ipq40xx: Fix reboot on EnGenius ENS620EXT
This patch works around an issue where reboot would cause the AP
to power down and not reboot.
The ipq4019 restart controller reboot causes the system
to power down and not recover. Fix is to disable the restart
controller in the device tree and the device reverts to
using the watchdog to perform the reset.
The real problem is due to the buggy bootloader that ships
with the device. Steve Glennon reported in the PR for this
patch: <https://github.com/openwrt/openwrt/pull/2009> that:
"the problem was due to a bad u-boot that ships with the device.
Using the u-boot that comes with 3.5.5.3 EnGenius factory
software now allows the old code (using the do_msm_reboot)
to reboot successfully.
On to the bad news:
Well 3.5.5.3 is a bad path. Finally managed to recover. You
CANNOT use prior EnGenius firmware to downgrade.
Findings:
* They now password protect the serial console with a new, unkown
password.
* They changed the protection on their walled-garden. I have to
use the ssh admin@ip /bin/sh --login to get out of their
walled-garden.
* Attempts to flash the original 3.0.0 or 3.0.1 EnGenius firmware
fail through the UI and sysupgrade. Their firmware update GUI now
seem to detect regular openwrt images, but they fail to flash
Attempts to flash a normal OpenWrt image with sysupgrade fail.
[..]
Attempts to sysupgrade with EnGenius firmware fail with the same
"mandatory section(s) missing" error, so you cannot downgrade to
3.0.0 or 3.0.1."
