From b5e7586a73d4eb7b0aa9c597f293a584a2a1800a Mon Sep 17 00:00:00 2001 From: Michael Heimpold Date: Tue, 1 Sep 2015 23:58:44 +0200 Subject: [PATCH] mxs: mxsboot: fix endianess for sd boot images Running mxsboot on a big-endian system produces a sd image which cannot be started by the i.MX28 ROM. It complains on the debug uart as following: 0x8020a009 0x80502008 0x8020a009 0x80502008 ... Enforcing all fields within the BCB to little-endian make the image bootable again.
