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. For more
information, please visit: www.linux-xtensa.org.
