so once it reaches Kernel proper, that dog is being killed, right ?

iirc, TI AM335x's & AM43x's ROM code too leaves the on-chip watchdog
enabled & the bootloader disables it (else once it boots to prompt, it
reboots always unless watchdog driver [if present] takes care of it),
Lokesh, right ?

But yes, that brings a bootloader dependency.
