* EmbeddedPkg/PrePiHobLib: replace duplicate GUIDMatthew Carlson2021-03-161-1/+1

* EmbeddedPkg: Only print LibGetTime message about compile time epoch onceRebecca Cran2021-03-081-1/+9
| | | | | | | | | | | | | | | | | | | | 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 44ae214591e58af468eacb7b873eaa0bc187c4fa 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.

* EmbeddedPkg/TimeBaseLib: remove useless truncation to 32-bitLaszlo Ersek2020-12-211-3/+3
| | | | | | | | | | | | | | | | | | | EfiTimeToEpoch() calls EfiGetEpochDays() internally, which (reasonably) returns a UINTN. But then EfiTimeToEpoch() truncates the EfiGetEpochDays() retval to UINT32 for no good reason, effectively restricting Time->Year under 2106. This truncation was pointed out with a valid warning (= build error) by VS2019. Allow EfiTimeToEpoch() to return / propagate a UINTN value.

* EmbeddedPkg/VirtualRealTimeClockLib: Explicit cast to UINT32Pete Batard2020-10-221-2/+2
| | | | | | | | | | | | | | | | | 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. Signed-off-by: Pete Batard <pete@akeo.ie> Reviewed-by: Ard Biesheuvel <ard.biesheuvel@arm.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | For the LoadImage() boot service, with EFI_SECURITY_VIOLATION retval, 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 the execution of an image, we can not treat EFI_SECURITY_VIOLATION 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 for the callers in EmbeddedPkg which don't have the policy to defer the execution of the image.

* EmbeddedPkg: introduce NvVarStoreFormattedLibLaszlo Ersek2018-04-122-0/+93
| | | | | | | | | | | | | | | | | | | | | | | | | | | Some platforms don't format a variable store template at build time; instead they format the non-volatile varstore flash chip during boot, dynamically. Introduce NvVarStoreFormattedLib to enable such platforms to delay the "variable read" service drivers until the platform specific module(s) report that the variable store has been formatted. The platform-specific module that performs the formatting during startup is usually an FVB or MM FVB driver. Under the proposed scheme, it becomes responsible for installing gEdkiiNvVarStoreFormattedGuid with a NULL interface in the protocol database. In turn, the platform DSC will hook NvVarStoreFormattedLib into the variable service driver, to make the latter wait for the FVB driver. Platforms that need not delay the variable service driver like this may still use the same FVB driver; gEdkiiNvVarStoreFormattedGuid will simply be ignored.

* EmbeddedPkg BeagleBoardPkg: move special HOB reuse libraries into platformArd Biesheuvel2017-11-304-432/+0
| | | | | | | | | | | | | | The BeagleBoard platform uses PeCoffLib and CustomDecompressLib implementations that invoke the library code that resides in the PrePi module via pointers exposed via special GUIDed HOBs. This is a nice hack, but not necessarily something we want to carry in reference code. So as a first step, move the libraries that expose this reused code into BeagleBoardPkg, and remove it from EmbeddedPkg.

| | | | | | | | | | | EBL is a deprecated, small memory footprint alternative for the UEFI Shell that is no longer in use by any platforms in EDK2 or in edk2-platforms. To avoid confusion, let's remove it from the tree.

| | | | | | | | | | | | | The sum use these applications made of BdsLib was one invocation of the IS_DEVICE_PATH_NODE macro, and (incorrectly) being able to leave out a dependency on gEfiLoadedImageProtocolGuid. So expand the macro in place and add the missing dependency. Then clean up the .dsc, .inf and #includes accordingly.

* EmbeddedPkg: Implement NorFlashInfoLibMarcin Wojtas2017-11-072-0/+259
| | | | | | | | | | | | | | | | | | | | | | | | | The SPI NOR flash drivers which base on ArmPlatformPkg's NorFlashDxe usually make use of static declarations of the flash instances with their type and parameters. As a result it implies hardcoding the exact way of flash handling, not to mention the code does not look very nice. Much better solution would be obtaining the flash ID and hence its description in runtime. JEDEC compliant SPI NOR devices allow to obtain their IDs with READ_ID command (0x9f), which should return the vendor ID byte, followed by 2 to 4 following device ID bytes. Use this capability for implementing a NorFlashInfoLib that gives an access to the NOR flash description data, such as name, page size, sector (block) size and others, of more than 50 different models. The new library user should pass an output array from issuing READ_ID command to the NorFlashGetInfo () routine - if the match is found, an allocated (optionally for RT) pool with the flash description copy will be returned.
