Pete Batard 6c1fb56802 EmbeddedPkg/AcpiLib: add GICC table init macro for ACPI 6.3
ACPI 6.3 added a 16-bit SPE overflow Interrupt field, replacing
2 of the 3 reserved bytes that are defined at the end of the
GICC structure for 6.0.

Add a new macro to initialise the new field.

needs to locate GPIO protocol if he wants to simulate a GPIO value

Laszlo Ersek 7ab26d5180 EmbeddedPkg: introduce NvVarStoreFormattedLib
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.

Ard Biesheuvel 44e6186eea EmbeddedPkg/FdtLib: incorporate missing overlay support
Commit a099239015 ("EmbeddedPkg/FdtLib: Update FdtLib to v1.4.5")
updated our FdtLib implementation to a more recent upstream version,
but omitted fdt_overlay.c due to its ambiguous licensing situation.
This has been resolved now, so take the latest upstream version of
the file (which received no other modifications in the mean time)
and add it to FdtLib.

Note that fdt_overlay.c has a dependency on strtoul() which EDK does
not provide natively, so add a private implementation that wraps the
BaseLib routines that do roughly the same.

Marcin Wojtas 7046610163 EmbeddedPkg: Implement NorFlashInfoLib
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.

Note that the naming is slightly awkward, as there is nothing 'embedded'

So let's introduce a driver that allows the user to set a 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.

Laszlo Ersek 65a69b2148 EmbeddedPkg: introduce EDKII Platform Has Device Tree GUID
The presence of this GUID in the PPI database, and/or in the DXE protocol
database (as dictated by the platform's needs in these firmware phases)
implies that the platform provides the operating system with a Device
Tree-based hardware description. This is not necessarily exclusive with
other types of hardware description (for example, an ACPI-based one).

A platform PEIM and/or DXE driver is supposed to produce a single instance
of the PPI and/or protocol (with NULL contents), if appropriate. The
decision to produce the PPI and/or protocol is platform specific; for
example, in the DXE phase, it could depend on an HII checkbox / underlying
non-volatile UEFI variable.

In the DXE phase, the protocol is meant to be consumed by the platform
driver that
- owns the Device Tree description of the hardware, and
- is responsible for installing it as a system configuration table.

Said FDT-owner driver can wait for the protocol via DEPEX or protocol
notify.

Because this GUID is not standard, it is prefixed with EDKII / Edkii, as
seen elsewhere (for example in MdeModulePkg and SecurityPkg).

The presence of this GUID in the PPI database, and/or in the DXE protocol

implies that the platform provides the operating system with an ACPI-based
hardware description. This is not necessarily exclusive with other types

decision to produce the PPI and/or protocol is platform specific; for
example, in the DXE phase, it could depend on an HII checkbox / underlying
non-volatile UEFI variable.

In the DXE phase, the protocol is meant to be depended-upon by
"MdeModulePkg/Universal/Acpi/AcpiTableDxe", indirectly:

* In the long term, interested platforms will establish this dependency by
  hooking an (upcoming) NULL-class DepexLib instance into AcpiTableDxe in
  their DSC files, pointing DepexLib's DEPEX through a FixedAtBuild PCD to
  the GUID introduced here. (For the prerequisite BaseTools feature, refer
  to <https://bugzilla.tianocore.org/show_bug.cgi?id=443>).

* In the short term, an interested platform may hook a private NULL-class
  library instance (called e.g. "PlatformHasAcpiLib") into AcpiTableDxe.
  Such a library instance would be a specialization of the above described
  generic DepexLib, with the DEPEX open-coded on the GUID introduced here.

Either way, the platform makes EFI_ACPI_TABLE_PROTOCOL and (if enabled)
EFI_ACPI_SDT_PROTOCOL dependent on the platform's dynamic decision to
produce or not to produce a NULL protocol instance with this GUID.

In turn, other (platform and universal) DXE drivers that produce ACPI
tables will wait for EFI_ACPI_TABLE_PROTOCOL / EFI_ACPI_SDT_PROTOCOL, via
DEPEX, protocol notify, or a simple gBS->LocateProtocol() in a "late
enough" callback (such as Ready To Boot).

Because this GUID is not standard, it is prefixed with EDKII / Edkii, as
seen elsewhere in MdeModulePkg and SecurityPkg. In addition, an effort is
made to avoid the phrase "AcpiPlatform", as that belongs to drivers /
libraries that produce platform specific ACPI content (as opposed to
deciding whether the entire firmware will have access to
EFI_ACPI_TABLE_PROTOCOL, or any similar facilities in the PEI phase).

This has been seen using Cygwin, MinGW and PowerShell Git.

This patch makes no change to source file content, and only aims to
correct the file modes/permissions.

Thomas Palmer 50c6a4d2d4 EmbeddedPkg: Add EFIAPI to several Ebl functions
The EFIAPI function declaration is missing for several functions in the
EmbeddedPkg/Ebl directory. A few function pointer struct members expect
EFIAPI though and GCC46/X64 will fail to compile the directory without
them.

Ard Biesheuvel cc667df08a ArmVirtualizationPkg: use a HOB to store device tree blob
Instead of using a dynamic PCD, store the device tree address in a HOB
so that we can also run under a configuration that does not support
dynamic PCDs.

This also adds MemoryAllocationLib to the [LibraryClasses] section of
ArmVirtualizationPlatformLib/ArmVirtualizationPlatformLib.inf, as this
dependency was formerly satisfied transitively through one of the
library dependencies that were dropped.
