The existing options, "--fit" and "--raw," are only used to put a proper GUID in a capsule header, where GUID identifies a particular FMP (Firmware Management Protocol) driver which then would handle the firmware binary in a capsule. In fact, mkeficapsule does the exact same job in creating a capsule file whatever the firmware binary type is.
To prepare for the future extension, the command syntax will be a bit modified to allow users to specify arbitrary GUID for their own FMP driver. OLD: [--fit <image> | --raw <image>] <capsule file> NEW: [--fit | --raw | --guid <guid-string>] <image> <capsule file>
