Hi,
I'm trying to write a driver for a serial card - it is fairly simple,
but I'm having trouble with some conversions from the Linux driver :)
In the Linux driver there is stuff like ->
if ((rc = pcibios_read_config_byte(bus, dev_fn, PCI_DC_SIO_PORT,
&nport)) != PCIBIOS_SUCCESSFUL) break;
And I think the equiv would be ->
tmp = pci_read_config(dev, PCI_DC_SIO_PORT, /*bytes*/1);
printf("pccom: number of ports - %d\n", tmp);
However this just ends up printing 0.
(PCI_DC_SIO_PORT is 0x2f)
