>Environment:
System: NetBSD mirage 5.99.30 hpcarm on W-ZERO3 WS003SH
Architecture: arm
Machine: hpcarm, but probably affects more ports
>Description:
ral(4) requires MI src/sys/dev/rt2661.c, but it includes <dev/pci/pcidevs.h>
to refer PCI device IDs for ral(4) at pci(4).
The pcidevs.h includes <machine/pci_machpdep.h> which is not provided
on ports that don't have PCI, so ral(4) at usb(4) doesn't compile
on such ports.

>How-To-Repeat:
Configure ral(4) at usb(4) on hpcarm (or other PXA27x based ports
without PCI) and build a kernel.

>Fix:
 - move PCI dependent code from MI source to a bus dependent hook function?
 - define and use ral(4) own IDs instead of IDs from pcidevs.h?
