When booting Linux with EFI the devicetree memory-map is ignored and Linux calls through EFI to obtain the real memory map. When booting Linux from the EFI app, without EFI, we must pass the reserved memory onto Linux using the devicetree. Add a function to support this. It reads the EFI memory-map and adds any missing regions to the reserved-memory node. Co-developed-by: Claude <noreply@anthropic.com> Signed-off-by: Simon Glass <sjg@chromium.org>
