Defined Encrypted and Special Purpose resource attributes as defined in PI 1.8 Specification Cc: Felix Polyudov <[email protected]> Cc: Dhanaraj V <[email protected]> Cc: Liming Gao <[email protected]> Signed-off-by: Sachin Ganesh <[email protected]> Reviewed-by: Liming Gao <[email protected]>
Add the EFI_RESOURCE_ATTRIBUTE_SPECIAL_PURPOSE resource attribute as per the PI 1.8 spec. This flag is used to indicate that the memory should be treated as special purpose memory (SPM). Also adds GCD code that marks the SPM with the EFI_MEMORY_SP bit and sets the GCD memory type to EfiGcdMemoryTypeSystemMemory.
