From 34fc4ab80b507739e2580d490dff67fcfdde11ea Mon Sep 17 00:00:00 2001 From: "Ronald G. Minnich" Date: Mon, 6 Oct 2014 15:30:37 +0000 Subject: mkelfimage: remove It's not been needed for years, is definitely not needed now that cbfstool parses bzImages, and its presence keeps confusing people. Also, rewrite history. We never mentioned mkelfimage in the documentation. Never, ever, ever. Change-Id: Id96a57906ba6a423b06a8f4140d2efde6f280d55 Signed-off-by: Ronald G.
