disk: allow - or empty string to fall back to $bootdevice
Commit 10a37fd "disk: get_device_and_partition() "auto" partition" prevented the use of "-" on the command-line to request fallback to the $bootdevice environment variable instead. This patch allows that, or an empty string "" to be used. Tested: setenv bootfile /boot/zImage setenv bootdevice 0:1 ext2load mmc 0:1 ext2load mmc - ext2load mmc "" Signed-off-by: Stephen Warren <swarren@nvidia.com>
