Subject: ARM: make the machid configurable via the environment
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=3c234efa693bc59906c2be55c7918ecbb55392ea;p=u-boot.git

ARM: make the machid configurable via the environment

If the variable "machid" exists, let do_bootm_linux use that instead
of bd->bi_arch_number.
