It is easy to note that SH2/SH3/SH4 start.S code is practically the same with a minor difference for SH2 where a short data header is present. To avoid unwanted code duplication and to automatically convert SH2 and SH3 platforms to generic board support move fixed SH4 start.S into arch/sh/lib/start.S and share it among all platforms.
