From c870e67a87ac4d8fe7ee2e4a458503058b397795 Mon Sep 17 00:00:00 2001 From: Huimin She Date: Tue, 8 Dec 2015 15:49:43 +0100 Subject: kernel: add device tree for t4240rdb MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A device tree (dts) is added for USDPAA support on t4240rdb. In the default USDPAA dts, all the ethernet interfaces are dedicated to USDPAA, so that they are not visible to Linux kernel. This brings difficulty for development, such as nfs booting and ssh login. In the new dts, one ethernet interface is reserved for Linux kernel network stack, and the others are for USDPAA.
