From d9f23c7fe20fced0a84713d5084a6d2896463257 Mon Sep 17 00:00:00 2001 From: Ruchika Gupta Date: Fri, 23 Jan 2015 16:01:56 +0530 Subject: 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/rsa/Kconfig | 27 +++++++++++++++++++++++++++ 1 file changed, 27 insertions(+) create mode 100644 lib/rsa/Kconfig (limited to 'lib/rsa') diff --git a/lib/rsa/Kconfig b/lib/rsa/Kconfig new file mode 100644 index 0000000000..1268a1b2db --- /dev/null +++ b/lib/rsa/Kconfig @@ -0,0 +1,27 @@ +config RSA + bool "Use RSA Library" + select RSA_FREESCALE_EXP if FSL_CAAM + select RSA_SOFTWARE_EXP if !RSA_FREESCALE_EXP + help + RSA support.
