Hi, Robert,

Thanks!

> Two questions/remarks:

both of these are available from asm/io.h on all architectures?

Yes, but here they're special macros for USB register access. You can
refer to the newest usb-git tree of Markus.

from PCI address space to processor address space.

Does current codes not run well on your system? It's in U-boot now. The
address in the PCI bar is processor address.

Cheers!
Wei.
