[OpenWrt-Devel] [PATCH 2/2] ar71xx: add support for TP-LINK TL-WR841N/ND v10

[Matthias Schiffer]

Thanks, but I know what I'm doing. The hardware is similar enough to
boot with the exact same initialization routines as the v9, thus reusing
the BOARDNAME is fine (it is done like this for other hardware as well -
OpenWrt has a distinction between "board" and "model", where multiple
models can have the same board, but still each model has its own images)

On TP-LINK devices, sysupgrade checks the TPLINK_HWID of the image
against the one in the flash, the BOARDNAME doesn't matter (except to
determine that it is a TP-LINK device).
