The POWER PHBs don't support legacy I/O cycle accesses, so the above messages are expected (and harmless). Every modern device falls back to MMIO access, which is actually required in the PCIe specifications -- I/O access is only available at all due to legacy Intel 80x86 (!) compatibility requirements.

Is the driver failing in any other way? Failing to map MMIO or otherwise printing any messages about BAR size? Is there any chance the Nouveau developers have coded the driver to use only the legacy I/O accesses instead of MMIO?

bernie:
No, for me the driver is working fine despite the failures shown in dmesg. I only posted it as requested by carlosgonz. Thanks for the explanation though, good to know that it's nothing to worry about.

Good to hear, thank you for the update!

carlosgonz:
Thank you RCS for let to know us that the output is normal.

I was just worried when i noticed those PCI outputs failed. I was just testing a Nvidia card and started trying out SuperTuxKart and saw that the performance was terrible, only 6fps at maximum performance in STK. So i started looking into what could be wrong and saw those pci failed in dmesg which make me to think that Petitboot it could be interfering with Nouveau as Nouveau doesn't support 65k.
The Nouveau and Nvidia card work OK, however performance is not much good as i using nvidia k620. Recently Mesa 25.1 added support to maxwell-v1 to use the driver zink, so i hope to get better performance when i got testing.

The other question i have to RCS is why do those PCI io-failed appear even if i remove the Nvidia card?

thank you bernie for sharing ur output which is same like me.
