Subject: layerscape: use the lmb API's to add RAM memory
X-Git-Url: http://git.dujemihanovic.xyz/html/static/git-favicon.png?a=commitdiff_plain;h=9ec406555714b0dd1edba151b071cb17e6dcbcb0;p=u-boot.git

layerscape: use the lmb API's to add RAM memory

The EFI memory allocations are now being done through the LMB module,
and hence the memory map is maintained by the LMB module. Use the
lmb_arch_add_memory() API function to add the usable RAM memory to the
LMB's memory map.
