Pierre Gondois 5a5440d0dc ArmPlatformPkg: Fix Ecc error 8001
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.

Laszlo Ersek 3af6c521d9 ArmPlatformPkg/PL031RealTimeClockLib: cast EfiTimeToEpoch() val. to UINT32
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.

Laszlo Ersek 2a0168c7c0 ArmPlatformPkg: list module-internal header files in INF [Sources]
The BaseTools build feature introduced for TianoCore#1804 / in commit
1fa6699e6c ("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.

Alexander Graf 8df52631e5 ArmPlatformPkg: Actually disable PL031 interrupts
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.

The comments describes the device as being 32-bit:
"the maximum time span is just over 136 years"
then uses a UINTN to hold the value.

Laszlo Ersek 221c4f626f ArmPlatformPkg/PL031RealTimeClockLib: depend on gEfiCpuArchProtocolGuid
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.

battery backed clock in addition to the PL031. 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.

Ard Biesheuvel 207bc6a38c ArmPlatformPkg/PL031RealTimeClockLib: ignore DST setting when timezone is set
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.

Ard Biesheuvel 3ad72779aa ArmPlatformPkg/PL031RealTimeClockLib: don't clobber gRT table
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.
