* EmbeddedPkg: Fix some spelling mistakes found by cspellRebecca Cran2024-08-011-1/+1
| | | | | | | | | | | When cspell is installed (via `npm install cspell`), CI checks for spelling mistakes. There are currently a very large number of them: some are genuine mistakes while others are words or acryonyms that cspell doesn't know. Fix a few of the misspellings in EmbeddedPkg.

* EmbeddedPkg: Add option to disable EFI Memory Attribute ProtocolMario Bălănică2024-07-161-0/+17
| | | | | | | | | | | | | | | | | | | | | Introduce a driver that allows users to disable the EFI Memory Attribute protocol through an HII setup option, in order to work around a broken version of rhboot's shim used in some distros (e.g. CentOS Stream 9) which incorrectly invokes the protocol and results in a Synchronous Exception. Default is enabled, which can also be overridden at build time by changing `gEmbeddedTokenSpaceGuid.PcdMemoryAttributeEnabledDefault`. It is only applicable to ARM64 and there isn't any other technical reason for disabling this security feature.

* EmbeddedPkg/RealTimeClockLib: drop LibRtcVirtualNotifyEvent from lib classLaszlo Ersek2023-10-181-15/+0
| | | | | | | | | | | | | | | | | | | | | | | The RealTimeClockLib class header in edk2 mistakenly declares a function called LibRtcVirtualNotifyEvent(). No component ever calls this function crossing module boundaries; all RealTimeClockLib instances in edk2 and edk2-platforms are supposed to register (and do register) their SetVirtualAddressMap() notification functions. At this point, the word "LibRtcVirtualNotifyEvent" no longer occurs in any of edk2, edk2-platforms, even edk2-non-osi, except the library class header proper. Remove the LibRtcVirtualNotifyEvent() function declaration. Build-tested only (with "EmbeddedPkg.dsc").

| | | | | | | | | | | | | | | | | | | | | | | | | | | | For the implementation which utilizes libfdt provided in EmbeddedPkg however it uses strncmp function in the libfdt helper library, libfdt_env.h should provide the macro implied with edk2 strncmp implementation. The example is RISC-V OpenSBI library. edk2 RISC-V port uses OpenSBI library and incorporate with edk2 libfdt. edk2 libfdt_env.h provides the necessary macros to build OpenSBI which uses fdt functions in edk2 environment. However, OpenSBI also has libfdt helper library that uses strncmp function which is not defined in edk2 libfdt_env.h.

| | | | | | | | | | | | | | | | | | These can be used, for instance, to automate the population of an SMBIOS Type 0 BIOS Release Date when building a UEFI firmware (which is how we plan to use these macros for the Raspberry Pi platform). These macros should work for any compiler that follows ISO/IEC 9899, but we add a check for the compiler we have tested to be on the safe side. Note that we decided against adding a #error or #warn for compilers that haven't been validated, as we don't want to introduce breakage for people who may already be using the header with something else than gcc, MSVC or Clang. Instead, we expect those to send a patch that adds their compiler to the list, once they have tested the macros there.

* EmbeddedPkg: introduce NvVarStoreFormattedLibLaszlo Ersek2018-04-121-0/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

To avoid confusion, let's remove it from the tree.

* EmbeddedPkg: Implement NorFlashInfoLibMarcin Wojtas2017-11-071-0/+96
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* EmbeddedPkg: introduce GPIO PPIArd Biesheuvel2017-11-051-0/+151
| | | | | | | | | | | | | | Introduce a PPI counterpart of the existing 'embedded GPIO' protocol, so we can manipulate GPIOs from PEI modules. This allows things like setting the boot mode based on a DIP switch setting. Note that the naming is slightly awkward, as there is nothing 'embedded' about a GPIO, but given that the DXE protocol already resides here and has the 'embedded' prefix, it makes sense to retain uniformity.

* EmbeddedPkg: add driver to set graphical/serial console preferenceArd Biesheuvel2017-10-231-0/+23
| | | | | | | | | | | | | | | | Linux on ARM/arm64 will infer from the presence of a /chosen/stdout-path DT property or of a SPCR ACPI table that the primary console is the serial port, even if a graphical console is available as well. So let's introduce a driver that allows the user to set a preference between graphical and serial if both are available. If the preference is set to 'Graphical', and any GOP protocol instances have been installed by the time the ReadyToBoot event is signalled, remove the DT property and/or the SPCR table entirely.

In some cases, this requires a larger alignment than page size, and we currently don't cater for that in DmaLib. So add a variant of DmaAllocateBuffer () that takes an alignment parameter.
