ssb bus can be found on various "host" devices like PCI/PCMCIA/SDIO. Every ssb bus contains cores AKA devices. The main idea is to have ssb driver scan/initialize bus and register ready-to-use cores. This way ssb drivers can operate on a single core mostly ignoring underlaying details. For some reason PCMCIA support was split between ssb and b43. We got PCMCIA host device probing in b43, then bus scanning in ssb and then wireless core probing back in b43. The truth is it's very unlikely we will ever see PCMCIA ssb device with no 802.11 core but I still don't see any advantage of the current architecture. With proposed change we get the same functionality with a simpler architecture, less Kconfig symbols, one killed EXPORT and hopefully cleaner b43. Since b43 supports both: ssb & bcma I prefer to keep ssb specific code in ssb driver. This mostly moves code from b43's pcmcia.c to bridge_pcmcia_80211.c. We already use similar solution with b43_pci_bridge.c. I didn't use "b43" in name of this new file as in theory any driver can operate on wireless core.

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