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> Acked-by: Simon Glass <sjg@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org> (Removed duplicate line in Kconfig comment) Change-Id: I7663c4d5350e2bfc3dfa2696f70ef777d6ccc6f6
