Subject: sandbox: Change md command to use map_physmem
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=355a835747c6f7c5071ead295a7dfc489c73cb03;p=u-boot.git

sandbox: Change md command to use map_physmem

Sandbox wants to support commands which use memory. The map_physmen()
call provides this feature, so should be used more consistently in
U-Boot.
