Browse Source 
Add an emulation of an SD card to sandbox, allowing MMC to be used in tests.
The emulation is very simple, supporting only card detection and reading
test data.

This select a dummy sandbox MMC driver. At present this does nothing
other than allow sandbox to be build with MMC support. This
