display5: wdt: Enable WDT support (both SPL and u-boot)
Test case:
The fitImage gets corrupted:
truncate -c -s 3M fitImage
run tftp_mmc_fitImg
setenv boot_os y
reset
[board shall hang in SPL with
"Trying to boot from MMC1" information]
Then after X seconds WDT is causing board to reset. After N boot attempts
we enter recovery mode.
