+Subject: [PATCH] ssb: pick PCMCIA host code support from b43 driver
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+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.
