Ruchika Gupta d9f23c7fe2 lib/rsa: Add Kconfig for devices supporting RSA Modular Exponentiation
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

RSA support. This enables the RSA algorithm used for FIT image
verification in U-Boot.
See doc/uImage.FIT/signature.txt for more details.

Enables driver for modular exponentiation in software. This is a RSA
algorithm used in FIT image verification. It required RSA Key as
input.
See doc/uImage.FIT/signature.txt for more details.

depends on DM && RSA && FSL_CAAM
help
Enables driver for RSA modular exponentiation using Freescale cryptographic
accelerator - CAAM.
