sandbox: block driver using host file/device as backing store Provide a way to use any host file or device as a block device in U-Boot. This can be used to provide filesystem access within U-Boot to an ext2 image file on the host, for example. The support is plumbed into the filesystem and partition interfaces. We don't want to print a message in the driver every time we find a missing device. Pass the information back to the caller where a message can be printed if desired.

dm: sandbox: Add driver-model block-device support for sandbox Update the host driver to support driver model for block devices. A future commit will remove the old code, but for now it is useful to be able to use it both with and without CONFIG_BLK.

dm: Drop the block_dev_desc_t typedef Use 'struct' instead of a typdef. Also since 'struct block_dev_desc' is long and causes 80-column violations, rename it to struct blk_desc.
