* DynamicTablesPkg: add validation for PcdNonBsaCompliant16550SerialHidJoey Gouly2021-04-131-1/+37
| | | | | | | | | | | | According to ACPI 6.4, 6.1.5 _HID states: - A valid PNP ID must be of the form "AAA####" where A is an uppercase letter and # is a hex digit. - A valid ACPI ID must be of the form "NNNN####" where N is an uppercase letter or a digit ('0'-'9') and # is a hex digit.

* DynamicTablesPkg: SSDT Serial Port Fixup libraryPierre Gondois2020-08-131-0/+68
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* DynamicTablesPkg: AmlLib APIsPierre Gondois2020-08-131-0/+631
| | | | | | | | | | | | | | | | AmlLib library implements an AML parser, AML tree interface, serialiser, code generator and other interfaces to generate Definition Block tables. The AmlLib APIs are a collection of interfaces that enable parsing, iterating, modifying, adding, and serialising AML data to generate a Definition Block table. The AmlLib APIs are declared in Include\AmlLib\AmlLib.h Signed-off-by: Pierre Gondois <pierre.gondois@arm.com> Signed-off-by: Sami Mujawar <sami.mujawar@arm.com> Reviewed-by: Alexei Fedorov <Alexei.Fedorov@arm.com>
* DynamicTablesPkg: Add code for finding duplicate values in arraysKrzysztof Koch2019-06-101-0/+48
| | | | | | | | | | | | Added generic function for detecting duplicate values in an array. Also defined a function prototype to test if two objects are equal. The prototype is used as an argument to the 'FindDuplicateValues' function.
