Thanks for the note.

This address is specific to the BSP and a normal user should not be configuring it. For all the BSPs, the PCI addresses are hard coded values, as they used to be. This can't be configured without changing some of the memory mappings. The corresponding VME window address is configurable and I have added an option for that to be configured.
