MuRata WiFi Module with Marvell 88w8686

[claud_yu]

Hi , 

Currently I use wi2wi W2SW0001, I send Murata module
back. I still try to port the libertas driver to mx31.
Wi2Wi provide a SD card development card on wi2wi
website. I also try another 88w8686 driver from
project moblin (http://www.moblin.org/). The driver
should based on marvell SDIO driver. But the driver
still have some problem while firmware download.
