Subject: [PATCH] sahara: Ignore DONE response code
The DONE message contains a return code denoting if the firmware is done
(1) requesting files from the host, or if there are more requests to
come (0). Unfortunately on some platforms the ROM code sends 0
regardless, so we just have to assume that we're done.
This assumes that there is only ever one image to transfer.
