Ard Biesheuvel 971a2d520e ArmPlatformPkg/ArmVExpressDxe: remove FDT handling from ArmFvpDxe
Replace the elaborate but awkward handling of FDT images using device
paths and string PCDs initialized to 128 spaces with a simple scheme
involving a set of builtin DTBs and a bit of runtime logic to select
between them.

This is sufficient for ordinary use, which makes it more suitable as
reference code. Note that overriding the DTB presented to the OS can
easily be done with a UEFI application that simply installs a new DTB
image under the existing FDT configuration table GUID.

For this module, this simply involves removing all code that is involved
in deciding which platform we are running on, and for reasoning about
FDT device paths.

Ard Biesheuvel a30d5f9f90 ArmPlatformPkg/PL111LcdArmVExpressLib: use write-combine mapping for VRAM
Replace the uncached memory mapping of the framebuffer with a write-
combining one. This improves performance, and avoids issues with

Instead of manipulating the memory attributes directly, use the

against the capabilities of the region before making the actual change.

Ard Biesheuvel 1344c8c605 ArmPlatformPkg/FVP: map motherboard VRAM as uncached memory
The VRAM of the PL111 on the FVP Base/Foundation models is described as
device memory rather than uncached memory, which is not an accurate
description of the nature of the region (i.e., a framebuffer), and may
result in problems when using accelerated string routines to access the
region, since this may legally involve unaligned accesses or DC ZVA
instructions, which are not allowed on device mappings.

So split of the 8 MB VRAM region into a separate region, and map it using
memory attributes.

of the link register, and simplify/deobfuscate the calculation of the
secondary stack position.

(*) Note that r3 is not actually a callee saved register even on ARM.

Bhupesh Sharma 465663e9f1 ArmPlatformPkg/TZASC: Allow specifying subregions to be disabled
ARM TZASC-380 IP provides a mechanism to split memory regions being
protected via it into eight equal-sized sub-regions. A bit-setting
allows the corresponding subregion to be disabled.

Several NXP/FSL SoCs support the TZASC-380 IP block and allow
the DDR connected via the TZASC to be partitioned into regions
having different security settings and also allow subregions
to be disabled.

This patch enables this support and can be used for SoCs which
support such a partition of DDR regions.

Flash commands might never reach the device.

Ard Biesheuvel 4aae7419ee ArmPlatformPkg/PrePi: avoid global variable write to mSystemMemoryEnd
The global variable mSystemMemoryEnd is initialized by PrePi only if
it has not been initialized by ArmPlatformPeiBootAction(). This allows
platforms executing under, e.g., ARM Trusted Firmware to dynamically
reserve a window at the top of memory that will be used by the secure
firmware.

However, PrePi is a SEC module, and writing to a global variable
violates the SEC constraints, since SEC and PEI may execute from NOR
flash.

So instead, initialize mSystemMemoryEnd statically. This will ensure
it holds the correct value for all implementations where the value
is not overridden, but still allows it to be overridden during the
call to ArmPlatformPeiBootAction().

Note that this patch also fixes a latent bug on 32-bit platforms where
a value of mSystemMemoryEnd exceeding 4 GB would be truncated to 32-bits
rather than limited to (4 GB - 1)

Alexei a4bcf0bcdd ArmPlatformPkg: Remove UINTN cast when setting BaudRate.
SerialPortInitialize() set the BaudRate variable (type UINT64) as:
BaudRate = (UINTN)FixedPcdGet64 (PcdUartDefaultBaudRate);

This commit fixes a potential problem on ARM 32-bit builds, where the
UINTN type is defined as UINT32, by removing the cast:

BaudRate = FixedPcdGet64 (PcdUartDefaultBaudRate);

Evan Lloyd 719a347c5d ArmPlatformPkg: Fix PL011 FIFO size test
This change updates PL011UartInitializePort to compare ReceiveFifoDepth
with the correct hardware FIFO size instead of the constant 32 used
previously.
This corrects a minor bug where a request for a fifo size > 15 and < 32
would not have been honoured on a system with a 16 byte FIFO.

Ard Biesheuvel bdb10148fc ArmPlatformPkg/NorFlashDxe: use strictly aligned CopyMem()
The UEFI spec stipulates that unaligned accesses should be enabled
on CPUs that support them, which means all of them, given that we
no longer support pre-v7 ARM cores, and the AARCH64 bindings mandate
support for unaligned accesses unconditionally.

This means that one should not assume that CopyMem () is safe to call
on regions that may be mapped using device attributes, which is the
case for the NOR flash. Since we have no control over the mappings when
running under the OS, and given that write accesses require device
mappings, we should not call CopyMem () in the read path either, but
use our own implementation that is guaranteed to take alignment into
account.

Ard Biesheuvel d74135cd0f ArmPlatformPkg: remove EFI_MEMORY_UC attribute from normal memory
On ARM systems, mapping normal memory as device memory may have unintended
side effects, given that unaligned accesses or loads and stores with special
semantics (e.g., load/store exclusive) may fault or may not work as expected.
Similarly, DC ZVA instructions are only supported on normal memory, not
device memory.

So remove the EFI_MEMORY_UC attribute that we set by default on system RAM.
If any region requires this attribute, it is up to the driver to set this
attribute, and to ensure that no offending operations are performed on it.

According to the ACPI 6.0/6.1 spec, the physical base address of GICC,
GICD, GICR and GIC ITS is 64-bit. So change the type of the various GIC
base address PCDs to 64-bit, and fix up all users.
