These are the PPC440SPe boards Yucca & Katmai and the 405EX board Kilauea. This dynamic configuration is done via the "pcie_mode" environement variable. This variable can be set to "EP" or "RP" for endpoint or rootpoint mode. Multiple values can be joined via the ":" delimiter. Here an example: pcie_mode=RP:EP:EP This way, PCIe port 0 will be configured as rootpoint, PCIe port 1 and 2 as endpoint.
