Linux x86 kernel has various sources for it to configure the hardware,
via configuration tables like PIRQ/SFI/MP/ACPI and device tree. You
can describe all configuration in the device tree without using other
mechanism. There is no such limitation as long as you come up with a
proper binding for Linux kernel to use.
