RSA_SOFTWARE_EXP and RSA_FREESCALE_EXP are wrapped inside:
if RSA
...
endif
So, remove the redundant "depends on RSA" from their depends expression.
In addition, move SPL_RSA into the same "if RSA ... endif" block, since
its only direct dependeny is CONFIG_RSA. This tidies up and simplifies
reading of lib/rsa/Kconfig.
No functional change intended.

The CAAM in IMX parts doesn't support public key hardware acceleration
(PKHA), so don't use RSA_FREESCALE_EXP. If you try to use it on IMX
(assuming you have the clocks enabled first) you will get back an
"Invalid KEY Command" error since PKHA isn't a valid key destination for
these parts.

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

There are already two FIT options in Kconfig but the CONFIG options are
still in the header files. We need to do a proper move to fix this.
Move these options to Kconfig and tidy up board configuration:
CONFIG_FIT
CONFIG_OF_BOARD_SETUP
CONFIG_OF_SYSTEM_SETUP
CONFIG_FIT_SIGNATURE
CONFIG_FIT_BEST_MATCH
CONFIG_FIT_VERBOSE
CONFIG_OF_STDOUT_VIA_ALIAS
CONFIG_RSA
Unfortunately the first one is a little complicated. We need to make sure
this option is not enabled in SPL by this change. Also this option is
enabled automatically in the host builds by defining CONFIG_FIT in the
image.h file. To solve this, add a new IMAGE_USE_FIT #define which can
be used in files that are built on the host but must also build for U-Boot
and SPL.
Note: Masahiro's moveconfig.py script is amazing.

Kconfig option added for devices which support RSA Verification.
1. RSA_SOFTWARE_EXP
Enables driver for supporting RSA Modular Exponentiation in Software
2. RSA_FREESCALE_EXP
Enables driver for supporting RSA Modular Exponentiation using Freescale specific
driver
The above drivers use RSA uclass
