[U-Boot] [PATCH v2 00/24] dm: mmc: Add driver-model block-device support to MMC

[Simon Glass]

This series adds support for using CONFIG_BLK with MMC, such that it uses
the block interface correctly. The old interface in part.c is removed.

With driver model, when CONFIG_BLK is enabled, MMC devices must have a child
block device. A new mmc_bind() function takes care of this. It should be
called when new MMC devices are bound.

MMC support is added to sandbox along with a simple driver-model test.

Code size does unfortunately increase slightly in SPL. For example firefly
(Thumb 2) adds 128 bytes of code overall due to the new block driver table
support. There may be some potential after this series to rationalise the
common/spl/ implementations and reduce code size a little, but that remains
to be seen.

This series follows on from the previous series which refactored block
devices. It is available at u-boot-dm/blkb-working

Changes in v2:
- Rebase to master
