From mboxrd@z Thu Jan 1 00:00:00 1970 From: Chris Zankel Date: Wed, 07 Nov 2012 19:38:45 -0800 Subject: [Buildroot] [PATCH 1/2] xtensa: add support for the Xtensa architecture Message-ID: <509b2947.a6e6440a.547c.7082@mx.google.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net The original support for the Xtensa architecture in buildroot required a lot of special handling and additional files, so it became hard to maintain. This implementation is much more aligned to other architectures with only minimal overhead.
