[PATCH] Add Kconfig option for altbootcmd when using CONFIG_BOOTCOUNT_LIMIT

[Tomáš Peterka]

Hello u-boot maintainers,

I would like to merge a simple patch for user-friendliness when configuring u-boot with Yocto. The problem is missing option for altbootcmd when using the feature CONFIG_BOOTCOUNT_LIMIT.  Simply adding the option CONFIG_BOOTCOUNT_ALTBOOTCMD into Kconfig shouldn't be a problem when there is already CONFIG_BOOTCOMMAND? Users then can use CONFIG_BOOTCOUNT_ALTBOOTCMD instead of misusing CFG_EXTRA_ENV_SETTINGS (and friends) that are usually used by configs of specific boards.

Many thanks for considering this,
Tomas
