+Subject: [PATCH] MIPS: BCM47XX: Drop WGT634U hacks
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
