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

Hi Arnout,

(Resending as I first sent from an unsubcribed email).

Well, the intention was to reduce it in the next patch, just to show how it
was derived. Though, I'll squash them in the next revision.

Hmm, strange, I was using -M, but I might have to tweak the threshold a
little bit. I'll look into that for the next revision.

Ok, then I guess that I should keep the old ordering, even though
savedefconfig have reordered some of them.?

I'm not sure if there's a tag available in this case.

Ok, so tags preferred if they exists... Good to know, I'll check it and
change it if there's a tag.

The list few years I've mainly been working with another build system,
where SHA1's are preferred over tags for network-less building.

I'll come back with a new series in a couple of days.

Thanks for the feedback!

Cheers,
Anders
