I've been trying to put the VME match/attach routines into grfabs_et.c as
a probe routine.  In the match/attach routines for the other VME devices
(e.g. le, leo), the functions are passed :

	et_vme_match (pdp, cfp, auxp)
		struct device *pdp, *cfp;
		void *auxp.

and have :

	struct vme_attach_args *va = auxp;

Then the bus tags are found from :

	va->va_iot;
	va->va_memt;

However, the PCI probe in grfabs_et.c doesn't have this.  The PCI tags
are created using :

	pci_make_tag (NULL, 0, n, 0);

What do I need to do to find/create the VME bus tags?  I think I need these
so that I can do :

	bus_space_map (memt, maddr, msize, 0, &memh);
	bus_space_map (iot, ioaddr, iosize, 0, &ioh);

before probing the addresses.

Thanks,

J
