Can you point me in the right direction? What I've done so far is go into
src/mainboard/via/epiam  (cloned from epia)
I regenerated irq_tables.c by flashing with award bios, booting up the board,
then running the getpir.c utility from version1 (note this utility isn't
present in version 2).

It is still calling the 8231 code. Is the interrupt stuff in with the
southbridge? Or is it the northbridge?

v2 epia-m progress [PMX:#]

[ron minnich]

interrupts are set up in the mainboard (since that determines everything).

Following earlier work i erroneously put this in 
src/southbridge/vt8231/vt8231.c, which is wrong. I have to move this code 
to src/mainboard/via/epia/mainboard.c

here's the code

/* PIRQ init
 */
void pci_assign_irqs(unsigned bus, unsigned slot, const unsigned char 
pIntAtoD[4]);

static const unsigned char southbridgeIrqs[4] = { 11, 5, 10, 12 };
static const unsigned char enetIrqs[4] = { 11, 5, 10, 12 };
static const unsigned char slotIrqs[4] = { 5, 10, 12, 11 };

/*
        Our IDSEL mappings are as follows
        PCI slot is AD31          (device 15) (00:14.0)
        Southbridge is AD28       (device 12) (00:11.0)
*/
static void pci_routing_fixup(void)
{
        device_t dev;

dev = dev_find_device(PCI_VENDOR_ID_VIA, PCI_DEVICE_ID_VIA_8231, 
0);
        printk_info("%s: dev is %p\n", __FUNCTION__, dev);
        if (dev) {
                /* initialize PCI interupts - these assignments depend
                   on the PCB routing of PINTA-D

PINTA = IRQ11
                   PINTB = IRQ5
                   PINTC = IRQ10
                   PINTD = IRQ12

                pci_write_config8(dev, 0x57, 0xc0);
        }

// Standard southbridge components
        printk_info("setting southbridge\n");
