  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.

 29 config B43_BCMA
 30         bool "Support for BCMA bus"
 31         depends on B43 && (BCMA = y || BCMA = B43)
 32         default y

 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 
 74 config B43_SDIO

 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.

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 
117 config 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 
127 config 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 
136 config 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.
146 config B43_LEDS
147         bool
148         depends on B43 && MAC80211_LEDS && (LEDS_CLASS = y || LEDS_CLASS = B43)
149         default y

152 # if the HW-RNG core is enabled.
153 config B43_HWRNG
154         bool
155         depends on B43 && (HW_RANDOM = y || HW_RANDOM = B43)
156         default y
157 
158 config 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.
