[U-Boot] [PATCH v3 0/4] dm: Add driver-model support for block drivers

[Simon Glass]

Recent additions of the MMC and DISK uclasses have indicated that it is time
to look at adding a uclass for block devices. This series does this and
includes a few clean-ups to the partition code also.

A block device is typically a child device of its storage parent. For
example an MMC device will have a block-device child. A USB storage device
may have multiple block-device children, one for each LUN.

With this series only USB storage and 'host' are converted over to use the
new support. Several more remain, including SCSI, IDE and MMC. Each of these
should get its own uclass.

The uclass implements only a few basic features. A few tests are added to
check that things work as expected.

The code size impact of switching to driver model for block devices is
small. One benefit is that it becomes possible to enumerate all block
devices, regardless of their type.

Changes in v3:
- Expand the commit message
- Drop patches already applied

Changes in v2:
- Rename to blk_get_device_by_str()
