From d7be50921ed35e36e000a5e8daba41701a5eebb9 Mon Sep 17 00:00:00 2001 From: "Andrew F. Davis" Date: Tue, 29 Nov 2016 16:33:20 -0600 Subject: image: Add FIT image loadable section custom processing To help automate the loading of custom image types we add the ability to define custom handlers for the loadable section types. When we find a compatible type while loading a "loadable" image from a FIT image we run its associated handlers to perform any additional steps needed for loading this image. Signed-off-by: Andrew F.
