MLK-9819 ARM: imx6sx: Add WDOG_B reset for i.mx6sx boards.
QSPI-NOR reboot failed in case of larger flash size such as 256M used, because
kernel QSPI-NOR flash use 4-bytes-address mode to visit 16MB+ area but ROM code
use 3-bytes-address mode to access QSPI-NOR. Thus, we have to use WDOG_B to
reset QSPI-NOR flash to workaround this.
Note:
Please update the u-boot with the below u-boot patch, otherwise system will
reboot endless while kernel boot:
