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.

Remove references to old project name from common files
...
The project has been renamed from "Arm Trusted Firmware (ATF)" to
"Trusted Firmware-A (TF-A)" long ago. A few references to the old
project name that still remained in various places have now been
removed.
This change doesn't affect any platform files. Any "ATF" references
inside platform files, still remain.

fvp: trusty: Move dynamic xlat enable to platform

Rather than letting the Trusty makefile set the option to enable dynamic
translation tables, make platforms do it themselves.
This also allows platforms to replace the implementation of the
translation tables library as long as they use the same function
prototypes.

c_rt_ctx is used to store current SP before the system goes

This patch removes assert(tlk_ctx->c_rt_ctx == 0) from the
System Suspend path, as a result.

tlkd: support new TLK SMCs
...
This patch adds support to handle following TLK SMCs:
{TLK_SS_REGISTER_HANDLER, TLK_REGISTER_NS_DRAM_RANGES, TLK_SET_ROOT_OF_TRUST}
These SMCs need to be supported in ATF in order to forward them to
TLK. Otherwise, these functionalities won't work.
Brief:
TLK_SS_REGISTER_HANDLER: This SMC is issued by TLK Linux Driver to
set up secure storage buffers.
TLK_REGISTER_NS_DRAM_RANGES: Cboot performs this SMC during boot to
pass NS memory ranges to TLK.
TLK_SET_ROOT_OF_TRUST: Cboot performs this SMC during boot to pass
Verified Boot parameters to TLK.

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: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("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.

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

Ensure the flow through switch statements is clear
...
Ensure case clauses:
* Terminate with an unconditional break, return or goto statement.
* Use conditional break, return or goto statements as long as the end
of the case clause is unreachable; such case clauses must terminate
with assert(0) /* Unreachable */ or an unconditional __dead2 function
call
* Only fallthough when doing otherwise would result in less
readable/maintainable code; such case clauses must terminate with a
/* Fallthrough */ comment to make it clear this is the case and
indicate that a fallthrough is intended.
This reduces the chance of bugs appearing due to unintended flow through a
switch statement
