The UEFI spec allows a packed array of UEFI device paths in the FilePathList[] of an EFI_LOAD_OPTION. The first file path must describe the loaded image but the rest are OS specific. Previous patches parse the device path and try to use the second member of the array as an initrd. So let's modify efidebug slightly and install the second file described in the command line as the initrd device path. Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org>
