* 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
