Is it enough to build Open-Source drivers for its VPU ?
Yes. There's even two v4l drivers in progress for the coda9xx vpu:

These still need closed source firmware for the bit processor, but the ARM side is open.
The VPU block is from Chips and media:

Has the GPU been reverse-engineered?
YES. https://github.com/laanwj/etna_viv/wiki
