Ooh it's nice if people are able to re-use the work Openmoko funded there!

If you do
make ARCH=arm menuconfig
and have a look in "device drivers", "Plug and Play support" should be
the fifth guy down, make sure he is selected like [*]. I guess for
xscale it is still ARCH=arm. In the Kconfig for it at
./drivers/pnp/Kconfig
it says
menuconfig PNP
bool "Plug and Play support"
depends on HAS_IOMEM
depends on ISA || ACPI || SDIO <========
so make sure you enabled the SDIO stack that is part of the Atheros
driver in your config too. Seems to be
CONFIG_SDIO=y
CONFIG_SDIO_AR6000_WLAN=y
Be aware though this driver is sensitive to the firmware version you
have on your physical wireless device, IIRC we use some magic "89"
firmware, but I don't know much about it.
