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.

Move mem-protect definitions to board specific files
...
Having these definitions in board_arm_def.h forces to
all the arm platforms to use the same definition for
PLAT_ARM_MEM_PROT_ADDR.
This macro also enables the mem-protect mechanism,
which means that all the arm platform has enabled
mem-protect and they cannot get rid of it.

Allow multi cluster topology definitions for ARM platforms
...
The common topology description helper funtions and macros for
ARM Standard platforms assumed a dual cluster system. This is not
flexible enough to scale to multi cluster platforms. This patch does
the following changes for more flexibility in defining topology:
1. The `plat_get_power_domain_tree_desc()` definition is moved from
`arm_topology.c` to platform specific files, that is `fvp_topology.c`
and `juno_topology.c`. Similarly the common definition of the porting
macro `PLATFORM_CORE_COUNT` in `arm_def.h` is moved to platform
specific `platform_def.h` header.
2. The ARM common layer porting macros which were dual cluster specific
are now removed and a new macro PLAT_ARM_CLUSTER_COUNT is introduced
which must be defined by each ARM standard platform.
3. A new mandatory ARM common layer porting API
`plat_arm_get_cluster_core_count()` is introduced to enable the common
implementation of `arm_check_mpidr()` to validate MPIDR.
4. For the FVP platforms, a new build option `FVP_NUM_CLUSTERS` has been
introduced which allows the user to specify the cluster count to be
used to build the topology tree within Trusted Firmare. This enables
Trusted Firmware to be built for multi cluster FVP models.

Add support for SSC_VERSION register on CSS platforms
...
Each ARM Compute Subsystem based platform implements a System Security
Control (SSC) Registers Unit. The SSC_VERSION register inside it carries
information to identify the platform. This enables ARM Trusted Firmware
to compile in support for multiple ARM platforms and choose one at
runtime. This patch adds macros to enable access to this register.
Each platform is expected to export its PART_NUMBER separately.
Additionally, it also adds juno part number.

Juno: Rework platform reset handler
...
This patch splits the Juno reset handler in 4 distinct pieces:
- Detection of the board revision;
- Juno R0 specific handler;
- Juno R1 specific handler;
- Juno R2 specific handler.
Depending on the board revision, the appropriate handler is called.
This makes the code easier to understand and maintain.
This patch is mainly cosmetic. The only functional change introduced
is that the Juno platform reset handler will now spin infinitely if
the board revision is not recognised. Previously, it would have
assumed that it was running on Juno R1 in this case.

Configure all secure interrupts on ARM platforms
...
ARM TF configures all interrupts as non-secure except those which
are present in irq_sec_array. This patch updates the irq_sec_array
with the missing secure interrupts for ARM platforms.
It also updates the documentation to be inline with the latest
implementation.
Fixes ARM-software/tf-issues#312
