Subject: [PATCH] MIPS: BCM47XX: Drop WGT634U hacks
|
|
MIME-Version: 1.0

|
Content-Type: text/plain; charset=UTF-8

This old wgt634u.c was trying to implement a bit ugly support for
|
|
Netgear WGT634U. It provided info about LED, flash mapping & layout and
|
|
was trying to handle reset button.
|
|
|
|
This is not needed anymore as we have replacement for all this stuff.
