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.
