Intel^® EP80579 Integrated Processor
lies in the standard PCI configuration, status, and capability registers that PCI requires
which materialize only in PCI configuration space. The AIOC devices that lie behind the
bridge allocate by either the BIOS or OS to their regions of address and I/O space
within a contiguous region of address space that the bridge claims. It is assumed that
system software configures the aperture for the bridge to be large enough to cover all
of the address space that the devices behind the bridge request.
The remainder of this section summarizes the device tree that the EP80579
implements. This summary includes a mapping between PCI devices and the EP80579
blocks along with the value of the device ID, class code, and a summary of the
resources (i.e., registers, memory, etc.) that each device requests.
Table 3-9 summarizes the PCI devices that the IMCH and IICH materialize.
