Replying with real email client :-)

Err should have been RK3588 :-)

A much needed upgrade for the MNT Reform laptop. i.MX8M is a bit slow for 
use in a consumer device for general computing.

I don't know. The plans linked is above what I want to do, if I understand 
it right. I come from RISC OS lands , and in our rom we have EHCI,OHCI and 
XHCI in seperate controller drivers. This all connects to what we call 
USBDriver which is the main USB stack.

In Genode I would like to have something similar. It makes it very easy to 
bring up on new platforms. In my case, Rockchip, I start USB ( power/phy) 
from U-Boot. After that I only need to assign address and irq to the 
controller driver. If Genode doesn't have native controller drivers at all 
(in pc port) ( sorry haven't checked yet), I could try to bring in 
controler drivers from BSD.

Happy end of 2023!
