  7	  b43 is a driver for the Broadcom 43xx series wireless devices.
  8
  9	  Check "lspci" for something like
 10	  "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
 11	  to determine whether you own such a device.
 12
 13	  This driver supports the new BCM43xx IEEE 802.11G devices, but not
 14	  the old IEEE 802.11B devices. Old devices are supported by
 15	  the b43legacy driver.
 16	  Note that this has nothing to do with the standard that your AccessPoint
 17	  supports (A, B, G or a combination).
 18	  IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
 19
 20	  It is safe to include both b43 and b43legacy as the underlying glue
 21	  layer will automatically load the correct version for your device.
 22
 23	  This driver uses V4 firmware, which must be installed separately using
 24	  b43-fwcutter.
 25
 26	  This driver can be built as a module (recommended) that will be called "b43".
 27	  If unsure, say M.

 54config B43_PCMCIA
 55	bool "Broadcom 43xx PCMCIA device support"
 56	depends on B43 && SSB_PCMCIAHOST_POSSIBLE
 57	select SSB_PCMCIAHOST
 58	---help---
 59	  Broadcom 43xx PCMCIA device support.
 60
 61	  Support for 16bit PCMCIA devices.
 62	  Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
 63	  devices, but 32bit CardBUS devices. CardBUS devices are supported
 64	  out of the box by b43.
 65
 66	  With this config option you can drive b43 cards in
 67	  CompactFlash formfactor in a PCMCIA adaptor.
 68	  CF b43 cards can sometimes be found in handheld PCs.
 69
 70	  It's safe to select Y here, even if you don't have a B43 PCMCIA device.
 71
 72	  If unsure, say N.
 73
 74config B43_SDIO
 75	bool "Broadcom 43xx SDIO device support"
 76	depends on B43 && SSB_SDIOHOST_POSSIBLE
 77	select SSB_SDIOHOST
 78	---help---
 79	  Broadcom 43xx device support for Soft-MAC SDIO devices.
 80
 81	  With this config option you can drive Soft-MAC b43 cards with a
 82	  Secure Digital I/O interface.
 83	  This includes the WLAN daughter card found on the Nintendo Wii
 84	  video game console.
 85	  Note that this does not support Broadcom 43xx Full-MAC devices.
 86
 87	  It's safe to select Y here, even if you don't have a B43 SDIO device.
 88
 89	  If unsure, say N.

 91#Data transfers to the device via PIO. We want it as a fallback even
 92# if we can do DMA.

106	bool "Support for 802.11n (N-PHY) devices"
107	depends on B43
108	default y
109	---help---
110	  Support for the N-PHY.
111
112	  This enables support for devices with N-PHY.
113
114	  Say N if you expect high stability and performance. Saying Y will not
115	  affect other devices support and may provide support for basic needs.
116
117config B43_PHY_LP
118	bool "Support for low-power (LP-PHY) devices"
119	depends on B43
120	default y
121	---help---
122	  Support for the LP-PHY.
123	  The LP-PHY is a low-power PHY built into some notebooks
124	  and embedded devices. It supports 802.11a/b/g
125	  (802.11a support is optional, and currently disabled).
126
127config B43_PHY_HT
128	bool "Support for HT-PHY (high throughput) devices"
129	depends on B43 && B43_BCMA
130	default y
131	---help---
132	  Support for the HT-PHY.
133
134	  Enables support for BCM4331 and possibly other chipsets with that PHY.
135
136config B43_PHY_LCN
137	bool "Support for LCN-PHY devices (BROKEN)"
138	depends on B43 && BROKEN
139	---help---
140	  Support for the LCN-PHY.
141
142	  Say N, this is BROKEN and crashes driver.
143
144# This config option automatically enables b43 LEDS support,
145# if it's possible.
146config B43_LEDS

151# This config option automatically enables b43 HW-RNG support,
152# if the HW-RNG core is enabled.
153config B43_HWRNG
154	bool
155	depends on B43 && (HW_RANDOM = y || HW_RANDOM = B43)
156	default y
157
158config B43_DEBUG
159	bool "Broadcom 43xx debugging"
160	depends on B43
161	---help---
162	  Broadcom 43xx debugging.
163
164	  This adds additional runtime sanity checks and statistics to the driver.
165	  These checks and statistics might be expensive and hurt the runtime
166	  performance of your system.
167	  This also adds the b43 debugfs interface.
168
169	  Do not enable this, unless you are debugging the driver.
170
171	  Say N, if you are a distributor or user building a release kernel
172	  for production use.
173	  Only say Y, if you are debugging a problem in the b43 driver sourcecode.
