the following patch was just integrated into master: commit c95bfbd09fa2b2483fe8f48dc99848084207b9b3 Author: Rudolf Marek <r.marek@assembler.cz> Date: Sun Nov 25 19:55:01 2012 +0100 Add support for extended PCI config space via 0xcf8 Some chipsets allows on request an access to extended PCI config space 0 - 4096. Lets add them to the decoder. There is no generic limitation for number of busses, but this mechanism is used as the backdoor to chipset extended PCI regs.
