From e003310a76211c2a9bb1939db4633830594c35ba Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Mon, 22 May 2017 05:05:33 -0600 Subject: bootstage: Tidy up error return values We should return a proper error number instead of just -1. This helps the caller to determine what when wrong. Update a few functions to fix this.
