This adds support writing to the sandbox mmc backed by an in-memory buffer. The unit test has been updated to test reading, writing, and erasing. I'm not sure what MMCs erase to; I picked 0, but if it's 0xFF then that can be easily changed. Signed-off-by: Sean Anderson <sean.anderson@seco.com> Reviewed-by: Simon Glass <sjg@chromium.org>
