* 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
