A given platform will either be able to use port IO, or it will need

to use MMIO translation. So a driver that can do both based on a PCD

is not very useful, it makes more sense to have two different drivers,

and the platform incorporates the one it can use.



Ok, I get it, I think you are more inclined to move the ArmCpuIo2Dxe to a new place and rename it, maybe: CpuMmio2Dxe, while some platforms choose the different CpuIo2 drvier by themselves when building FW, right?





Yes.

Ok, I agree. If there are no issues with Ray, I will adjust this patch in V5. I tund is move it under UefiCpuPkg and name it CpuMmio2Dxe, it will be in the same directory as CpuIo2Dxe, is that OK?

Ray, what do you think of this plan?
