We are trying to build ACPI for PPC e300 core . The problem is we donot have a BIOS running to supply the System Descriptor Tables to ACPI during boot. So ACPI gets disabled during boot. Are the system desc tables must for the ACPI to run? Or is there a method where we can avoid these tables and make ACPI work directly. Without BIOS how do we make ACPI up and running?
