BPI-W2 Kernel 5.9.0-rc5-next

Things are getting more clear, after digging through tons of docs I managed to boot up the self compiled mainline Linux, needed to hack around some stuff but at least it finally loads and boots.

The Kernel craps out because I didn’t preloaded any valid intird in uboot, but this is easily mitigated. Initialization of this board is quite complicated (at least from my perspective)

@bpi: Where can I get some real RTD1295/96 pdf documentation on device initialisation, especially parts of tee/audio firmware, audio/gpu blobs, if any?

More info soon. Anyone any tips?
