[U-Boot] Uart boot broken on AM335x-evm

Hi All, I am facing an issue with UART boot on AM335x-evm using latest U-Boot. SPL is not able to download u-boot.img completely. After a bit of debug with the help of Andrew, it is watchdog causing the timeout. If HW_WATCHDOG is disabled, SPL is able to download the image completely and u-boot successfully boots up. After this I could not progress anything.

Wondering if anyone else is facing the same issue and any pointers to debug further will be very helpful.

Thanks and regards, Lokesh
