ramips: add support for TP-Link Archer C6U v1 (EU)
This patch adds support for TP-Link Archer C6U v1 (EU).
The device is also known in some market as Archer C6 v3.
This patch supports only Archer C6U v1 (EU).
Install the OpenWrt factory image for C6U is from the
TP-Link web interface.
1) Go to "Advanced/System Tools/Firmware Update".
2) Click "Browse" and upload the OpenWrt factory image:
openwrt-ramips-mt7621-tplink_archer-c6u-v1-squashfs-factory.bin.
3) Click the "Upgrade" button, and select "Yes" when prompted.
Recovery to stock firmware:
--------------------------
The C6U bootloader has a failsafe mode that provides a web
interface (running at 192.168.0.1) for reverting back to the
stock TP-Link firmware. The failsafe interface is triggered
from the serial console or on failed kernel boot. Unfortunately,
there's no key combination that enables the failsafe mode. This
gives us two options for recovery:
1) Recover using the serial console (J1 header).
The recovery interface can be selected by hitting 'x' when
prompted on boot.
2) Trigger the bootloader failsafe mode.
A more dangerous option is force the bootloader into
recovery mode by erasing the OpenWrt partition from the
OpenWrt's shell - e.g "mtd erase firmware". Please be
careful, since erasing the wrong partition can brick
your device.
