Irene Park c8edb70945 ArmPlatformPkg/PL011UartLib: Check PID2 if FiFoDepth is zero
PL011UartLib determines its FIFO depth based on the PID2 value but
the register PID2 is not mandatory as per the SBSA spec.
This change won't check PID2 if PcdUartDefaultReceiveFifoDepth is set
to a value > 0.

Ard Biesheuvel de15e7c265 ArmPlatformPkg: remove PL180 SD controller driver
The PL180 SD host controller driver is only used on emulated ARM
platforms, uses an obsolete version of the MMC host protocol and
does not adhere to the UEFI driver model.

It has been moved into edk2-platforms alongside the only platforms
that use it, so we can drop it from the EDK2 core repository.

Ard Biesheuvel 2a7a1223d0 EmbeddedPkg: rename gEfiMmcHostProtocolGuid to gEmbeddedMmcHostProtocolGuid
In EDK2, identifiers carrying the EFI prefix are reserved for ones
that are defined in the UEFI or PI specifications.

Since the MMC host protocol defined in EmbeddedPkg is not the one that
the UEFI spec defines, and given the confusion around this, let's rename
it to from gEfiMmcHostProtocolGuid to gEmbeddedMmcHostProtocolGuid.

Ard Biesheuvel 492679a55d ArmPlatformPkg/PrePi: replace set/way cache ops with by-VA ones
Cache maintenance operations by set/way are only intended to be used
in the context of on/offlining a core, while it has been taken out of
the coherency domain. Any use intended to ensure that the contents of
the cache have made it to main memory is unreliable, since cacheline
migration and non-architected system caches may cause these contents
to linger elsewhere, without being visible in main memory once the
MMU and caches are disabled.

In KVM on Linux, there are horrid hacks in place to ensure that such
set/way operations are trapped, and replaced with a single by-VA
clean/invalidate of the entire guest VA space once the MMU state
changes, which can be costly, and is unnecessary if we manage the
caches a bit more carefully, and perform maintenance by virtual
address only.

So let's get rid of the call to ArmInvalidateDataCache () in the
PrePeiCore startup code, and instead, invalidate the UEFI memory
region by virtual address, which is the only memory region we will
be touching with the caches and MMU both disabled and enabled.
(This will lead to data corruption if data written with the MMU off
is shadowed by clean, stale cachelines that stick around when the
MMU is enabled again.)

Laszlo Ersek e63d54db95 ArmPlatformPkg: convert LFs to CRLF, expand hard TABs
We're going to switch the internal line terminators globally to LF at some
point, but until then, let's use CRLF consistently. Convert source files
with LFs in them to CRLF, using "unix2dos".

"git show -b" prints no code changes for this patch.

(I collected all the file name suffixes in this package, with:

$ git ls-files -- $PACKAGE | rev | cut -f 1 -d . | sort -u | rev

I eliminated those suffixes that didn't stand for text files, then
blanket-converted the rest with unix2dos. Finally, picked up the actual
changes with git-add.)

At the same time, the following file had to undergo TAB expansion:

  ArmPlatformPkg/Scripts/Ds5/profile.py

I used "expand -t 4", conforming to the Indentation section of PEP-8
<https://www.python.org/dev/peps/pep-0008/#indentation>.

Both the CRLF conversion and the TAB expansion are motivated by
"PatchCheck.py". "PatchCheck.py" is also the reason why CRLF conversion
and TAB expansion have to happen in the same patch.

However, the hardware does support the intended usage model, as long

mode involving a handler that is registered by the DXE core and invoked
when the watchdog runs out. In the interrupt handler, we invoke the
notify function if one was registered, before calling the ResetSystem()
runtime service (as per the UEFI spec)

Currently, each flash bank controlled by ArmPlatformPkg/NorFlashDxe

describe each bank to the driver, along with the GUID for each.

This works ok for bare metal platforms, but it would be useful for
virtual platforms if we could obtain this information from a
device tree, which would require us to invent GUIDs on the fly,
given that the 'cfi-flash' binding does not include a GUID.

So instead, let's switch to a single GUID for all flash banks,
and update the driver's device path handling to include an index
to identify each bank uniquely.

case.  There is also an unfortunate lack of control on the placement of
the framebuffer.

This change introduces two PCDs, PcdArmLcdFrameBufferBase and
PcdArmLcdFrameBufferSize which enable build time reservation of the
framebuffer, avoiding the need to allocate dynamically. This allows
the framebuffer to appear as "I/O memory" outside of the normal RAM
map, which is similar to the "VRAM" case.

This change has no impact on current code, only enables the option
of build time reservation of framebuffers.

