From 228c37ff980f5643401a1667f5ab7c6f38602cf8 Mon Sep 17 00:00:00 2001 From: David Howells Date: Tue, 11 Aug 2015 12:38:54 +0100 Subject: [PATCH] sign-file: Document dependency on OpenSSL devel libraries The revised sign-file program is no longer a script that wraps the openssl program, but now rather a program that makes use of OpenSSL's crypto library. This means that to build the sign-file program, the kernel build process now has a dependency on the OpenSSL development packages in addition to OpenSSL itself. Document this in Kconfig and in module-signing.txt.
