From d9f23c7fe20fced0a84713d5084a6d2896463257 Mon Sep 17 00:00:00 2001 From: Ruchika Gupta Date: Fri, 23 Jan 2015 16:01:56 +0530 Subject: [PATCH] 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 Acked-by: Simon Glass Signed-off-by: Simon Glass (Removed duplicate line in Kconfig comment) Change-Id: I7663c4d5350e2bfc3dfa2696f70ef777d6ccc6f6 --- lib/Kconfig | 7 +------ lib/rsa/Kconfig | 27 +++++++++++++++++++++++++++ 2 files changed, 28 insertions(+), 6 deletions(-) create mode 100644 lib/rsa/Kconfig diff --git a/lib/Kconfig b/lib/Kconfig index 79b91b7747..a1f30a2c4e 100644 --- a/lib/Kconfig +++ b/lib/Kconfig @@ -27,11 +27,6 @@ config SYS_HZ get_timer() must operate in milliseconds and this option must be set to 1000. -config RSA - bool "Use RSA Library" - help - RSA support.