Girish Pathak 268aad6744 ArmPlatformPkg: PCD to swap red/blue format for HDLCD
This change adds a new PCD PcdArmHdlcdSwapBlueRedSelect
to swap values for HDLCD RED_SELECT and BLUE_SELECT registers
on platforms where blue and red hardware lines are swapped.

If set to TRUE in the platform dsc, HDLCD library will swap the values
while setting RED_SELECT and BLUE_SELECT registers. The default
value of the PCD is FALSE.

NOTE: The motive for this is that a discrepancy in the Red/Blue lines
exists between some VersatileExpress platforms.  Rather than have
divergent code, this build switch allows a simple, pragmatic solution.

Girish Pathak fe787dfb0f ArmPlatformPkg: Add PCD to select pixel format
Current HDLCD and PL111 platform libraries do not support display modes
with PixelBlueGreenRedReserved8BitPerColor format, i.e. because of
historical confusion, they do not support the UEFI default
PixelBlueGreenRedReserved8BitPerColor format

In LcdPlatformLib for PL111, LcdPlatformQueryMode returns the pixel
format as PixelRedGreenBlueReserved8BitPerColor which is wrong, because
that does not match the display controller's pixel format which is set
to BGR in PL111Lcd LcdHwLib.

Also it is not possible to configure pixel format as RGB/BGR for the
display modes for a platform at build time.

This change adds PcdGopPixelFormat to configure pixel format as
    PixelRedGreenBlueReserved8BitPerColor    or
    PixelBlueGreenRedReserved8BitPerColor    or
    PixelBitMask.
With this change, pixel format can be selected in the platform specific
.dsc file for all supported display modes.

Support for PixelBitMask is not implemented in PL111 or HDLCD LcdHwLib
libraries, hence  HDLCD and PL111 platform libraries will return error
EFI_UNSUPPORTED if PcdGopPixelFormat is set to PixelBitMask.  Indeed,
it is not clear what selecting PixelBitMask might mean, but the option
is allowed as it might suit a custom platform.

the Real Time Clock Arch Protocol, without which UEFI drivers cannot be

The PL031RealTimeClockLib instance calls gDS->SetMemorySpaceAttributes()
in the LibRtcInitialize() public function. This DXE service depends on the
CPU Arch Protocol. Add it to the depex.

Laszlo Ersek 6281a2ed3b ArmPlatformPkg/NorFlashDxe: cue the variable driver with NvVarStoreFormatted
The BEFORE depex opcode that we currently use to force ourselves in front
of the variable driver cannot be combined with other depex opcodes.
Replace the depex with TRUE, and signal NvVarStoreFormattedLib through the
installation of "gEdkiiNvVarStoreFormattedGuid".

Platforms that rely on NorFlashDxe to format the variable store (as
opposed to formatting a variable store template through an FDF file, as
part of the build) should hook NvVarStoreFormattedLib into the variable
drivers they use, so that the latter await our cue.

Laszlo Ersek 0f87c53d0d ArmPlatformPkg/NorFlashDxe: initialize varstore headers eagerly
The lazy initialization of the varstore FVB makes no longer sense at this
point:

- "mNorFlashInstanceTemplate.Initialize" is NULL;

- in NorFlashCreateInstance(), we only set Instance->Initialize to
  non-NULL -- namely NorFlashFvbInitialize() -- if the FVB stands for the
  variable store (see "ContainVariableStorage" / "SupportFvb");

- we call Instance->Initialize() from three places:

  - from NorFlashWriteSingleBlock(), which is too late for the variable
    read service ("variable write" depends on "variable read");

  - from InitializeFvAndVariableStoreHeaders(), but that is only reachable
    from NorFlashFvbInitialize(), i.e. recursively from
    Instance->Initialize() itself;

  - and from FvbRead(), which is never called by the variable driver, only
    by the FTW driver. However, the variable driver may read (not write)
    the memory-mapped varstore flash chip before the FTW driver is
    dispatched.

Therefore the lazy initialization is both superfluous and insufficient.
Initialize the varstore headers eagerly, before we install the FVB
protocol interface.

Ard Biesheuvel 44d2e8d7ca ArmPlatformPkg/MemoryInitPeiLib: reserve rather than remove FV memory
Instead of completely removing the memory occupied by the primary PrePi
FV from the memory map, thereby making it inaccessible to the OS, mark
it as boot services data. This will ensure that the memory is left
untouched by the firmware, but will release it to the OS when it calls
ExitBootServices().

Note that for reasons that are not entirely clear, this only works as
desired if the memory allocation HOB and the resource descriptor HOB
that describe the region are identical in offset and size, and so we
still need to iterate over the descriptors and split them up.
