There are many SH-2A CPUs with different feature sets, if you are looking for something in particular then you have appropriate channels for searching for parts that meet your requirements as well as people that can assist you with remedial problems. You have the same documentation to work with as the rest of us, so unless you're working on a prototype or unreleased CPU there's unlikely to be anything anyone can tell you that isn't documented in public specifications. Also keep in mind that we are talking about hundreds of different CPUs, while I can keep track of some of the differences on quite a number of them, I certainly couldn't tell you off the top of my head what CPU subtype has DMA auto-request modes for the LCDC block without looking at the same manuals you have. At the end of the day this is a technical forum. If you have general questions about given products or are looking for support outside of a technical kernel development level you have a number of venues open to you, including http://oss.renesas.com and whoever you locally source your components from.
