board: add support for Intel Galileo Gen 2

Delta's from v3:-

* mdev hack replaced with init.d script.
* SD card creation shell script replaced with genimage config.
* Kernel config reduced to minimal size.
* Introduce rootfs overlay to reduce post-build.sh logic
* Fixed typos

Board support package includes:-

* Toplevel build root configuration
* Github based 3.8.7 Kernel
* Upstream 3.8.7
* Linux 3.8.7 Kernel Driver Patches
* Linux 3.8.7 configuration
* Grub configuration
* Init Script to load modules
* genimage config to create sdcard image.
* Patch to binutils to omit LOCK prefix

I was trying this patch series out, but running into some issues.

The major one is that if I create the "sdcard.img" using the defconfig, write it onto a card, and try to boot from it, I get this kernel panic as the result:

Is there anything I might be missing?
(Using a Gen2 board)

Can you add "rootwait" to your kernel command line?

Thanks,

I was trying this patch series out, but running into some issues.

The major one is that if I create the "sdcard.img" using the defconfig, write it onto a card, and try to boot from it, I get this kernel panic as the result:

Strange - an artifact of the speed of the SD cards perhaps? Need to add rootwait in grub.conf - me thinks.
