Subject: sunxi: Update sunxi-common.h to deal with different DRAM base addr on sun9i
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=e049fe282622d78fcc8f2ab9fe00cd186a542fa2;p=u-boot.git

sunxi: Update sunxi-common.h to deal with different DRAM base addr on sun9i

The DRAM Base differs between sun9i and the others, update sunxi-common.h to
deal with this.
