This patch fixes incorrect setting for DEVICE1_SIZE
for FVP platforms with more than 8 PEs.
The current value of 0x200000 supports only 8 PEs
and causes exception for FVP platforms with the greater
number of PEs, e.g. FVP_Base_Cortex_A65AEx8 with 16 PEs
in one cluster.

This patch removes re-definition of the following FVP build
options from plat\arm\board\fvp\fvp_def.h:
'FVP_CLUSTER_COUNT'
'FVP_MAX_CPUS_PER_CLUSTER'
'FVP_MAX_PE_PER_CPU'
which are set in platform.mk.
This fixes a potential problem when a build option set in
platform.mk file can be re-defined in fvp_def.h header file
used by other build component with a different makefile which
does not set this option.

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: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("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.

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.

FVPs that model DynamIQ configuration implements all CPUs in a single
cluster. I.e., such models have a single cluster with more than 4 CPUs.
This differs from existing default build configuration for FVP where up
to 4 CPUs are assumed per cluster.
To allow building for DynamIQ configuration, promote the macro
FVP_MAX_CPUS_PER_CLUSTER as a build option to have it set from the build
command line. The value of the build option defaults to 4.

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.

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.

This patch adds support to select CCN driver for FVP during build.
A new build option `FVP_INTERCONNECT_DRIVER` is added to allow
selection between the CCI and CCN driver. Currently only the CCN-502
variant is supported on FVP.
The common ARM CCN platform helper file now verifies the cluster
count declared by platform is equal to the number of root node
masters exported by the ARM Standard platform.

This patch adds support for non-volatile counter authentication to
the Authentication Module. This method consists of matching the
counter values provided in the certificates with the ones stored
in the platform. If the value from the certificate is lower than
the platform, the boot process is aborted. This mechanism protects
the system against rollback.
The TBBR CoT has been updated to include this method as part of the
authentication process. Two counters are used: one for the trusted
world images and another for the non trusted world images.
** NEW PLATFORM APIs (mandatory when TBB is enabled) **
int plat_get_nv_ctr(void *cookie, unsigned int *nv_ctr);
This API returns the non-volatile counter value stored
in the platform. The cookie in the first argument may be
used to select the counter in case the platform provides
more than one (i.e. TBSA compliant platforms must provide
trusted and non-trusted counters). This cookie is specified
in the CoT.
int plat_set_nv_ctr(void *cookie, unsigned int nv_ctr);
This API sets a new counter value. The cookie may be
used to select the counter to be updated.
An implementation of these new APIs for ARM platforms is also
provided. The values are obtained from the Trusted Non-Volatile
Counters peripheral. The cookie is used to pass the extension OID.
This OID may be interpreted by the platform to know which counter
must return. On Juno, The trusted and non-trusted counter values
have been tied to 31 and 223, respectively, and cannot be modified.
** IMPORTANT **
THIS PATCH BREAKS THE BUILD WHEN TRUSTED_BOARD_BOOT IS ENABLED. THE
NEW PLATFORM APIs INTRODUCED IN THIS PATCH MUST BE IMPLEMENTED IN
ORDER TO SUCCESSFULLY BUILD TF.

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.

This patch fixes several issues with the SP804 delay timer on FVP:
* By default, the SP804 dual timer on FVP runs at 32 KHz. In order
to run the timer at 35 MHz (as specified in the FVP user manual)
the Overwrite bit in the SP810 control register must be set.
* The CLKMULT and CLKDIV definitions are mixed up:
delta(us) = delta(ticks) * T(us) = delta(ticks) / f(MHz)
From the delay function:
delta_us = (delta * ops->clk_mult) / ops->clk_div;
Matching both expressions:
1 / f(MHz) = ops->clk_mult / ops->clk_div
And consequently:
f(MHz) = ops->clk_div / ops->clk_mult
Which, for a 35 MHz timer, translates to:
ops->clk_div = 35
ops->clk_mult = 1
* The comment in the delay timer header file has been corrected:
The ratio of the multiplier and the divider is the clock period
in microseconds, not the frequency.

This patch does the following reorganization to psci power management (PM)
handler setup for ARM standard platform ports :
1. The mailbox programming required during `plat_setup_psci_ops()` is identical
for all ARM platforms. Hence the implementation of this API is now moved
to the common `arm_pm.c` file. Each ARM platform now must define the
PLAT_ARM_TRUSTED_MAILBOX_BASE macro, which in current platforms is the same
as ARM_SHARED_RAM_BASE.
2. The PSCI PM handler callback structure, `plat_psci_ops`, must now be
exported via `plat_arm_psci_pm_ops`. This allows the common implementation
of `plat_setup_psci_ops()` to return a platform specific `plat_psci_ops`.
In the case of CSS platforms, a default weak implementation of the same is
provided in `css_pm.c` which can be overridden by each CSS platform.
3. For CSS platforms, the PSCI PM handlers defined in `css_pm.c` are now
made library functions and a new header file `css_pm.h` is added to export
these generic PM handlers. This allows the platform to reuse the
adequate CSS PM handlers and redefine others which need to be customized
when overriding the default `plat_arm_psci_pm_ops` in `css_pm.c`.

Since there is a unique warm reset entry point, the FVP and Juno
port can use a single mailbox instead of maintaining one per core.
The mailbox gets programmed only once when plat_setup_psci_ops()
is invoked during PSCI initialization. This means mailbox is not
zeroed out during wakeup.

This patch extends the platform port by adding an API that returns
either the Root of Trust public key (ROTPK) or its hash. This is
usually stored in ROM or eFUSE memory. The ROTPK returned must be
encoded in DER format according to the following ASN.1 structure:
SubjectPublicKeyInfo ::= SEQUENCE {
algorithm AlgorithmIdentifier,
subjectPublicKey BIT STRING
}
In case the platform returns a hash of the key:
DigestInfo ::= SEQUENCE {
digestAlgorithm AlgorithmIdentifier,
keyDigest OCTET STRING
}
An implementation for ARM development platforms is provided in this
patch. When TBB is enabled, the ROTPK hash location must be specified
using the build option 'ARM_ROTPK_LOCATION'. Available options are:
- 'regs' : return the ROTPK hash stored in the Trusted
root-key storage registers.
- 'devel_rsa' : return a ROTPK hash embedded in the BL1 and
BL2 binaries. This hash has been obtained from the development
RSA public key located in 'plat/arm/board/common/rotpk'.
On FVP, the number of MMU tables has been increased to map and
access the ROTPK registers.
A new file 'board_common.mk' has been added to improve code sharing
in the ARM develelopment platforms.

Add SP804 delay timer support to the FVP BSP.
This commit simply provides the 3 constants needed by the SP804
delay timer driver and calls sp804_timer_init() in
bl2_platform_setup(). The BSP does not currently use the delay
timer functions.
Note that the FVP SP804 is a normal world accessible peripheral
and should not be used by the secure world after transition
to the normal world.
