Currently several DXE crash due to invalid memory resource settings. The PciHostBridgeDxe which expects the MMCONF and PCI Aperature to be EfiMemoryMappedIO, but currently those regions are (partly) mapped as EfiReservedMemoryType. coreboot and slimbootloader provide an e820 compatible memory map, which doesn't work well with EDK2 as the e820 spec is missing MMIO regions. In e820 'reserved' could either mean "DRAM used by boot firmware" or "MMIO in use and not detectable by OS". Guess Top of lower usable DRAM (TOLUD) by walking the bootloader provided memory ranges. Memory types of RAM, ACPI and ACPI NVS below 4 GiB are used to increment TOLUD and reserved memory ranges touching TOLUD at the base are also assumed to be reserved DRAM, which increment TOLUD. Then mark everything reserved below TOLUD as EfiReservedMemoryType and everything reserved above TOLUD as EfiMemoryMappedIO. This fixes assertions seen in PciHostBridgeDxe.
