   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.

  12  * Added support for SDRAM DIMMs SPD EEPROM, MII, JFFS2.
  13  * Ported to PQ2FADS-ZU and PQ2FADS-VR boards.
