This function returns true if the device passed to it is attached to an
ICH-ICH4. If the chip is not attached to an ICH, or is attached to an ICH5
or newer, it returns false.
This function determines which bridge it is attached to by scaning the pci
bus looking for bridge chips (hdr_type=1). When a bridge chip is detected,
the bridge's subordinate's secondary bus number is compared with this
devices bus number. If they match, then the device is attached to this
bridge. The bridge's device id is compared to a list of known device ids for
ICH-ICH4. Since many older ICH's (ICH2-ICH7) share the same device id, the
chip revision must also be checked to determine if the chip is older than an
ICH5.
To scan the bus, one of two functions is used depending on the kernel
version. For 2.4 kernels, the pci_find_device function is used. This
function has been depricated in the 2.6 kernel and replaced with the
fucntion pci_get_device. The macro walk_pci_bus determines which function to
use when the driver is built.
