This serie permits using any block device as target for fastboot by moving the generic block logic into a common set of helpers and also use them as generic backend.
The erase logic has been extended to support software erase since only 2 block drivers exposes the erase operation. Tests are welcome to make sure this series doesn't introduce any regressions on the emmc backend.
