Ignore this part, just didn't read carefully. This is about getting H264, VP8
and MPEG2 out of these extra cores of course. I still would like to know how we
will express the grouping of these four cores, so a driver can know they are
identical G1 cores and not bound to be time sliced with an H1 core like the
fifth one? I want to see a plan that will work and will not cause headache for
future work on fully utilizing the HW resources.
