Subject: [PATCH] Revert "sandbox: Change md command to use map_physmem"
This reverts commit 355a835747c6f7c5071ead295a7dfc489c73cb03.
The original commit broke long standing assumption that md commands work
on effective addresses. This normally isn't an issue for most systems
that map 1:1, however on systems with a 36-bit address map it breaks.
