a problem about PCI initialization

Hi

I am debugging a board based on Sandpoint8245.

sandpoint8245.h has these defination:

(
#define PCI_ENET0_IOADDR 0x80000000
#define PCI_ENET0_MEMADDR 0x80000000
#define PCI_ENET1_IOADDR 0x81000000
#define PCI_ENET1_MEMADDR 0x81000000
#define PCI_ENET2_IOADDR 0x00000000
#define PCI_ENET2_MEMADDR 0x82000000
)

sandpoint.c has this defination:

static struct pci_config_table pci_sandpoint_config_table[] = {
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x0f, PCI_ANY_ID,
pci_cfgfunc_config_device, { PCI_ENET0_IOADDR,
PCI_ENET0_MEMADDR, PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER }},
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x10, PCI_ANY_ID,
pci_cfgfunc_config_device, { PCI_ENET1_IOADDR,
PCI_ENET1_MEMADDR, PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER }},
{ PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, PCI_ANY_ID, 0x18, PCI_ANY_ID,
pci_cfgfunc_config_device, { PCI_ENET2_IOADDR,
PCI_ENET2_MEMADDR,
PCI_COMMAND_MEMORY | PCI_COMMAND_MASTER }},
{ }
};

After calling pci_init() I output a value to address 0x80000000 and then CPU goes wront. I am so confused. If any of you can give me some hint, I will appreciate that very much!

Best Wishes
