verified-boot: Minimal support for booting U-Boot proper from SPL
This allows a board to configure verified boot within the SPL using a FIT or FIT with external data. It also allows the SPL to perform signature verification without needing relocation. The board configuration will need to add the following feature defines: CONFIG_SPL_CRYPTO_SUPPORT CONFIG_SPL_HASH_SUPPORT CONFIG_SPL_SHA256 In this example, SHA256 is the only selected hashing algorithm. And the following booleans: CONFIG_SPL=y CONFIG_SPL_DM=y CONFIG_SPL_LOAD_FIT=y CONFIG_SPL_FIT=y CONFIG_SPL_OF_CONTROL=y CONFIG_SPL_OF_LIBFDT=y CONFIG_SPL_FIT_SIGNATURE=y Signed-off-by: Teddy Reed <teddy.reed@gmail.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Andreas Dannenberg <dannenberg@ti.com> Acked-by: Sumit Garg <sumit.garg@nxp.com>
