[Buildroot] [PATCH v4 0/4] Upgrade BeagleBone kernel to 3.8

[Buildroot] [PATCH v4 0/4] Upgrade BeagleBone kernel to 3.8

[Anders Darander]

Hi,

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 use of the Cortex-A8 compilerc for the Cortex M-3 code, has been verified
to work using the buildroot compiler. TI is using the same setup in their BSP
built using Yocto Project (i.e. use the A8 compiler for thde M3 FW).

The last patch in the series (0004-beaglebone-enable-NFS-root.patch) is not
necessary; it's only my preferred way of testing.

Cheers,
Anders

V4: * Fix a similar typo. (don't work when you're tired...)

V3: * Fix a typa in am33x-cm3.mk.

V2: 
    * Squashed the reduction of the kernel config into the first commit (the
      actual upgrade commit).

    * Running format patch with -M10 instead of -M to detect the rename.

    * Fixes in the am33x-cm3 package:
      * Changed to tag (instead of SHA1), changed to http instead of git
        protocol. 

      * Renamed the license.
      * Install the init script in a _INIT_SYSV hook.

[Buildroot] [PATCH v4 1/4] beaglebone: update to linux 3.8

[Anders Darander]

As the beaglebone support is mainlined, there's no support for the old
board setup files, and the only supported run-time configuration is through
the device tree.

We're also setting the kernel headers to follow the 3.8 series.

[Buildroot] [PATCH v4 1/4] beaglebone: update to linux 3.8

It's afaik only for suspend/resume handling (E.G. low power).

SoC specific packages like this should depend on BR2_arm to not clutter

I've added 'on am335x', otherwise it isn't clear that this is for
am335x.

I've also added the git location as upstream URL.

And renamed here as well.

These lines are very long, so I've word wrapped them.

Committed to next with these changes, thanks.

Well, at least on my board will hang if I issue `reboot` without having
loaded the FW...
Though, from the descriptions in the repo, I'd also have assumed that it
was only needed for the low power modes.

But that's mostly nitpicking, I guess...

Cheers,
Anders

Perhaps with the TI kernel which has the suspend stuff integrated. It is
not (yet) in mainline, and mainline reboots fine without it.

Indeed.
