Great, but please do add a little more code :-)

- doc/usage/cmd
- test/cmd/write.c

For the test you can use sandbox's mmc0 - see dm_test_mmc_blk() for an
example of a test that does that. For checking the command response,
the acpi.c test is an example, although I suppose there is actually no
output.

Simon
