PCI Driver - Read/Write to Base Address

Hey everyone,

I am trying to read and write to a PCI Base Address. Right now, I have:

static int rpm_probe(struct pci_dev *dev, const struct pci_device_id
*id)
{
pci_enable_device(dev);

u32 BaseAddress0;
pci_read_config_dword(dev, PCI_BASE_ADDRESS_0, &BaseAddress0);
printk(KERN_ALERT "PCI_BASE_ADDRESS_0: %x\n", BaseAddress0);
}


To read/write to that particular base address, do we just need to add
the following lines:
u32 BaseAddress0data;
pci_read_config_dword(dev, BaseAddress0, &BaseAddress0data);
pci_write_config_dword(dev, BaseAddress0, 0xFF000000);

or is there another pci function that I should use?
