Ard,
PcdPciIoTranslationIsEnabled is only use for whether to trigger the Ffio read
or write, it seem that only x86 or x64 need them, not others.
When I was submitted the patch V2, CpuIo2Dxe was private to LoongArch, just
like Arm and RISC-V. Gerd recommended finding a better place for
ArmPciCpuIo2Dxe so that other ARCH can easily use it. And then I found the
UefiCpuPkg/CpuIo2Dxe might be able to accommodate the MMIO methods, so I merged
them togeter in this change.
I think it makes sense to have a shared implementation under
UefiCpuPkg or even MdeModulePkg. But merging it with the x86
implementation using function pointers that are dereferenced at
runtime seems unnecessary to me.
So what do you suggest? Write some new functions to handle the MMIO
method under the CpuIo2Dxe?
My preference would be to put this into MdeModulePkg, but Ray may have
a different view.
Let's wait for Ray together. :)
