Not much on my side, apart that it is a bit annoying that some of the support is actually an almost exact copy of the arm code (PCI being a striking example). It would have been nice to see some effort to make the code common, although it isn't a blocker on my side. Thanks, M.

The code sharing between ARM and RISC-V support needs to be improved. We have more stuff to be added after this series so I will prioritize code sharing.
