No need for Mr. Everywhere to know about the SoC. There are other ways to achieve this. arch/arm/mach-foo always knows which ASIC it is running on, and it can do various things: - Add device tree fragments/overlays (OK high-tech, but we're getting to this, inevitably) - Selectively add AUXDATA, which is absolutely OK if we can do autoprobing of hardware IMO.
