Hi
Could someone explain the need for five (5) different versions of
root_complex, which appears to be just a logical container with
no real hw to control?
northbridge/amd/amdfam10/root_complex
northbridge/amd/agesa/family14/root_complex
northbridge/amd/agesa/family12/root_complex
northbridge/amd/agesa/family10/root_complex
northbridge/amd/amdk8/root_complex
Could you not have just one drivers/generic/root_complex?
In my opinion, the current devicetree.cb practice of placing
the "chip northbridge/x/x" line outside the pci_domain is mis-leading on
boards without the root_complex.
Looking at the amd/persimmon I was also confused about the multiple
instances of the "chip northbridge/amd/agesa/family14" line.
Thanks,
Kyösti
