toradex: imx8: enable BOOTCOUNT feature
This introduces automatic boot counter that increases after every reset.
After a power-on reset, it will be initialized with 1, and each
reboot will increment the value by 1. By default it's disabled
if bootlimit isn't set.
To enable this feature you have set bootcount limit ("bootlimit"),
alternate boot action ("altbootcmd") that will be performed if
the new value of bootcount exceeds the value of bootlimit, and
"upgrade_available" to let U-Boot automatically increase and save
the counter value after every reset:
> setenv bootlimit 5
> setenv upgrade_available 1
> setenv altbootcmd "bootm ..."
In case the bootlimit exceeds, the message will be shown and albootcmd
executed:
Warning: Bootlimit (5) exceeded. Using altbootcmd.
To reset bootcount run:
> bootcount reset
Print current value:
> bootcount print
