Subject: Patch by Jerry Van Baren, 08 Nov 2004: - Add low-boot option for
 MPC8260ADS board (if lowboot is selected,   the jumper for the HRCW source
 should select flash. If lowboot is   not selected, the jumper for the HRCW
 source should select the   BCSR. - change default load base address to
 0x00400000
