Patch Set 1: Code-Review+1
Hmm. Since this is a router board nobody cared about graphics... Without the GPU and the converter, there is not much I can do. At least I can say that the BottomIO can be moved if there is not enough space for devices, so it should be ok. From Kconfig help of the BOTTOMIO_POSITION from binaryPI:
If PCI peripherals with big BARs are connected to the system the bottom of the IO must be decreased to allocate such devices.
Please test to confirm there are no downsides of this change for a bare APU1 (without a discrete GPU). The same change has been successfully tested on fam15h and fam16h boards that I have (A88XM-E and AM1I-A), would be nice to know that it doesn't break the things for fam14h as well.
