Public exponentiation which is required in rsa verify functionality is tightly integrated with verification code in rsa_verify.c. The patch splits the file into twp separating the modular exponentiation.
- rsa-verify.c
- The file parses device tree keys node to fill a keyprop structure.
The keyprop structure can then be converted to implementation specific format. (struct rsa_pub_key for sw implementation)
- The parsed device tree node is then passed to a generic rsa_mod_exp
function.
- rsa-mod-exp.c
Move the software specific functions related to modular exponentiation from rsa-verify.c to this file.

Changes in v6: No changes
Changes in v5: Reverted change in rsa_mod_exp_sw function to add pointer to output length Addressed other comments by Simon
Changes in v4: Modified rsa_mod_exp_sw function to add pointer to output length
Changes in v3: Kconfig moved to separate patch. This patch just splits the file now
Changes in v2: Addressed few of Simon Glass's comments:
- Kconfig option added for RSA
- Comments added for new keyprop struct

Applied to u-boot-dm, thanks!
