In addition:

Attached is "Vivante GC320 Technical Reference Manual V1.0_A", this used to be
on the Vivante site a long time ago (I think it was some cooporation with TI).
It's incomplete but some parts could be useful.

There's also some 2D examples in etnaviv (no guarantee any of this still builds):
