I was able to build weston/wayland with meta-raspberrypi, for
the Tizen distro:
	http://blogs.s-osg.org/bringing-tizen-to-a-raspberry-pi-2-near-you/

I had to apply a few patches to make it work on both Tizen and
meta-raspberrypi. The forks are at:
	http://git.s-osg.org/

The current version there is actually disabling EGL. Enabling
it seems to be possible, but we're still trying to make it work
(it compiles fine, though, so I think we're close).

Once done, my plan is to work on porting the patches back to
meta-raspberrypi (and tizen-distro).

The egl-enabled version (with doesn't run, currently), is at the
"devel" branch at both git trees.

I hope that helps.

Regards,
Mauro
