From 36d7418afa42fbb2dccc435860f3d95721fb9652 Mon Sep 17 00:00:00 2001 From: Paul Kocialkowski Date: Fri, 22 Apr 2016 11:10:03 +0200 Subject: chromeos: Ensure that the last file in FW_MAIN is not also the first one In the case where one of the FW_MAIN regions is empty, the last file (empty) will also appear to be first and have a zero offset, making head complain. This is a very borderline use case, since the FW_MAIN_ regions should have been filled previously, but an extra check doesn't hurt.
