From 1152a05ee6593bf3036337cd18edd355589ea3a8 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 3 Jul 2016 09:40:44 -0600 Subject: [PATCH] tools: Correct error handling in fit_image_process_hash() We should not be returning -1 as an error code. This can mask a situation where we run out of space adding things to the FIT. By returning the correct error in this case (-ENOSPC) it can be handled by the higher-level code. This may fix the error reported by Tom Van Deun here: https://www.mail-archive.com/u-boot@lists.denx.de/msg217417.html although I am not sure as I cannot actually repeat it.
