  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.

 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.

 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.

109	  Support for the N-PHY.
110
111	  This enables support for devices with N-PHY.
112
113	  Say N if you expect high stability and performance. Saying Y will not
114	  affect other devices support and may provide support for basic needs.
115
116config B43_PHY_LP
117	bool "Support for low-power (LP-PHY) devices (EXPERIMENTAL)"
118	depends on B43 && EXPERIMENTAL
119	default y
120	---help---
121	  Support for the LP-PHY.
122	  The LP-PHY is a low-power PHY built into some notebooks
123	  and embedded devices. It supports 802.11a/g
124	  (802.11a support is optional, and currently disabled).
125

160	  Broadcom 43xx debugging.
161
162	  This adds additional runtime sanity checks and statistics to the driver.
163	  These checks and statistics might me expensive and hurt runtime performance
164	  of your system.
165	  This also adds the b43 debugfs interface.
166
167	  Do not enable this, unless you are debugging the driver.
168
169	  Say N, if you are a distributor or user building a release kernel
170	  for production use.
171	  Only say Y, if you are debugging a problem in the b43 driver sourcecode.
172
173config B43_FORCE_PIO
174	bool "Force usage of PIO instead of DMA"
175	depends on B43 && B43_DEBUG
176	---help---
177	  This will disable DMA and always enable PIO instead.
178
179	  Say N!
180	  This is only for debugging the PIO engine code. You do
181	  _NOT_ want to enable this.
