From 6bedf44714a145e09fddb8c5a03ada210b812ec9 Mon Sep 17 00:00:00 2001 From: Prabhakar Kushwaha Date: Thu, 23 Nov 2017 16:51:41 +0530 Subject: arm: Add support of updating dts before fix-up "ethernet" node fix-up for device tree happens before Linux boot. There can be requirement of updating "ethernet" node even before fix-up. So, add support of updating "ethernet" node.
