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_'. [1] https://lkml.org/lkml/2018/4/26/657 [2] https://lkml.org/lkml/2018/4/27/239 v1 -> v2: - certain drivers are compiled for arm/mach-shmobile too - we need to add ifdefs for CONFIG_SUPERH around early_platform calls v2 -> v3: - added a stub for is_early_platform_device() which always returns false on non-SuperH architectures RESEND: rebased on top of v4.18-rc1 and verified that there are no build failures. RESEND AGAIN: rebased on top of v4.19-rc1 and verified builds again.
