Drivers and such things (the rk3588 port)

Hello,

1, Is there a generic ehci and xhci driver that I can pass my initialised controller address and irq number to? 2, I need to map a physical address and the other way , I need the physical address of a buffer.

I don't have my older projects online (we have moved and my networking infrastructure is very limited), and I don't remember how I did it for starting riscos on the second core. That mapped a buffer to physical address,

If question 1 is a positive answer , I have usb working ( I hope) If question 2 "can be done" I have graphics, although not in a driver yet.
