From 614a6a418eaad6869a6d19a5d441b0240861729f Mon Sep 17 00:00:00 2001 From: Max Krummenacher Date: Tue, 28 May 2019 13:52:34 +0200 Subject: imx-boot: use the right dcd for apalis-imx8a0 The Apalis iMX8 QM V1.0A require a specific DCD. Inject that DCD file and change the Makefile to actually use it.
