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.
