4Subject: [PATCH] config/ast-common: Add conditional factory reset command
5
6Factory reset (removing persistant rwfs) has to occur before we've
7mounted the rwfs. However, the variable to determine whether or not to
8do the reset is stored in the u-boot env. This is tricky to access
9before rwfs is mounted except in u-boot. So, check it before every boot.
