To help foster fast development, future releases of the Angstrom
Distribution that ships with BeagleBoard.org platforms (such as

effect of providing yet-another-BSP for BeagleBoard.org platforms,
collaboration in the mainline kernel and bootloaders that are the key
elements for the BSPs has made this possible and multiple goals for
the various BSPs has made it desirable.
The objectives for meta-beagleboard are:
1) Provide the best possible out-of-box-experience for BeagleBoard.org platforms
2) Enable as much add-on hardware as possible
3) Enable public contributions to extend the experience and hardware support
4) Deliver information to the BeagleBoard.org community regarding the
development status
The repository will be hosted at:

Great news! Will the kernel in this BSP be attempting to follow
mainline + public patches? I'm chomping at the bit for an easy way
to build a tested DT kernel with recent patches.
Jack,
Here's a little bit of information to help you and others understand the
situation a bit better.
The beagleboard kernel recipe in meta-ti was already following mainline +
public patches. As of the beaglebone:
The mainline kernel team for am335x inside TI has been hard at work pushing
patches upstream for quite a while now. You can see significant improvements
in the mainline kernel already, even in 3.6, when it comes to supporting
am335x. But the goal is to have most, if not all, of the features in place by
the time Linus releases 3.8 kernel. According to the schedule, that is around
the end of this year or early next year.
Due to limited resources of testing and validation, the integration team
decided to not spend time on kernels between the last staging (i.e. PSP) 3.2
kernel and 3.8, when everything is available in mainline.
Unfortunately, that does not work for BeagleBoard.org and Koen needs mainline
support sooner, integrating incomplete 3.6 and 3.7 with the work-in-progress
patches. That's one of the points behind creating meta-beagleboard layer.
That said, meta-ti will also be switching to the mainline kernel once it is
available, i.e. with 3.8 release. It's just that meta-beagleboard gets there
sooner... :)
Perfect, thank you Denys. That also explains why the PSP releases for
the BBone haven't been very forthcoming. I have been watching the
mainline patches come in but didn't realise that TI were heading for 3.8
'full' support. I will be looking forward to it, I can almost taste that
eDMA
Cheers,
