Subject:   Correct way to get hold of a isab

Hi,


I've written a GPIO driver for the National Geode SCx200 processors.
While I was developing I added the following line in isab_match()
(sys/pci/pcisupport.c) so it wouldn't be identified as a isa-bridge.


isab_match(device_t dev)
{
	switch(pci_get_devid(dev)) {

	.
	.
	.

		/* National Geode SCx200's ISA and GPIO/LPC bridge,
		   needs to be free so we can claim it later from
		   the GPIO-driver.  */

		case 0x0500100b:
			return(NULL);
		}
	
	.
	.
	.
}

This do work, but I guess this isn't the correct way, how should it 
be done?


TIA,
/Alexander
