Ard Biesheuvel 62a75650e4 EmbeddedPkg/NonCoherentDmaLib: implement support for DMA range limits
Implement support for driving peripherals with limited DMA ranges to
NonCoherentDmaLib, by adding a device address limit, and taking it,
along with the device offset, into account when allocating or mapping
DMA buffers.

Dandan Bi 82e0c422b2 EmbeddedPkg: Unload image on EFI_SECURITY_VIOLATION
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.

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

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.

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.

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.

This has been resolved now, so take the latest upstream version of

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.

Ard Biesheuvel 723102c72f EmbeddedPkg: implement NonCoherentDmaLib based on ArmDmaLib
The non-coherent DmaLib implementation in ArmDmaLib no longer relies on
anything in ArmPkg. So clone it into EmbeddedPkg, and rename it to
NonCoherentDmaLib.

Ard Biesheuvel 7385d2543e EmbeddedPkg: rename NullDmaLib to CoherentDmaLib
The name NullDmaLib suggests that this library is a placeholder that
only exists to fulfil formal dependencies on the DmaLib library class
without providing an actual implementation. This is not the case, though:
NullDmaLib does implement DmaLib fully, but doing so simply requires very
little effort on a cache coherent platform. So let's rename it to
CoherentDmaLib instead.

Ard Biesheuvel deef290f95 EmbeddedPkg/DmaLib: add routine to allocate aligned buffers
DmaLib's purpose is to manage memory that is shared between the host
and DMA capable devices. 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.

Ard Biesheuvel 6ac97ad31e EmbeddedPkg/PrePiLib: allocate code pages for DxeCore
The recently introduced memory protection features inadvertently broke
the boot on all PrePi platforms, because the changes to explicitly use
EfiBootServicesCode for loading the DxeCore PE/COFF image need to be
applied in a different way for PrePi. So add a simple helper function
that sets the type of an allocation to EfiBootServicesCode, and invoke
it to allocate the space for DxeCore.
