arm: mvebu: Implement secure boot
The patch implements secure booting for the mvebu architecture. This includes: - The addition of secure headers and all needed signatures and keys in mkimage - Commands capable of writing the board's efuses to both write the needed cryptographic data and enable the secure booting mechanism - The creation of convenience text files containing the necessary commands to write the efuses The KAK and CSK keys are expected to reside in the files kwb_kak.key and kwb_csk.key (OpenSSL 2048 bit private keys) in the top-level directory.
