6.6-stable review patch. If anyone has any objections, please let me know.

In a future patch HAS_IOPORT=n will result in inb()/outb() and friends not being declared. In the pci-quirks case the I/O port acceses are used in the quirks for several AMD south bridges, Add a config option for the AMD quirks to depend on HAS_IOPORT and #ifdef the quirk code.

There is no harm in backporting this one to 6.6, but there is no need either since it is only a preparation for the coming changes to asm/io.h.
Like the PCI quirks patch, I wouldn't backport it at all. If you do want to keep it, be careful about backporting it to older kernels, as it depends on fcbfe8121a45 ("Kconfig: introduce HAS_IOPORT option and select it as necessary") from linux-6.4.
Agreed, I've dropped all of these now, thanks.
