From c4beb22fcd8cf57569a8045c8e04cea0dbbfd763 Mon Sep 17 00:00:00 2001 From: Ruchika Gupta Date: Fri, 23 Jan 2015 16:01:51 +0530 Subject: [PATCH] FIT: Modify option FIT_SIGNATURE in Kconfig For FIT signature based approach to work, RSA library needs to be selected. The FIT_SIGNATURE option in Kconfig is modified to automatically select RSA. Selecting RSA compiles the RSA library required for image verification.
