From: Niklaus Giger Date: Fri, 30 Nov 2007 15:01:58 +0100 Subject: [U-Boot-Users] [PATCH] PPC4xx: Minimal changes to add vxWorks support Message-ID: <200711301501.58665.niklausgiger@gmx.ch> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de Hi I have to support vxWorks on our boards. In order to avoid changing the TLB in all PPC440x based boards I need this small patch. Can it go into the git repository or do I have to maintain it out of the tree forever?
