Hmm. When I wrote Doug Rabson about newbus months ago, he gave me that
part of code:
rid = 0x10; /* offset of pci mapping register - check your docs */
res = bus_alloc_resource(dev, SYS_RES_IOPORTS, &rid, 0, ~0, 1,
RF_ACTIVE);
st = rman_get_bustag(res);
sh = rman_get_bushandle(res);
This "offset of the pci mapping register" is quite confusing for me
then.
