> From: Igor Opaniuk <igor.opaniuk at toradex.com>
> 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
