Ard Biesheuvel 7c138e4008 EmbeddedPkg/PrePiLib: Drop unused PCD PcdPrePiCpuIoSize
The code never references the PCD so the INF should not reference it
either. The last reference was moved to PrePiHobLib in commit
05e48e0083 (dated 2011!) and dropped from there as well in
commit 9710639195.

Min M Xu 0826808d4f EmbeddedPkg: Rename FfsFindSectionData as FfsFindSectionDataWithHook
Commit c673216f53 introduces FFS_CHECK_SECTION_HOOK and add it as the
second input parameter in FfsFindSectionData. This change breaks the build
of ArmVirtPkg. To fix this issue, the new version of FfsFindSectionData
is renamed as FfsFindSectionDataWithHook in this patch. In the following
patch the original FfsFindSectionData will be added back.

FfsFindSectionData is renamed as FfsFindSectionDataWithHook. Accordingly
PeilessStartupLib in OvmfPkg should be updated as well. To prevent the
build from being broken, the changes in OvmfPkg are in this patch.

with the same SectionType. FFS_CHECK_SECTION_HOOK is a hook which can
be called to do additional check.

Sunny Wang 8e6bb64fe4 EmbeddedPkg/VirtualRealTimeClockLib: Fix SetTime issues
This patch fixes two issues below:
1. SCT SetTime_Func failures.
   - https://github.com/pftf/RPi4/issues/164
2. Using shell time and date commands to set time can't work.

The problem is that gRT->SetTime always returns EFI_INVALID_PARAMETER
error status.

The root cause is that LibSetTime() sets RtcEpochSeconds variable with
inconsistent attributes. One is without EFI_VARIABLE_NON_VOLATILE,
the other one is with EFI_VARIABLE_NON_VOLATILE. That caused that the
variable driver returns EFI_INVALID_PARAMETER. Per UEFI spec, if a
preexisting variable is rewritten with different attributes,
SetVariable() shall not modify the variable and shall return
EFI_INVALID_PARAMETER.

Therefore, the solution is to add EFI_VARIABLE_NON_VOLATILE attribute
to the first EfiSetVariable() call to make two calls consistent.

By the way, this patch also fix a minor issue with a debug message.

Rebecca Cran 94fa95c874 EmbeddedPkg: Only print LibGetTime message about compile time epoch once
The message "LibGetTime: RtcEpochSeconds non volatile variable was not
found - Using compilation time epoch." can be printed a very large
number of times, causing log files to become excessively large. This is
because the RtcEpochSeconds variable only gets set if LibSetTime is
called, for example by running 'time 12:00' in the UEFI Shell.

Avoid this by setting RtcEpochSeconds to BUILD_EPOCH (EpochSeconds)
after printing the message. It's set to a volatile variable so the
message will be displayed on future boots and not hidden.

Commit 44ae214591 reduced the verbosity of
the message to DEBUG_VERBOSE. Revert it back to DEBUG_INFO so it's more
prominent now that it doesn't get printed so frequently.

Pete Batard 24cf727265 EmbeddedPkg/VirtualRealTimeClockLib: Explicit cast to UINT32
Addresses BZ https://bugzilla.tianocore.org/show_bug.cgi?id=2380 where
explicit casts are required for 64 to 32 bit assignment.

We can apply a straight cast for Time->Nanosecond since we already checked
for overflow.

On the other hand, we may have a frequency that is greater than UINT32_MAX
for Capabilities->Resolution. But using the frequency for the resolution
is the wrong approach anyway, since we can't actually vouch for the actual
resolution of the virtual library. Instead, play it safe by defaulting to
1 Hz, which is what a standard PC-AT CMOS RTC device would use.

the Image was loaded and an ImageHandle was created with a valid
EFI_LOADED_IMAGE_PROTOCOL, but the image can not be started right now.
This follows UEFI Spec.

But if the caller of LoadImage() doesn't have the option to defer

like any other LoadImage() error, we should unload image for the
EFI_SECURITY_VIOLATION to avoid resource leak.

This patch is to do error handling for EFI_SECURITY_VIOLATION explicitly

Marcin Wojtas 20029ca22b EmbeddedPkg: Allow DXE_DRIVER to depend on NvVarStoreFormattedLib
Some modules (such as FaultTolerantWriteDxe) use the FlashNvStorage
PCDs (PcdFlashNvStorageFtw*). In case the flash contents are not
mapped in memory, the module loading order of the FVB driver
may become important.

To handle above, this patch allows to hook the dependency of
desired DXE_DRIVER type module in the .DSC file via
NvVarStoreFormattedLib NULL resolution.

Pete Batard 1342d7679e EmbeddedPkg/VirtualRealTimeClockLib: Fix correctness issues
LibGetTime():
- Two variables were used for the epoch, where only one should have been [*].
- Also harmonize variable name to match the one used in LibSetTime.
LibSetTime():
- Address possible underflows if time is set to start of epoch.
- Ensure that time being read does actually match time that was manually
  set (plus the time elapsed since), by subtracting number of seconds
  since reset.

[*] This fixes a build breakage, since one of these variables was set but
    never used, triggering a compiler diagnostic at some optimization levels.

Pete Batard 64a17fadcb EmbeddedPkg/Library: Add VirtualRealTimeClockLib
This is designed to be used on platforms where a a real RTC is not
available and relies on an RtcEpochSeconds variable having been set or,
if that is not the case, falls back to using the epoch embedded at
compilation time.

Note that, in order to keep things simple for the setting of the
compilation time variable, only GCC environments with UNIX-like shells
and where a 'date' command is available are meant to be supported for
now.

Ard Biesheuvel 66cffa6525 EmbeddedPkg/NorFlashInfoLib: convert to BASE library
The library's MODULE_TYPE and the module type restrictions it
defines are needlessly strict. Just change the library to BASE
type and drop the restrictions entirely. Also, drop a bogus
library dependency on DxeServicesLib.
