OK, I don't get any feedbacks since my original post but I had time to make some changes... It's now based on "linux-2.6.22-rc4-357-g7518784", with a part of Ralf's linux-time patches. I'd like to port some 'interesting' platforms as a proof of concept. Could anybody name them ? I'd like to port a platform that uses the 'hpt' as clock source and timer. A second one that uses the hpt only as a timer, and a third one that doesn't uses it at all. A small description can help too...
