From 4a5517094dd30bb1f271403b62e23053301668e6 Mon Sep 17 00:00:00 2001 From: wdenk Date: Wed, 8 Oct 2003 23:26:14 +0000 Subject: * 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.
