Subject: blackfin and USB

Hi there

I am trying to configure kernel for Blackfin (BF533). I cannot enable USB driver for host (any) till i enable PCI (and in fact there is no PCI on blackfin).
Even if i enable it, i will have:

CC drivers/pci/access.o
CC drivers/pci/bus.o
CC drivers/pci/probe.o
drivers/pci/probe.c: In function 'pci_scan_slot':
drivers/pci/probe.c:1024: error: implicit declaration of function 'pcibios_scan_all_fns'

I guess there must be a way to enable devices without enabling PCI (logically correct), or it must not call this function.

I am using 2.6.26 vanilla kernel.
Btw is networking works on Blackfin with vanilla?

"networking" works. specific driver is up to you to see if it works.
