One that would be based on real platform drivers and support both platform data and device tree. While we're far from reaching any consensus on the implementation, Arnd suggested that I start off by moving the SuperH-specific early platform drivers implementation to arch/sh[2]. This series is the first attempt at making way for a new, less hacky implementation. The first patch removes the last instance of a non-sh driver using the early_platform API. It can be removed since ARM no longer probes early drivers. The second patch moves all the early_platform code to arch/sh. The last patch prefixes all early_platform symbols with 'sh_'.
