ar71xx: ubnt-m-xw: Fix factory image flashing using TFTP recovery
This is backport of the same functionality in ath79, from commit
d42a7c469 ("ath79: ubnt-m-xw: Fix factory image flashing using TFTP
recovery method")
Ubiquity allows flashing of unsigned factory images via TFTP recovery
method[1]. They claim in airOS v6.0.7 release changelog[2] following:
All future airOS versions will be signed in this way and not allow
unsigned firmware to be loaded except via TFTP.
U-boot bootloader on M-XW devices expects factory image revision
version in specific format. On airOS v6.1.7 with `U-Boot 1.1.4-s1039
(May 24 2017 - 15:58:18)` bootloader checks if the revision major(?)
number is actually a number, but in currently generated images there's
OpenWrt text and so the check fails:
Hit any key to stop autoboot: 0
Setting default IP 192.168.1.20
Starting TFTP server...
Receiving file from 192.168.1.25:38438
Received 4981148 bytes
Firmware check failed! (1)
By placing arbitrary correct number first in major version, we make the
bootloader happy and we can flash factory images over TFTP again:
Received 3801500 bytes
Firmware Version: XW.ar934x.v6.0.4-42.OpenWrt-r9766+2-be42e44
Setting U-Boot environment variables
Un-Protected 1 sectors
Erasing Flash.... done
Patch provided by AREDN[3] project, tested on Bullet M2 XW.
