[Buildroot] [PATCH v3 0/4] beaglebone: u-boot and kernel updates

[Anders Darander]

Hi,

This patch series upgrades the kernel for the BeagleBone to 3.12.

The 3.12 kernel is taken from TI's own repo, and the actual branch/commit used
is the latest  used in their own BSP (see meta-ti for OpenEmbedded / Yocto).

I've tried to keep the defconfig as close to the 3.8 version as possible. Though, 
it's quite likely that some added configuration could have been removed.

It's only been tested on a BeagleBone White, using my usual NFS-root setup.

The PM FW in am33x-cm3 has been update to keep it in sync with the kernel.
The revision used is taken from meta-ti.

There's also an update to the latest U-Boot, and as a followup to that patch,
a change to zImage instead of uImage. (As that's the current default in 
U-Boot).

Cheers,
Anders

Changelog: 
v2 -> v3:
        * Update the kernel and am33x-pm to the latest sha1's.

v1 -> v2: 
        * update the git sha1 to the latest applied to the meta-ti repo.

  am33x-cm3: update to latest version

[Buildroot] [PATCH v3 1/4] beaglebone: update to TI 3.12 kernel

[Anders Darander]

Git repo version is taken from meta-ti.
It's a 3.12.9 kernel with TI's own patches on top.

The defconfig has been kept rather close to our old defconfig.
The kernel has been boot-tested using an NFS-root.

Apart from the kernel change, the linux headers has also been
updated from 3.8.12 to 3.12.9.

[Buildroot] [PATCH v3 2/4] am33x-cm3: update to latest version

[Anders Darander]

This goes hand-in-hand with the kernel update.
The version is taken from meta-ti.

The new kernel version, 3.12, requires a newer PM FW.

This should correspond to v05.00.00.02, though that tag
has not been pushed...

[Buildroot] [PATCH v3 3/4] beaglebone: update to latest U-Boot

[Anders Darander]

Update to the default version of U-Boot, at this time 2013.10.

Tested with an old uEnv.txt (i.e. using uImage) and with the
currently prefered zImage.

You should keep these lines and just change it to "2013.10".

The reason is that if you remove these lines, then what the defconfig
means is "use whatever default version Buildroot has". This is not the
behavior what we want for defconfig, since we want them to be
reproducible, as we have no guarantee that newer U-Boot versions will
continue to work for a given platform.

I really knew this...

I'll respin the patches, likely on Monday morning. Hopefully I can also change the am33x-cm3 patch back to use a git tag instead oh a SHA1 then, at least of TI pushes that tag. 

Do you have any comment on Ryan's suggestion to squash the change to zImage into this patch? 

Cheers, 
Anders

I would suggest merging this change with your previous patch -
"beaglebone: update to latest U-Boot" - because the upgrading of
u-boot is what is causing the change to zImage.

Thanks,
-Ryan

What do other dev's think about this? It doesn't really matter to me if I squash then or not. 

My reasoning was that of you kept the old U-Boot environment, the new U-Boot works with a uImage. That's basically why I kept it as separate patches.

Hum, I believe that's a good point. Then maybe for "clarity" it's
better to keep them separate. This way, an user looking through the
changes on the beaglebone_defconfig will more likely see this change.

My original thinking was since the default U-Boot environment (in the
board file) was being changed to use zImage with version bump, you
should change the kernel image to be zImage in the same patch. I did
not think of this use case when I quickly looked over this change. So
I'm OK with keeping this separate.

Thanks,
