Yes, I adapted the code to used in LinuxBIOS, including CAR stage code and RAM satge code.
I didn't have debug cable plugged yet.
Even if you did it wouldn't work right now. My initial version does initialize the ehci properly so it won't find any usb devices. I almost have that fixed, but it looks like for the usb device reset I need a usable delay function, so I can delay 50ms. Grr...
BTW in kernel earlyprintk or prink, you could use read_pci_config/write_pci_config before PCI system is loaded.
Yep thanks that seems to be working. Now I just need to find an early delay and I can try this mess out!
