Subject: powerpc/km82xx: remove 82xx specific functions from common.c
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=1adfd9dd3fc1bacc3c3a1fe8790f258916483fce;p=u-boot.git

powerpc/km82xx: remove 82xx specific functions from common.c

Common code should be valid for more than one architecture,
therefore the km82xx specific code was removed from common.c.
