From 9ebb123893db56ef402a742aca0eeda4224da987 Mon Sep 17 00:00:00 2001

Subject: [PATCH] board/boundarydevices: update u-boot scripts for 3.14 kernels

Those scripts will support coming platforms such as iMX6SoloX or
iMX6QuadPlus.

One important change is that the bootscript now relies on U-Boot to
make the display detection in order to simplify the script.
