[Qemu-devel] [PATCH v2 02/18] i386/acpi-build: allow SSDT to operate on 64 bit |

Only 512M is left for MMIO below 4G and that are used by PCI, BIOS etc.
Other components also reserve regions from their internal usage, e.g,
[0xFED00000, 0xFED00000 + 0x400) is reserved for HPET
Switch SSDT to 64 bit to use the huge free room above 4G. In the later
patches, we will dynamical allocate free space within this region which
is used by NVDIMM _DSM method
