* Patch by Nicolas Lacressonniere, 11 Jun 2003:
Modifications for Atmel AT91RM9200DK ARM920T based development kit - Add Atmel DataFlash support for reading and writing. - Add possibility to boot a Linux from DataFlash with BOOTM command. - Add Flash detection on Atmel AT91RM9200DK (between Atmel AT49BV1614 and AT49BV1614A flashes) - Replace old Ethernet PHY layer functions - Change link address * Patch by Frank Smith, 9 Jun 2003: use CRIT_EXCEPTION for machine check on 4xx * Patch by Detlev Zundel, 13 Jun 2003: added implementation of the "carinfo" command in cmd_immap.c
