DynamicTablesPkg: Dynamic AML: Add AmlLib library ACPI Definition blocks are implemented using AML which has a complex grammar making run-time generation of definition blocks difficult. Dynamic AML is a feature of Dynamic Tables framework that provides a solution for dynamic generation of ACPI Definition block tables. Since, AML bytecode represents complex AML grammar, an AmlLib library is introduced to assist parsing and traversing of the AML bytecode at run-time. The AmlLib library parses a definition block and represents it as an AML tree. The AML objects, methods and data are represented as tree nodes. Since the AML data is represented as tree nodes, it is possible to traverse the tree, locate a node and modify the node data. The tree can then be serialized to a buffer (that represents the definition block). This definition block containing the fixed-up AML code can then be installed as an ACPI Definition Block table. Dynamic AML introduces the following techniques: * AML Fixup * AML Codegen * AML Fixup + Codegen AML Fixup is a technique that involves compiling an ASL template file to generate AML bytecode. This template AML bytecode can be parsed at run-time and a fixup code can update the required fields in the AML template. AML Codegen employs generating small segments of AML code. AmlLib provides a rich set of APIs to operate on AML data for AML Fixup and Codegen.

DynamicTablesPkg: SSDT Serial Port Fixup library According to Arm Server Base Boot Requirements, Platform Design Document version 1.2 revision D, September 2, 2019, section '4.2.1.8 SPCR'; The SPCR console device must be included in the DSDT. Additionally, it is often desirable to describe the serial ports available on a platform so that they are available for use by a rich OS. To facilitate the description of serial ports on a platform a common SSDT Serial Port Fixup library is introduced. It provides interfaces to build a SSDT serial port definition block table based on the serial port information. The SSDT Serial Port Fixup library is used by the SPCR, DBG2 and SSDT Serial Port generator to describe the serial port information in a definition block. +------------+ +------------+ +------------+ | SPCR Gen | | DBG2 Gen | | SERIAL Gen | +------------+ +------------+ +------------+ +----------------------------------+ | SSDT Serial Port Fixup library | +----------------------------------+ The SSDT Serial Port Fixup library: - Parses the SSDT Serial Port template using the AmlLib library to generate an AML tree. - Updates the _UID, _HID and _CID values. - Fixes up the Serial port base address, length and the interrupt number in the _CRS descriptor. - Fixes up the serial-port name. - Serialises the AML Tree to a buffer containing the definition block data. The definition block data is then installed by the corresponding table generator.
