Bug Description

Mathieu P:

I got just wifi going on a ubuntu build but it was certainly not without
efforts. I can assert that it works for both V5 and V11 board.

Long story short, wifi support (and BT as well) is broken on IK kernel
3.1 and 3.2.

If you download today's hwpack [1] and rootfs [2] you get all the needed
components (driver and firmware) but the BT stack isn't starting properly.

To get something working you'll have to clone the last available 3.0
branch we have on IK [3] and compile it using 'make u8500_defconfig',
followed by 'uImage' and 'modules'.

From there the trick is do a 'make modules_install
INSTALL_MOD_PATH=/media/rootfs' to get the needed dependencies for
modprobe to work properly.

See you on IRC,

Attaching a log from bootup with 3.2.0-1000-ux500, indicating that while bluetooth came up the wlan module failed on init.

Looks like cw1200_wlan speaks through SDIO interface, but setting up fails with:

[ 17.151428] mmci-pl18x sdi1: unsupported alginment (0xcd6)

whatever that means.
