2.3. Locations of Source and Patches

Each tool in the tool chain is built from its source code. In all cases the source code is derived from the standard source code by patching with changes required for OpenRISC 1000. So for each tool there will be one source distribution to download (typically as a compressed tar file) and one or more patch files (typically compressed).

Locations of the patch files for each tool are noted here. Where more than one location is given for the same item, they represent alternative download points for the same file.

	Note
	Some of these are FTP sites and some HTTP site. All should be accessible through a web browser using the link shown. Downloads from the OpenCores website requires a login (which is free). Some other downloads may require login and password, which are given in the table.
