Subject: samsung: mmc: Drop old MMC init code
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e898799ce475735bed3ac80cbffac3f55c9f091e;p=u-boot.git

samsung: mmc: Drop old MMC init code

Now that these boards use driver model we can drop the old code. At
present s5p_mmc_init() is still used by goni and smdkv310 so cannot be
removed unless we remove those boards.
