From e324a92531e1dc092949b8a00745afd2328e178e Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 30 Jun 2016 10:52:09 -0600 Subject: [PATCH] mkimage: Require a data file when auto-fit is used When auto-fit is used, it is not valid to create a FIT without an image file. Add a check for this to avoid a very confusing error message later ("Can't open (null): Bad address").
