fuse. Otherwise the boot will
stop.Signed-off-by: Ye Li

ROM SError happens on two cases:
1. ERR050342, on iMX8MQ HDCP enabled parts ROM writes to GPV1 register, but
when ROM patch lock is fused, this write will cause SError.2. ERR050350, on iMX8MQ/MM/MN, when the field return fuse is burned, HAB
is field return mode, but the last 4K of ROM is still protected and cause SError.Since ROM mask SError until ATF unmask it, so then ATF always meets the exception.
This patch works around the issue in SPL by enabling SPL Exception vectors table
and the SError exception, take the exception to eret immediately to clear the SError.Signed-off-by: Ye Li

Update the mx7ulp wdog disable sequence to avoid potential reset issue
in unlock or refresh sequence. Both sequence need two words write
to wdog CNT register in 16 bus clocks window, if miss the window,
the write will cause violation in wdog and reset the chip.Current u-boot code is using writel() function which has a DMB barrier
to order the memory access. The DMB between two words write may introduce
some delay in certain circumstance, causing the wdog reset due to 16 bus
clock window requirement.This patch replaces writel() function by __raw_writel() to avoid such issue,
and improve to check if watchdog is already disabled or unlocked.Signed-off-by: Ye Li

When enable u-boot splash screen and set kernel dtb with -hdmi.dtb on
imx8qm, the kernel reboot (partition reboot) will hang in u-boot if HDMI
cable is plugged in.
The root cause is kernel set the clock source of DC0 display0 channel to
bypass clock, when doing reboot this clock setting may not be cleared. So
u-boot has wrong clock source and cause lpcg stop bit always set.Fix the issue by adding the clock parent setting and not depend on default
