According to i.MX7ULP Reference Manual the second word write for both
UNLOCK and REFRESH operations must occur in maximum 16 bus clock.The current 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 a WDOG timeout due to 16 bus
clock window requirement.Replace writel() function by __raw_writel() to achieve a faster memory
access and avoid such issue.Signed-off-by: Breno Lima

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

Since the USB HID limits the maximum bandwidth(3072) for interrupt
endpoint transfers, when the bInterval set to 1, we can only support 3
boards to run sdp at the same time. In order to support more boards,
change the bInterval of interrupt endpoint to 3, which will not affect
the transmission speed.Signed-off-by: Sherry Sun

When use ep1out interrupt endpoint to receive data in sdp, the max

EP0 has been used to transfer file data in sdp before, but the max
packetsize of ep0 is 64 bytes. So in order to improve the file transfer
speed, here add the EP1_OUT interrupt endpoint which max packetsize is
set to 1024 byte.After testing, it turns out that using ep1out is twice as fast as using
ep0 while receiving data in sdp.Signed-off-by: Sherry Sun

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
parent value.Signed-off-by: Ye Li
