The previous generation (RK3566 and RK3568) is affected by the 32
bit issue as well as the shareability issue. I'm currently focusing
on the RK3588 and that's the only Rockchip platform I have on my
desk. Missing PCIe support is a lot more critical on RK3588, because
multiple board designers decided to use a 2.5G PCIe network card
instead of using the 1G network MAC from the SoC.

Anyways, I will try to help out with RK356x once I find some time.
