Subject: [U-Boot-Users] [PATCH] PPC4xx: Minimal changes to add vxWorks support
Date: Fri, 30 Nov 2007 15:01:58 +0100	[thread overview]
Message-ID: <200711301501.58665.niklausgiger@gmx.ch> (raw)

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?

Best regards
