Hi Markus,
do you see a problem in passing a pointer to the gohci structure to
usb_cpu_init() or at least to usb_board_init()?
In order to get the base address of my PCI OHCI controller I first have to
find the device on the PCI bus. I think usb_board_init() is the right place
for this. But I need &gohci to pass it back to the usb driver.
Here's is what I mean:
diff --git a/drivers/usb_ohci.c b/drivers/usb_ohci.c
index c5e4c38..8afadd1 100644
--- a/drivers/usb_ohci.c
+++ b/drivers/usb_ohci.c
