From 124ec188720b6bdea85ade49e7ea195161b12fce Mon Sep 17 00:00:00 2001 From: Mike Frysinger Date: Sat, 5 Jan 2008 10:05:27 +0000 Subject: Chris Zankel writes: The following patches add support for the Xtensa processor architecture to uClibc. They are based on a recent SVN checkout (12/05/2007). The first patch (attached to this post) adds Xtensa support to various shared configuration and make files. The following patches then include the Xtensa specific files and directories. I welcome any feedback and would appreciate it if you could include the patches into the mainline tree. I am certainly committed to maintain the port. Bob Wilson was kind enough to review the patches. Some notes about the architecture: Xtensa is a configurable and extensible processor architecture developed by Tensilica.
