From 19c968222934835058e9ed3d515de744d8275213 Mon Sep 17 00:00:00 2001 From: "H. Nikolaus Schaller" Date: Fri, 28 Feb 2020 17:00:53 +0100 Subject: MIPS: DTS: CI20: make DM9000 Ethernet controller use NVMEM to find the default MAC address There is a unique MAC address programmed into the eFuses of the JZ4780 chip in the CI20 factory. By using this for initializing the DM9000 Ethernet controller, every CI20 board has an individual - but stable - MAC address and DHCP can assign stable IP addresses. Signed-off-by: H.
