BaseTools: Bootable NVDIMM namespaces
Provided a mechanism for UEFI FW to identify and hand off bootable
NVDIMM namespaces to the OS by standardizing the EFI device path.
EFI device path for physical NVDIMM devices changed from an ACPI
_ADR device to an ACPI NVDIMM device for correctness.
(UEFI 2.8 mantis 1858)
