Hi all,

The GWG does have a LSK kernel branch with Mali support. (IE
accelerated graphics)

We haven't targeted Android as of yet but in the grand scheme things
should be reasonably close. Show can say for certain but we'd need a
rebase on linux-linaro-lsk-v3.10-android at a minimum.

I'm a little unclear how interesting the LSK android kernel is for the
Android team. One of my buffered questions for Khasim.

We do have requests from members to support / maintain Android on LSK. I would let Vishal look at integration, if we find any issues then we can jump in to fix specific issues.

Regards,

Khasim
