c803f24b28 To avoid sleeping in firmware_get() with bwi mutex held, call
bwi_mac_fw_alloc() at the device attach, not in the interface
init.

12e36acb09 Bring in Andrew Thompson's port of Sepherosa Ziehau's bwi driver for
Broadcom BCM43xx chipsets.  This driver uses the v3 firmware that
needs to be fetched separately.  A port will be committed to create
the bwi firmware module.

The driver matches the following chips: Broadcom BCM4301, BCM4307,
BCM4306, BCM4309, BCM4311, BCM4312, BCM4318, BCM4319

The driver works for 802.11b and 802.11g.

Limitations:
	This doesn't support the 802.11a or 802.11n portion of radios.
	Some BCM4306 and BCM4309 cards don't work with Channel 1, 2 or 3.
	Documenation for this firmware is reverse engineered from
		 http://bcm.sipsolutions.net/
	V4 of the firmware is needed for 11a or 11n support
		 http://bcm-v4.sipsolutions.net/
	Firmware needs to be fetched from a third party, port to be committed

# I've tested this with a BCM4319 mini-pci and a BCM4318 CardBus card, and
# not connected it to the build until the firmware port is committed.
