From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx> Some time ago I started a discussion about the need for a proper early device probing mechanism[1]. 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 moves all the early_platform code to arch/sh. The second patch prefixes all early_platform symbols with 'sh_'.
