Uboot raspberry pi watchdog disabled by mistake

[Laurentiu-Cristian Duca]

Hello uboot community,

  In 2019, commit [1] deleted commit [2].
Commit [2] implemented the watchdog feature for raspberry pi.
The delete reason is, I quote, "The BCM2835/2836 watchdog is not used
in mainline U-Boot at all".

  I am using commit [2] in conjunction with bootlimit:
- uboot increments bootcount, enables watchdog and boots linux using bootcmd
- if linux hangs, the watchdog resets the board
- in uboot, if bootcount > bootlimit then boot using altbootcmd and
boots another partition
with linux

  So, there is use of commit [2] and I consider that commit [1] is a mistake.

Thank you,
