Subject: [PATCH 29/32] bcma: add new PCI ID
This ID was found on the PCIe wireless card on the board of a Netgear
WNDR3400 using a bcm4716. The device with this ID is identified by b43
as "Broadcom 43224 WLAN".

Do not use the CFE console. It causes hangs on some devices like the
Buffalo WHR-HP-G54.

The Netgear wgt634u uses a different format for storing the
configuration. This patch is needed to read out the correct
configuration. The cfe_env.c file uses a different method way to read
out the configuration than the in kernel cfe config reader.
