For LinuxBIOS support: make linuxbios provide ACPI table include MADT,
SRAT, SLIT...but not DSDT.

and linux kernel will use ACPI table with DSDT and use MP Table to get
irq routing for devices.

You can not dump the DSDT in legacy BIOS and decode it and use it for
LinuxBIOS. that CP is belong to phoenix or AMI instead of MB vendor.
except dsdt for 8111/8131/8132 is from AMD.
