wdenk 6069ff2653 * Add support for 16 MB flash configuration of TRAB board
* Patch by Erwin Rol, 27 Feb 2003:
  Add support for RTEMS

* Add image information to README

* Fix dual PCMCIA slot support (when running with just one
  slot populated)

* Add VFD type detection to trab board

* extend drivers/cs8900.c driver to synchronize  ethaddr  environment
  variable with value in the EEPROM

* Start adding MIPS support files
