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. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Mike Frysinger <vapier@gentoo.org> Tested-by: Matthias Weisser <weisserm@arcor.de>
