Not arguing that. Just saying the other targets install the shared PCI header file as rtems/pci.h. if it is an enhanced compatible api, then it should be in the same place. 

The support libraries can compile but if there is no PCI on the board, then the PCI drivers will never get linked. So dead code in the library but that's no big deal. Cpukit just needs to be consistent and this has one architecture install a .h file in a unique place. It is wrong.
