Broadcom 43xx device support for Soft-MAC SDIO devices.
With this config option you can drive Soft-MAC b43 cards with a
Secure Digital I/O interface.
This includes the WLAN daughter card found on the Nintendo Wii
video game console.
Note that this does not support Broadcom 43xx Full-MAC devices.
It's safe to select Y here, even if you don't have a B43 SDIO device.
