An EFI build of iPXE does not directly make use of a flattened device tree (FDT) itself, but may pass on a device tree that the user chose to download using the "fdt" command. Review the simple files used to implement the "fdt" command and mark these as permitted for UEFI Secure Boot. Signed-off-by: Michael Brown <mcb30@ipxe.org>
