The best way to do all this platform specific configuration is to use
device tree. 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.

I tentatively agree, but this has to coexist with ACPI, which most of these platforms will also have,
for power management if nothing else.
