I really don't want to have x86/mach-xyz/board[A-Z] horror, which is unavoidable when we don't get a sensible way to configure the boards. SFI was meant to provide a lightweight ACPI, but now that device tree is generic and more platforms are using it, I really want to standartize on that and forget SFI. That makes even more sense, as all these AMBA peripherals which are duct-taped to a x86 core can be found in other SoCs with different cores as well.
