I agree. It should allow a GSoC student to get straight into the actual 
graphics work without having to spend much time nursing though initial 
builds.

Anyhow I'm still doing the final checks but I think this is more or less 
ready to go. Fairly detailed README can be found here:

Regarding AOSP versus LCR: I have billed this an LCR port but I think 
the LCR releases are structured as AOSP supplied by .repo/manifests 
augmented by a Linaro-specific plus-pack in .repo/local_manifests. I can 
double check this if anyone needs this explicitly confirmed.

Anyhow I think this means the differences between LCR and AOSP are 
enumerated here:
