NAK - mmio is an iomap so writel and readl are the wrong things to use
The patch is consistent with the rest of the driver.
You are welcome to submit a patch to convert ahci to using ioremap.

You could just flip the relevant function to use ioread while you are
tidying it up, instead of spreading new bugs into the code.

No, as I just noted above, the proper fix for this driver is to use ioremap rather than pci_iomap.

Adding support to ahci for legacy PIO is completely pointless.
