* Patch by Scott McNutt, 04 Oct 2003:
  - add support for Altera Nios-32 CPU
  - add support for Nios Cyclone Development Kit (DK-1C20)

* Patch by Steven Scholz, 29 Sep 2003:
  - A second parameter for bootm overwrites the load address for
    "Standalone Application" images.
  - bootm sets environment variable "filesize" to the resulting
    (uncompressed) data length for "Standalone Application" images
    when autostart is set to "no". Now you can do something like
       if bootm $fpgadata $some_free_ram ; then
               fpga load 0 $some_free_ram $filesize
       fi
