We only need the function found in cmd/disk.c when we have IDE, SCSI or USB_STORAGE enabled. While the first two are easy to get right, in the 3rd case we assume that the set of cases where we do have USB and do not enable USB_STORAGE are small enough that we can take the small bloat of un-discarded strings on gcc prior to 6.x Signed-off-by: Tom Rini <trini@konsulko.com>
