Subject: board: arbel: correct the dram bank size
X-Git-Url: http://git.dujemihanovic.xyz/%22/img/sics.gif/%22/static/git-favicon.png?a=commitdiff_plain;h=d01ba96a8cc4f2563f643491a80ee9a92f20a757;p=u-boot.git

board: arbel: correct the dram bank size

If CONFIG_SYS_MEM_TOP_HIDE is defined, gd->ram_size is reduced by
CONFIG_SYS_MEM_TOP_HIDE. Need to correct the actual ram size in
dram_init_banksize.
