From f535daed925c2d3c1db06b06a63c4955f2c51988 Mon Sep 17 00:00:00 2001 From: Kan-Ru Chen Date: Mon, 2 Aug 2010 14:21:41 +0300 Subject: [PATCH] omap: Devkit8000: Use DIE id to initialize dm9000 MAC address The devkit8000 boards often come with empty EEPROM thus without valid ethernet MAC address. The DIE id to MAC formula is copied from u-boot.
