Hi,

(I'm resending this series from a subscribed address).

This patch series upgrades the kernel for the BeagleBone to 3.8.

The 3.8 kernel is taken from TI's own repo, and the actual branch/commit used
are the same as currently being used in their own BSP (see meta-ti for
OpenEmbedded / Yocto).

As the BB support is being mainlined, the old board-setup has been removed,
thus the 3.8 kernel requires the use of a device tree. (A DTS, am33x-bone.dts
is included in the kernel).

The new package, am33x-cm3, consists of the FW blob for the Cortex M3 on the
BB that handles the power management of the board. Without this firmware
loaded, even a simple `reboot` won't succeed. In the old 3.2 kernel, this was
compiled in as a part of the kernel, however, in the 3.8 kernel, it has to be
loaded during the runtime.

The last patch in the series (0005-beaglebone-enable-NFS-root.patch) is not
necessary; it's only my preferred way of testing.

Cheers,
Anders
