johpow01 3a2710dcab Workaround for Cortex A78 erratum 1951500
Cortex A78 erratum 1951500 is a Cat B erratum that applies to revisions
r0p0, r1p0, and r1p1.  The workaround is to insert a DMB ST before
acquire atomic instructions without release semantics.  This workaround
works on revisions r1p0 and r1p1, in r0p0 there is no workaround.

Javier Almansa Sobrino 1994e56221 arm_fpga: Add support for unknown MPIDs
This patch allows the system to fallback to a default CPU library
in case the MPID does not match with any of the supported ones.

This feature can be enabled by setting SUPPORT_UNKNOWN_MPID build
option to 1 (enabled by default only on arm_fpga platform).

This feature can be very dangerous on a production image and
therefore it MUST be disabled for Release images.

The DSU contains system control registers in the SCU and L3 logic to
control the functionality of the cluster. If "DIRECT CONNECT" L3
memory system variant is used, there won't be any L3 cache,
snoop filter, and SCU logic present hence no system control register
will be present. Hence check SCU presence before accessing DSU register
for DSU_936184 errata.

Masahiro Yamada 9cefb4b194 Pass more -D options to BL*_CPPFLAGS instead of BL*_CFLAGS
Commit d5e97a1d2c ("Build: define IMAGE_AT_EL1 or IMAGE_AT_EL3
globally for C files") does not have commit 848a7e8ce1 ("Build:
introduce per-BL CPPFLAGS and ASFLAGS") as an ancestor because
they were pulled almost at the same time.

This is a follow-up conversion to be consistent with commit
11a3c5ee73 ("plat: pass -D option to BL*_CPPFLAGS instead of
BL*_CFLAGS").

With this change, the command line option, IMAGE_AT_EL3, will be
passed to .S files as well.

I remove the definition in include/lib/cpus/aarch64/cpu_macros.S

Otherwise, the following error would happen.

  include/lib/cpus/aarch64/cpu_macros.S:29:0: error: "IMAGE_AT_EL3" redefined [-Werror]

Varun Wadekar cd0ea1842f cpus: higher performance non-cacheable load forwarding
The CPUACTLR_EL1 register on Cortex-A57 CPUs supports a bit to enable
non-cacheable streaming enhancement. Platforms can set this bit only
if their memory system meets the requirement that cache line fill
requests from the Cortex-A57 processor are atomic.

This patch adds support to enable higher performance non-cacheable load
forwarding for such platforms. Platforms must enable this support by
setting the 'A57_ENABLE_NONCACHEABLE_LOAD_FWD' flag from their
makefiles. This flag is disabled by default.

Julius Werner d5dfdeb65f Replace __ASSEMBLY__ with compiler-builtin __ASSEMBLER__
NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

lauwal01 11c48370bd Workaround for Neoverse N1 erratum 1262888
Neoverse N1 erratum 1262888 is a Cat B erratum [1],

The workaround is to set a bit in the implementation defined
CPUECTLR_EL1 system register, which disables the MMU hardware prefetcher.

Antonio Nino Diaz ff6f62e105 Update macro to check need for CVE-2017-5715 mitigation
Armv8.5 introduces the field CSV2 to register ID_AA64PFR0_EL1. It can
have the following 3 values:

- 0: Branch targets trained in one hardware described context may affect
     speculative execution in a different hardware described context. In
     some CPUs it may be needed to apply mitigations.

- 1: Branch targets trained in one hardware described context can only
     affect speculative execution in a different hardware described
     context in a hard-to-determine way. No mitigation required.

- 2: Same as 1, but the device is also aware of SCXTNUM_ELx register
     contexts. The TF doesn't use the registers, so there is no
     difference with 1.

The field CSV2 was originally introduced in the TRM of the Cortex-A76
before the release of the Armv8.5 architecture. That TRM only mentions
the meaning of values 0 and 1. Because of this, the code only checks if
the field has value 1 to know whether to enable or disable the
mitigations.

This patch makes it aware of value 2 as well. Both values 1 and 2
disable the mitigation, and 0 enables it.

Antonio Nino Diaz a69817eda2 cpus: Fix some incorrect definitions in CPU headers
There are some values that should be 64-bit immediates but that resolve
to 0 because the type of the value is 32-bit wide. This patch casts the
expressions to 64-bit before the shift so that the definition has the
correct value.

The definitions are only used in assembly so far, so the code is not
actually affected by this bug. The assembler treats all values as 64-bit
values, so there are no overflows.

Antonio Nino Diaz 09d40e0e08 Sanitise includes across codebase
Enforce full include path for includes. Deprecate old paths.

The following folders inside include/lib have been left unchanged:

- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}

The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).

For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.

Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Antonio Nino Diaz c3cf06f1a3 Standardise header guards across codebase
All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers
