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?
