From 2090f1e3d096bd124790e1716240e17e56325755 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 24 Aug 2019 07:23:00 -0600 Subject: [PATCH] binman: Allow symbols to be resolved inside sections At present we only support symbols inside binaries which are at the top level of an image. This restrictions seems unreasonable since more complex images may want to group binaries within different sections. Relax the restriction, adding a new _SetupTplElf() helper function. Also fix a typo in the comment for testTpl().
