KVM has a bug that prevents using page tables in the ROM if the ROM region utilizes the KVM READONLY memory feature. Therefore, we avoid using page tables stored in the ROM. Since OVMF doesn't require memory initialization, we just build page table entries in RAM at 0x80000 very early in the OVMF boot process. This address is just after the 'temp RAM' which is set up by the SEC module. Currently we only set up 4GB of page tables for OVMF's PEI, but DxeIpl will build identity mapped page tables that cover all of the available processor physical address space.
