Before CPU enters standby state (wfi), the AP needs to signal the SCP
through PSCI mailbox.

Also at boot time the AP has to wait for the SCP to be ready before
sending the first scpi commands or it can crash.

NOTE: AARCH32/AARCH64 macros are now deprecated in favor of __aarch64__.

All common C compilers pre-define the same macros to signal which
architecture the code is being compiled for: __arm__ for AArch32 (or
earlier versions) and __aarch64__ for AArch64. There's no need for TF-A
to define its own custom macros for this. In order to unify code with
the export headers (which use __aarch64__ to avoid another dependency),
let's deprecate the AARCH32 and AARCH64 macros and switch the code base
over to the pre-defined standard macro. (Since it is somewhat
unintuitive that __arm__ only means AArch32, let's standardize on only
using __aarch64__.)

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.

At the time of writting, GCC 8.3-2019.03 is the latest version available
on developer.arm.com.

Switch to bare-metal toolchain (arm-eabi-) for AArch32. This allows to
have a finer control on the use of floating-point and SIMD instructions.

Fix the typo "warn" -> "warm".

Also fix the following checkpatch.pl warnings:

  CHECK: Prefer using the BIT macro
  CHECK: No space is necessary after a cast
  CHECK: Alignment should match open parenthesis
  CHECK: Unnecessary parentheses around uniphier_io_policies[image_id].dev_handle

Use the helper in utils_def.h instead of the own macro.

This is treated as an error since commit 93c690eb

Only the actual errors are being tackled by this patch. It is up to the
platform to choose whether there needs to be further modifications to
the code.

Add support for multiple Cryptocell revisions which
use different APIs.

This commit only refactors the existing code in preperation to the addition
of another Cryptocell revisions later on.

Code using Cryptocell specific APIs was used as part of the
arm common board ROT support, instead of being abstracted
in Cryptocell specific driver code, creating two problems:
- Any none arm board that uses Cryptocell wuld need to
  copy and paste the same code.
- Inability to cleanly support multiple versions of Cryptocell
  API and products.

Move over Cryptocell specific API calls into the Cryptocell
driver, creating abstraction API where needed.

* changes:
  Refactor SPSR initialisation code
  SSBS: init SPSR register with default SSBS value

* changes:
  plat/mediatek/mt81*: Use new bl31_params_parse() helper
  plat/rockchip: Use new bl31_params_parse_helper()
  Add helper to parse BL31 parameters (both versions)
  Factor out cross-BL API into export headers suitable for 3rd party code
  Use explicit-width data types in AAPCS parameter structs
  plat/rockchip: Switch to use new common BL aux parameter library
  Introduce lightweight BL platform parameter library

The Mediatek MT8173/MT8183 SoCs are prime candidates for switching to
the new bl31_params_parse() helper, so switch them over. This will allow
BL2 implementations on these platforms to transparently switch over to
the version 2 parameter structure.

This patch introduces an additional precautionary step to further
enhance protection against variant 4. During the context initialisation
before we enter the various BL stages, the SPSR.SSBS bit is explicitly
set to zero. As such, speculative loads/stores are by default disabled
for all BL stages when they start executing. Subsequently, each BL
stage, can choose to enable speculative loads/stores or keep them
disabled.

This change doesn't affect the initial execution context of BL33 which
is totally platform dependent and, thus, it is intentionally left up to
each platform to initialise.

For Arm platforms, SPSR.SSBS is set to zero for BL33 too. This means
that, for Arm platforms, all BL stages start with speculative
loads/stores disabled.
