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
