Could you let me know which firmware you are using? If the difference is Madt table vGIC your pointed , they are the same. We changed the vGIC memory base address at very early design stage.

Thanks!

Ok. Thanks for pointing this out. I have informed our UEFI team about this.
They will check Internally and clarify.
