// Intel HD3000 or HD4000 is used. For example, on GA-H81N-D2H there is a single 1 GB descriptor:
// 000000009F800000-00000000DF9FFFFF 0000000000040200 8000000000000000
//
// All known boot.efi starting from at least 10.5.8 properly handle this flag and do not assign
// virtual addresses to reserved descriptors. However, our legacy code had a bug, and did not
// check for EfiReservedMemoryType. Therefore it replaced such entries by EfiMemoryMappedIO
// to "prevent" boot.efi relocations.
// Older EfiBoot (from 10.4.x) assigns virtual addresses to all descriptors containing
// EFI_MEMORY_RUNTIME flag, including ones with EfiReservedMemoryType. Starting with 10.5
// this is fixed, and virtual addresses are not assigned to reserved descriptors.
// We might eventually need to add some workaround to prevent exceeding virtual address space
// in EfiBoot from 10.4 by dropping the EFI_MEMORY_RUNTIME flag.
