From 7e64abdb8d5d6b551a6f7cfb87e73cc0187099fb Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Thu, 2 Jun 2016 19:59:54 -0300 Subject: [PATCH] configs: new configuration for NXP i.MX51 EVK Add a new configuration for NXP i.MX51 EVK based on U-boot 2016.05 and kernel 4.6.1. U-boot 2016.05 needs the patch c510f2e436008 ("video: ipu_common: fix build error") that is already in mainline to fix an IPU build error. We can remove this patch in the future when we switch to U-boot 2016.07.
