[PATCH 0/3] sh: make early_platform code SuperH-specific

[Bartosz Golaszewski]

I recently 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 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_'.
