FVP: Support Base FVP RevC

Revision C of the Base FVP has the same memory map as earlier revisions,
but has the following differences:

- Implements CCI550 instead of CCI400,
- Has a single instantiation of SMMUv3,
- CPU MPIDs are shifted left by one level, and has MT bit set in them.

The correct interconnect to program is chosen at run time based on the
FVP revision. Therefore, this patch implements FVP functions for
interconnect programming, rather than depending on ARM generic ones. The
macros used have been renamed to reflect this change.

Additionally, this patch initializes SMMUv3 as part of FVP early
platform setup.

New ARM config flags are introduced for feature queries at run time.

FVP: Add support for multi-threaded CPUs

ARM CPUs with multi-threading implementation has more than one
Processing Element in a single physical CPU. Such an implementation will
reflect the following changes in the MPIDR register:

- The MT bit set;

- Affinity levels pertaining to cluster and CPUs occupy one level
higher than in a single-threaded implementation, and the lowest
affinity level pertains to hardware threads. MPIDR affinity level
fields essentially appear shifted to left than otherwise.

The FVP port henceforth assumes that both properties above to be
concomitant on a given FVP platform.

To accommodate for varied MPIDR formats at run time, this patch
re-implements the FVP platform-specific functions that translates MPIDR
values to a linear indices, along with required validation. The same
treatment is applied for GICv3 MPIDR hashing function as well.

An FVP-specific build option FVP_MAX_PE_PER_CPU is introduced which
specifies the maximum number of threads implemented per CPU. For
backwards compatibility, its value defaults to 1.

cert: move platform_oid.h to include/tools_share for all platforms

Platforms aligned with TBBR are supposed to use their own OIDs, but
defining the same macros with different OIDs does not provide any
value (at least technically).

For easier use of TBBR, this commit allows platforms to reuse the OIDs
obtained by ARM Ltd. This will be useful for non-ARM vendors that
do not need their own extension fields in their certificate files.

The OIDs of ARM Ltd. have been moved to include/tools_share/tbbr_oid.h

Platforms can include <tbbr_oid.h> instead of <platform_oid.h> by
defining USE_TBBR_DEFS as 1. USE_TBBR_DEFS is 0 by default to keep the
backward compatibility.

For clarification, I inserted a blank line between headers from the
include/ directory (#include <...>) and ones from a local directory
(#include "..." ).

Some header files using the ULL() macro were not directly including

script with values using this macro did not see the macro definition
and kept the "ULL(<value>)" call in the preprocessed file, which lead to
link error.

Resolve build errors flagged by GCC 6.2

With GCC 6.2 compiler, more C undefined behaviour is being flagged as
warnings, which result in build errors in ARM TF build.

The specific issue that this patch resolves is the use of (1 << 31),
which is predominantly used in case statements, where 1 is represented
as a signed int. When shifted to msb the behaviour is undefined.

The resolution is to specify 1 as an unsigned int using a convenience
macro ULL(). A duplicate macro MAKE_ULL() is replaced.

ARM platforms: Define common image sizes

Compile option `ARM_BOARD_OPTIMISE_MMAP` has been renamed to
`ARM_BOARD_OPTIMISE_MEM` because it now applies not only to defines
related to the translation tables but to the image size as well.

The defines `PLAT_ARM_MAX_BL1_RW_SIZE`, `PLAT_ARM_MAX_BL2_SIZE` and
`PLAT_ARM_MAX_BL31_SIZE` have been moved to the file board_arm_def.h.
This way, ARM platforms no longer have to set their own values if
`ARM_BOARD_OPTIMISE_MEM=0` and they can specify optimized values
otherwise. The common sizes have been set to the highest values used
for any of the current build configurations.

This is needed because in some build configurations some images are
running out of space. This way there is a common set of values known
to work for all of them and it can be optimized for each particular
platform if needed.

The space reserved for BL2 when `TRUSTED_BOARD_BOOT=0` has been
increased. This is needed because when memory optimisations are
disabled the values for Juno of `PLAT_ARM_MMAP_ENTRIES` and
`MAX_XLAT_TABLES` are higher. If in this situation the code is
compiled in debug mode and with "-O0", the code won't fit.

This patch adds an option to the ARM common platforms to load BL31 in the
TZC secured DRAM instead of the default secure SRAM.

To enable this feature, set `ARM_BL31_IN_DRAM` to 1 in build options.
If TSP is present, then setting this option also sets the TSP location
to DRAM and ignores the `ARM_TSP_RAM_LOCATION` build flag.

To use this feature, BL2 platform code must map in the DRAM used by
BL31. The macro ARM_MAP_BL31_SEC_DRAM is provided for this purpose.
Currently, only the FVP BL2 platform code maps in this DRAM.

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.

ARM platforms: rationalise memory attributes of shared memory

The shared memory region on ARM platforms contains the mailboxes and,
on Juno, the payload area for communication with the SCP. This shared
memory may be configured as normal memory or device memory at build
time by setting the platform flag 'PLAT_ARM_SHARED_RAM_CACHED' (on
Juno, the value of this flag is defined by 'MHU_PAYLOAD_CACHED').
When set as normal memory, the platform port performs the corresponding
cache maintenance operations. From a functional point of view, this is
the equivalent of setting the shared memory as device memory, so there
is no need to maintain both options.

This patch removes the option to specify the shared memory as normal
memory on ARM platforms. Shared memory is always treated as device
memory. Cache maintenance operations are no longer needed and have
been replaced by data memory barriers to guarantee that payload and
MHU are accessed in the right order.

Rework use of interconnect drivers

ARM Trusted Firmware supports 2 different interconnect peripheral
drivers: CCI and CCN. ARM platforms are implemented using either of the
interconnect peripherals.

This patch adds a layer of abstraction to help ARM platform ports to
choose the right interconnect driver and corresponding platform support.
This is as described below:

1. A set of ARM common functions have been implemented to initialise an
interconnect and for entering/exiting a cluster from coherency. These
functions are prefixed as "plat_arm_interconnect_". Weak definitions of
these functions have been provided for each type of driver.

2.`plat_print_interconnect_regs` macro used for printing CCI registers is
moved from a common arm_macros.S to cci_macros.S.

3. The `ARM_CONFIG_HAS_CCI` flag used in `arm_config_flags` structure
is renamed to `ARM_CONFIG_HAS_INTERCONNECT`.

Re-factor definition of some macros on ARM platforms

This patch moves the definition of some macros used only on

It also forces all ARM standard platforms to have distinct

1. `PLAT_ARM_TZC_BASE` and `PLAT_ARM_NSTIMER_FRAME_ID` have been

2. `MHU_BASE` used in CSS platforms is moved from common css_def.h
to platform specific header `platform_def.h` on Juno and
renamed as `PLAT_ARM_MHU_BASE`.
3. To cater for different sizes of BL images, new macros like
`PLAT_ARM_MAX_BL31_SIZE` have been created for each BL image. All
ARM platforms need to define them for each image.
