[U-Boot] [PATCH 7/9] [v4] 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 Signed-off-by: Ruchika Gupta CC: Simon Glass --- Changes in v4: Introduced 2 options when CONFIG_RSA is selected: RSA_SOFTWARE_EXP RSA_FREESCALE_EXP Removed RSA_HW.
