From ff5d7ae713ac6de37f3a93f3a4fed13ab4ffd154 Mon Sep 17 00:00:00 2001 From: Fabian Vogt Date: Mon, 26 Sep 2016 14:26:48 +0200 Subject: [PATCH] fdt: adjust bcm283x device tree for u-boot The information currently set via platdata has to be represented in the device tree now. bcm283x-uboot.dtsi adds the u-boot specific "skip-init" property to the serial nodes and enables initialization in the pre-reloc phase.
