| | | | | | | | | | | | | | | This patch fixes the following Ecc reported error: File header doesn't exist File header comment missing the ""Copyright"" Even though a copyright is present in the header file, the leading '*' char prevents the Ecc tool from detecting it. According to the edk2 coding specifcation, section 5.2.3 "File Heading", there should not be leading '*' char.

* ArmPlatformPkg/PL031RealTimeClockLib: cast EfiTimeToEpoch() val. to UINT32Laszlo Ersek2020-12-211-1/+1
| | | | | | | | | | | | | | | | | In preparation for changing EfiTimeToEpoch()'s return type to UINTN, cast EfiTimeToEpoch()'s retval to UINT32 explicitly, in LibSetTime(). Currently, this is a no-op, and even after widening the retval, it will make no difference, as LibSetTime() explicitly restricts Time->Year under 2106, given that "the PL031 is a 32-bit counter counting seconds". The patch is made for preventing compiler warnings.

* ArmPlatformPkg: list module-internal header files in INF [Sources]Laszlo Ersek2019-07-231-0/+1
| | | | | | | | | | | | | | | | | | The BaseTools build feature introduced for TianoCore#1804 / in commit 1fa6699e6cd4 ("BaseTools: Add a checking for Sources section in INF file", 2019-06-10) logs some (non-fatal) warnings about unlisted internal header files. List those files explicitly. Note: header files are added in lexicographical order only if the underlying INF file already keeps the [Sources] and [LibraryClasses] sections in lexicographical order. Otherwise, header files are added in rough "logical" order.

* ArmPlatformPkg: Actually disable PL031 interruptsAlexander Graf2019-07-101-2/+2
| | | | | | | | | | | | | | The PL031 interrupt mask register (IMSC) is not very clearly documented in the PL031 specification. However, bit 0 (RTCIMSC) indicates whether interrupts are enabled, not disabled. So before this commit, we were actually *enabling* interrupts for the RTC. This patch changes the logic to instead disable interrupts when they are not disabled already. Signed-off-by: Alexander Graf <graf@amazon.com> Reviewed-by: Leif Lindholm <leif.lindholm@linaro.org>

* ArmPlatformPkg/PL031RealTimeClockLib: depend on gEfiCpuArchProtocolGuidLaszlo Ersek2018-04-121-1/+4
| | | | | | | | | | | | | | | | | | | | | | The RealTimeClockLib class is declared under EmbeddedPkg, so that platforms can provide the internals for the EmbeddedPkg/RealTimeClockRuntimeDxe driver. In turn the driver produces the Real Time Clock Arch Protocol, without which UEFI drivers cannot be dispatched. The PL031RealTimeClockLib instance calls gDS->SetMemorySpaceAttributes() in the LibRtcInitialize() public function. This DXE service depends on the CPU Arch Protocol. Add it to the depex.

However, none of the remaining VExpress based hardware we support in EDK2 actuall implements this feature so we can just remove it, and get rid of the cumbersome dependency on ArmPlatform.h.

* ArmPlatformPkg/PL031RealTimeClockLib: ignore DST setting when timezone is setArd Biesheuvel2017-11-131-8/+4
| | | | | | | | | | | | | | | | | According to the UEFI spec, the timezone setting which the platform needs to record in addition to the actual date and time already reflects the current DST setting. In other words, moving the clock from standard time to daylight saving time also involves adding or subtracting 60 minutes from the timezone setting, as well as flicking the EFI_TIME_IN_DAYLIGHT bit in the DST setting. This means we need to disregard the DST setting if the timezone is specified, and only add or subtract the additional hour if we are on local time.

| | | | | | | | | | | | | | | PL031RealTimeClockLib is a base library that could potentially (although unlikely) be incorporated into other modules than the DXE_RUNTIME_DRIVER module that it was intended to complement. This means the library has no business whatsoever setting the Runtime Service table pointers directly (since we have no way of knowing which instance will 'win', and the pointers may end up referring to a module that is not a DXE_RUNTIME_DRIVER). So remove the assignment altogether.
