* 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
* Patch by Denis Peter, 25 Sept 2003:
add support for the MIP405 Rev. C board
