From: Rick Chen Date: Tue, 20 Mar 2018 07:52:58 +0000 (+0800) Subject: mmc: ftsdc010: Merge nds32_mmc to ftsdc010 X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=bf9ba4dbb04bba885330790577ed1e67480ece86;p=u-boot.git mmc: ftsdc010: Merge nds32_mmc to ftsdc010 nsd32_mmc was created to support ftsdc010 dm. It is not necessary to separate both, so merge it to ftsdc010.
