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 ruchika.gupta@freescale.com CC: Simon Glass sjg@chromium.org --- Changes in v4: Introduced 2 options when CONFIG_RSA is selected: RSA_SOFTWARE_EXP RSA_FREESCALE_EXP
Removed RSA_HW. Changes the name pf RSA_SW to RSA_SOFTWARE_EXP
Changes in v3: New patch
