4 * This file is based on similar values for other boards found in other
5 * U-Boot config files, and some that I found in the mpc8260ads manual.
7 * Note: my board is a PILOT rev.
8 * Note: the mpc8260ads doesn't come with a proper Ethernet MAC address.
10 * (C) Copyright 2003 Arabella Software Ltd.
11 * Yuli Barcohen <yuli@arabellasw.com>
12 * Added support for SDRAM DIMMs SPD EEPROM, MII, JFFS2.
13 * Ported to PQ2FADS-ZU board.
