This changelog is missing some key information:
- how did you find the bug (by chance via code review or did you see
some actual badness?)
- what practical effect (if any) did you see from this patch?
- what practical effect (if any) do you expect others to see from
this patch?
I suspect this patch is only for completeness/correctness but has no
practical effect - but that's a guess.
My guess would be that seabios tried to lay out the BARs and had
trouble fitting a 16k pio bar in the small PCI pio region.
Sasha? IIRC this fixed some issue with David's out-of-tree PCI driver?
