Loads a PEIM into memory for subsequent execution.
This service is the single member function of EFI_LOAD_FILE_PPI.
This service separates image loading and relocating from the PEI Foundation.
@param This Interface pointer that implements
the Load File PPI instance.
@param FileHandle File handle of the file to load.
@param ImageAddress Pointer to the address of the loaded image.
@param ImageSize Pointer to the size of the loaded image.
@param EntryPoint Pointer to the entry point of the image.
@param AuthenticationState On exit, points to the attestation
authentication state of the image
or 0 if no attestation was performed.
@retval EFI_SUCCESS The image was loaded successfully.
@retval EFI_OUT_OF_RESOURCES There was not enough memory.
@retval EFI_LOAD_ERROR There was no supported image in the file.
@retval EFI_INVALID_PARAMETER FileHandle was not a valid firmware file handle.
@retval EFI_INVALID_PARAMETER EntryPoint was NULL.
@retval EFI_UNSUPPORTED An image requires relocations or is not
memory mapped.
@retval EFI_WARN_BUFFER_TOO_SMALL
There is not enough heap to allocate the requested size.
This will not prevent the XIP image from being invoked.
