Correct way to get hold of a isab

[Alexander Funcke]

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
