efi_loader: Add device path related functions for initrd via Boot####
On the following patches we allow for an initrd path to be stored in Boot#### variables. Specifically we encode in the FIlePathList[] of the EFI_LOAD_OPTIONS for each Boot#### variable. The FilePathList[] array looks like this: kernel - 0xff - VenMedia(initrd GUID) - initrd1 - 0x01 initrd2 - 0xff So let's add the relevant functions to concatenate and retrieve a device path based on a Vendor GUID. Signed-off-by: Ilias Apalodimas <ilias.apalodimas@linaro.org> Reformat function descriptions. Reviewed-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
