From: Ard Biesheuvel <ard.biesheuvel@linaro.org>
This change fixes incorrect MODULE_TYPE of HDLCD and PL111
LcdPlatformLibs. Currently set MODUL_TYPE DXE_DRIVER is incorrect
for these platform libraries. Hence set this to type BASE.

There is no functional modification in this change.
In this change some comments in HDLCD and PL111LCD platform library
code are modified and a few new comments are added. This is to
prevent mixing formatting changes with functional changes.

PCD PcdPL111LcdMaxMode is not used in HDLCD platform library.
Presence of this PCD in HDLCD is probably due to copy/paste code
from PL111 Lcd platform library. This change removes it from
the HdLcdArmVExpressLib.inf file.

This change adds some debug assertions e.g to catch NULL pointer errors
missing in PL11Lcd and HdLcd platform libraries.

None of the ArmPlatformSys* functions returns EFI_TIMEOUT. Hence checking
this in the do {} while loop in LcdPlatformSetMode is wrong. Therefore
remove this comparision and as a result remove the do {} while loop.

Because of copy/paste effects, HdLcdArmVExpress.c contained a
table entry "LCD_BPP Bpp;" specifying the Bits per Pixel for each mode.
However, all modes are LCD_BITS_PER_PIXEL_24.
This change removes the table entry and related use of the field.

From: EvanLloyd <evan.lloyd at arm.com>
The LcdPlatformGetTimings interface function takes similar sets of
multiple parameters for horizontal and vertical timings which can be
aggregated in a common data type. This change defines a structure
SCAN_TIMINGS for this which can be used to describe both horizontal and
vertical scan timings, and accordingly redefines the
LcdPlatformGetTiming interface, greatly reducing the amount of data
passed about.
Similarly the mode definition tables are also changed to use this data
type and thus enable pass through access.

From: Girish Pathak <girish.pathak at arm.com>
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
LcdPlatformLib for PL111, LcdPlatformQueryMode function 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 GOP driver.
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
GOP driver, 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.

As per the UEFI specification(2.7) section 12.9, the GOP framebuffer
memory can be accessed in the pre-boot and the post boot phase (by OS)
Therefore the memory type EfiBootServicesData is incorrect for
the framebuffer memory allocation. Change EfiBootServicesData with
EfiRuntimeServicesData flag so that allocated memory can be access
by the OS in the post boot phase.

EfiRuntimeServicesData is intended for allocations that the EFI
runtime services need to access themselves at runtime, and will hence
be virtually remapped by SetVirtualAddressMap().
This does not apply to the framebuffer. Even if it may be used at OS
runtime, the firmware itself will never access it, so
EfiRuntimeServicesData is not appropriate
Please use EfiReservedMemory instead.

Specification (UEFI Spec 2_7_A Sept 6.pdf) describes EfiReservedMemoryType as Not usable before and after ExitBootServices, See Table 28 & 29
Hence EfiReservedMemoryType is not suitable in this case. Agree?

It is not usable as ordinary memory, given that you turn it into
'special' memory (with side effects) by turning it into a framebuffer.
So EfiReservedMemory is perfectly appropriate here.

[[Evan Lloyd]] First, I agree EfiReservedMemory is probably the sensible option. The only alternative would be EfiMemoryMappedIO, and that, as you have pointed out in the past, introduces alignment requirements. If you are happy to accept it, I'll ask Girish to go with that. However, Girish has a point, if only that the UEFI spec need more clarity on this, especially as https://lists.01.org/pipermail/edk2-devel/2017-February/007494.html pretty much confirms it is the right way to go. In particular, the bald statement "EfiReservedMemoryType Not usable.", seems unfortunate.

EfiReservedMemory is the only appropriate type to use here, and if the
spec is unclear, we should fix that.

This change uses two PCDs, PcdArmLcdFrameBufferBase and
PcdArmLcdFrameBufferSize introduced in correspondiong EDK2 patch to
reserve framebuffer in DRAM if these values are defined in platform
specific DSC file, 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.

v3:
- Move PcdArmLcdDdrFrameBufferBase and
PcdArmLcdDdrFrameBufferSize to VExpressPkg. [Ard]
These PCDs are also used for the Juno platform hence these
PCDs are defined for the ArmPlatformPkg so that both
platform can use it. [Girish]
- Could you please add an ASSERT() so that System Memory
and PcdArmLcdDdrFrameBufferBase do not overlap [Ard]
Done [Girish]

The framebuffer memory is set with flag
EFI_MEMORY_WC (uncached, unbuffered) which causes framebuffer memory
with eXecute bit set. Framebuffer memory having executable bit
set is a security hazard. This fix adds EFI_MEMORY_XP flag to avoid this.
Unfortunately function gDS->SetMemorySpaceAttributes() causes assertion due
to unsupported EFI_MEMORY_XP type. Therefore this fix replaces
gDS->SetMemorySpaceAttributes() with Cpu->SetMemoryAttributes().

This change adds LcdPlatformLib implementation for Arm Mali
DP500/DP500/DP650 display processors for models (with DP550 support).
NOTE: Versions for actual hardware are liable to require extra handling
for clock input changes, etc.

This change adds a new Mailbox Transport Layer library for the Juno
platform. This library is required for ArmScmiDxe driver communication
with the SCP.
Contributed-under: TianoCore Contribution Agreement 1.1
Signed-off-by: Girish Pathak <girish.pathak@arm.com>

Notes:
v3:
- Please rename this library *instance* to something
Juno-specific, e.g., ArmJunoMtlLib [Ard]
Renamed to ArmJunoMtlLib [Girish]

This change adds the HDLCD platform lib for the Juno plaform. This
library will be instantiated as a LcdPlatformLib to link with
LcdGraphicsOutputDxe for the Juno platform.
HDLCD platform library depends on the Arm SCMI DXE driver for
communication with the SCP for clock setting. Therefore this change also
enables building of Arm SCMI DXE driver for the Juno platform.

Notes:
v3:
- Wouldn't it make more sense to add a macro
ENABLE_HDLCD, rather than inverting
the logic? [Ard]
We used this to correspond with the ACPI
(FADT) terminology, where HEADLESS implies
more than just no display.
Refer below email [Evan]

- SRAM mapping: Couldn't you map it as
non-cacheable memory instead [Ard]
Done [Girish]
- Please fix weird indentation [Ard]
Done [Girish]
- Please don't use CPP conditionals for
control flow [Ard]
