Subject: m68k: powerpc: Clean up do_mdm_init
X-Git-Tag: v2014.07-rc3~58
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9272a9b4f637347267329c7dc48712ea6c31feaa;p=platform%2Fkernel%2Fu-boot.git

m68k: powerpc: Clean up do_mdm_init

This code seems unnecessarily complex. We really just need to check the
global_data. Now that is it all in one place, and not arch-specific, this
is pretty easy.
