51c14cd128 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

ccf288612f rsa : Compile Modular Exponentiation files based on CONFIG_RSA_SOFTWARE_EXP
Remove dependency of rsa_mod_exp from CONFIG_FIT_SIGNATURE.
As rsa modular exponentiation is an independent module
and can be invoked independently.
