Great progress If you are looking for ASL support there is some BSD-licensed code at https://svn.code.sf.net/p/edk2/code/trunk/edk2/Vlv2DeviceRefCodePkg/AcpiTablesPCAT for example. ASL should be reasonable portable across various boot loader infrastructure codebase technologies - edkII, coreboot, uboot,.... Vincent
