This patch adds support in GPT library for configuration
of the memory block size protected by one bit of 'bitlock'
structure. Build option 'RME_GPT_BITLOCK_BLOCK' defines the
number of 512MB blocks covered by each bit. This numeric
parameter must be a power of 2 and can take the values from
0 to 512. Setting this value to 0 chooses a single spinlock
for all GPT L1 table entries. The default value is set to 1
which corresponds to 512MB per bit.

Most developers run the `clean`, `checkpatch` and other similar targets
without specifying any other additional build options. When combined
with a flow where the developer passes `CROSS_COMPILE` or `CC`
explicitly, and where the default-configured tools are not on the PATH,
these targets will warn about unrecognized toolchain tools.
This change is a workaround for this whereby the toolchain makefile is
not expanded unless a target *not* named `*clean`, `check*` `doc` or
`*tool` has been specified.

This patch adds support for large GPT mappings using
Contiguous descriptors. The maximum size of supported
contiguous block in MB is defined in RME_GPT_MAX_BLOCK
build parameter and takes values 0, 2, 32 and 512 and
by default set to 2 in make_helpers/defaults.mk.
Setting RME_GPT_MAX_BLOCK value to 0 disables use of
Contiguous descriptors.
Function gpt_tlbi_by_pa_ll() and its declaration
are removed from lib/aarch64/misc_helpers.S and
include/arch/aarch64/arch_helpers.h, because the
GPT library now uses tlbirpalos_xxx() functions.

This function causes the build message to be generated and compiled in
two different ways, with one way done inside `build_macros.mk` and the
other done inside `windows.mk`, mostly because it's done by generating
the C file on the command line.
We can instead replace this whole build message generation sequence with
a simple standard C compilation command and a normal C file.

This is a generic porting of what was done on ST platforms with flag
STM32MP_EARLY_CONSOLE. It creates the flag and the prototype for
plat_setup_early_console(). This function depends on platform
implementation. This function call is added at the beginning of each BL
image early setup function.
The patch also introduce an extra log macro: EARLY_ERROR. This can
replace ERROR macro in code that will only be executed before the
default console is enabled, and will do nothing when the EARLY_CONSOLE
is not enabled. This can then save some space in memory.

Access to rdist_ctx and dist_ctx is defined using inline assembler
like
__asm__ volatile ("ldr %0, =rdist_ctx" : "=r" (v) : "X" (rdist_ctx));
Access assembler function definitions moved to a different ltrans then

used symbols in inline assembler. Depending on compiler partitioner
decision the same code builds for some platforms successfully.

This change refactors how we identify the toolchain, with the ultimate
aim of eventually cleaning up the various mechanisms that we employ to
configure default tools, identify the tools in use, and configure
toolchain flags.
To do this, we introduce three new concepts in this change:
- Toolchain identifiers,
- Tool class identifiers, and
- Tool identifiers.
Toolchain identifiers identify a configurable chain of tools targeting
one platform/machine/architecture. Today, these are:
- The host machine, which receives the `host` identifier,
- The AArch32 architecture, which receives the `aarch32` identifier, and
- The AArch64 architecture, which receivs the `aarch64` identifier.
The tools in a toolchain may come from different vendors, and are not
necessarily expected to come from one single toolchain distribution. In
most cases it is perfectly valid to mix tools from different toolchain
distributions, with some exceptions (notably, link-time optimization
generally requires the compiler and the linker to be aligned).
Tool class identifiers identify a class (or "role") of a tool. C
compilers, assemblers and linkers are all examples of tool classes.
Tool identifiers identify a specific tool recognized and supported by
the build system. Every tool that can make up a part of a toolchain must
receive a tool identifier.
These new identifiers can be used to retrieve information about the
toolchain in a more standardized fashion.
For example, logic in a Makefile that should only execute when the C
compiler is GNU GCC can now check the tool identifier for the C compiler
in the relevant toolchain:
ifeq ($($(ARCH)-cc-id),gnu-gcc)
...

CryptoCell-712 and CryptoCell-713 drivers have been deprecated since
TF-A v2.9 and their removal was announced for TF-A v2.10 release.
See [1].
As the release is approaching, this patch deletes these drivers' code as
well as all references to them in the documentation and Arm platforms
code (Nuvoton platform is taken care in a subsequent patch). Associated
build options (ARM_CRYPTOCELL_INTEG and PLAT_CRYPTOCELL_BASE) have also
been removed and thus will have no effect if defined.
This is a breaking change for downstream platforms which use these
drivers.
