From: Peter Daifuku <pdaifuku@xxxxxxxxxx>
The 16 chunks of 64 KiB that need to be stitched together to make up the
configuration space for one bus (1 MiB) are located 24 bits (== 16 MiB)
apart in physical address space. This is determined by the start of the
extended register field (bits 24-27) in the physical mapping.
