Revert "ArmPlatformPkg,EmbeddedPkg,MdeModulePkg: Move RealTimeClockLib ..."

2026-05-06T03:41:31+00:00

This reverts commit 57230fff6b39a665485be1bd43ec608d412ba6fb. RealTimeClockLib is not a generic library class that is intended to be used widely to get access to the RTC when the associated runtime services are not available in the calling context. The purpose of RealTimeClockLib is to abstract the underlying hardware access from the generic RealTimeClockRuntimeDxe driver, which backs the runtime services. This means it does not belong in a different package; it belongs in the same package as the driver. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Ard Biesheuvel

ArmPlatformPkg: Replace include guards with #pragma once

2026-02-23T21:01:28+00:00

Replace traditional `#ifndef`/`#define`/`#endif` include guards with `#pragma` once. `#pragma once` is a widely supported preprocessor directive that prevents header files from being included multiple times. It is supported by all toolchains used to build edk2: GCC, Clang/LLVM, and MSVC. Compared to macro-based include guards, `#pragma once`: - Eliminates the risk of macro name collisions or copy/paste errors where two headers inadvertently use the same guard macro. - Eliminate inconsistency in the way include guard macros are named (e.g., some files use `__FILE_H__`, others use `FILE_H_`, etc.). - Reduces boilerplate (three lines replaced by one). - Avoids polluting the macro namespace with guard symbols. - Can improve build times as the preprocessor can skip re-opening the file entirely, rather than re-reading it to find the matching `#endif` ("multiple-include optimization"). - Note that some compilers may already optimize traditional include guards, by recognzining the idiomatic pattern. This change is made acknowledging that overall portability of the code will technically be reduced, as `#pragma once` is not part of the C/C++ standards. However, this is considered acceptable given: 1. edk2 already defines a subset of supported compilers in BaseTools/Conf/tools_def.template, all of which have supported `#pragma once` for over two decades. 2. There have been concerns raised to the project about inconsistent include guard naming and potential macro collisions. Approximate compiler support dates: - MSVC: Supported since Visual C++ 4.2 (1996) - GCC: Supported since 3.4 (2004) (http://gnu.ist.utl.pt/software/gcc/gcc-3.4/changes.html) - Clang (LLVM based): Since initial release in 2007 Signed-off-by: Michael Kubacki

ArmPlatformPkg/PL011UartLib : Fix incorrect control bit validation

2026-02-13T11:36:36+00:00

REF: [e092122] (PR #12085) The current logic in ArmPlatformPkg/PL011UartLib performs control-bit checks intended to align with the UEFI specification. However, it incorrectly validates control bits that cannot be set through SetControl(), resulting in failures in the SetControl() SCT test. According to the UEFI specification, the valid control bits that can be set are: EFI_SERIAL_REQUEST_TO_SEND EFI_SERIAL_DATA_TERMINAL_READY EFI_SERIAL_HARDWARE_LOOPBACK_ENABLE EFI_SERIAL_SOFTWARE_LOOPBACK_ENABLE EFI_SERIAL_HARDWARE_FLOW_CONTROL_ENABLE This patch updates mAllowedControlBits so that only these valid control bits are accepted during validation.

ArmPlatformPkg/PL011UartLib : Fix SetControl() SCT conformance

2026-02-06T01:27:48+00:00

REF: pftf/RPi4#87 The PL011UartLib SetControl() is failing the SCT test for SerialIoBBTestConformance (00605CBC-3965-4B61-A254-2B2B723172EA), which is trying to set bits that are not supported per UEFI spec. Add proper argument check for valid bits, and confirm that test passes. Cc: Leif Lindholm Cc: Ard Biesheuvel Cc: Sami Mujawar Signed-off-by: Samer El-Haj-Mahmoud

ArmPlatformPkg: rename LcdHwLibNull and LcdPlatformLibNull

ArmPlatformPkg,EmbeddedPkg,MdeModulePkg: Move RealTimeClockLib header

2025-09-08T08:54:42+00:00

RealTimeClockLib is an architectural implementation that is not restricted to the embedded segment or any platform in particular. So the header has been moved to MdeModulePkg. And the package has been added to the relevant INF files. Continuous-integration-options: PatchCheck.ignore-multi-package Signed-off-by: Sachin Ganesh
