Hello uboot community,
In 2019, commit  deleted commit .
Commit  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  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
So, there is use of commit  and I consider that commit  is a mistake.
More information about the U-Boot
