TBB: add non-volatile counter support
...
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.

Add support to load BL31 in DRAM
...
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`.

Perform security setup separately for each ARM platform

Perform security setup separately for each ARM platform
...
Prior to this patch, it was assumed that on all ARM platforms the bare
minimal security setup required is to program TrustZone protection. This
would always be done by programming the TZC-400 which was assumed to be
present in all ARM platforms. The weak definition of
platform_arm_security_setup() in plat/arm/common/arm_security.c
reflected these assumptions.
In reality, each ARM platform either decides at runtime whether
TrustZone protection needs to be programmed (e.g. FVPs) or performs
some security setup in addition to programming TrustZone protection
(e.g. NIC setup on Juno). As a result, the weak definition of
plat_arm_security_setup() is always overridden.
When a platform needs to program TrustZone protection and implements the
TZC-400 peripheral, it uses the arm_tzc_setup() function to do so. It is
also possible to program TrustZone protection through other peripherals
that include a TrustZone controller e.g. DMC-500. The programmer's
interface is slightly different across these various peripherals.
In order to satisfy the above requirements, this patch makes the
following changes to the way security setup is done on ARM platforms.
1. arm_security.c retains the definition of arm_tzc_setup() and has been
renamed to arm_tzc400.c. This is to reflect the reliance on the
TZC-400 peripheral to perform TrustZone programming. The new file is
not automatically included in all platform ports through
arm_common.mk. Each platform must include it explicitly in a platform
specific makefile if needed.
This approach enables introduction of similar library code to program
TrustZone protection using a different peripheral. This code would be
used by the subset of ARM platforms that implement this peripheral.
2. Due to #1 above, existing platforms which implements the TZC-400 have been
updated to include the necessary files for both BL2, BL2U and BL31
images.

It also forces all ARM standard platforms to have distinct
definitions (even if they are usually the same).
1. `PLAT_ARM_TZC_BASE` and `PLAT_ARM_NSTIMER_FRAME_ID` have been
moved from `css_def.h` to `platform_def.h`.
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.

Rework use of ARM GIC drivers on ARM platforms
...
Suport for ARM GIC v2.0 and v3.0 drivers has been reworked to create three
separate drivers instead of providing a single driver that can work on both
versions of the GIC architecture. These drivers correspond to the following
software use cases:
1. A GICv2 only driver that can run only on ARM GIC v2.0 implementations
e.g. GIC-400
2. A GICv3 only driver that can run only on ARM GIC v3.0 implementations
e.g. GIC-500 in a mode where all interrupt regimes use GICv3 features
3. A deprecated GICv3 driver that operates in legacy mode. This driver can
operate only in the GICv2 mode in the secure world. On a GICv3 system, this
driver allows normal world to run in either GICv3 mode (asymmetric mode)
or in the GICv2 mode. Both modes of operation are deprecated on GICv3
systems.
ARM platforms implement both versions of the GIC architecture. This patch adds a
layer of abstraction to help ARM platform ports chose the right GIC driver and
corresponding platform support. This is as described below:
1. A set of ARM common functions have been introduced to initialise the GIC and
the driver during cold and warm boot. These functions are prefixed as
"plat_arm_gic_". Weak definitions of these functions have been provided for
each type of driver.
2. Each platform includes the sources that implement the right functions
directly into the its makefile. The FVP can be instantiated with different
versions of the GIC architecture. It uses the FVP_USE_GIC_DRIVER build option
to specify which of the three drivers should be included in the build.
3. A list of secure interrupts has to be provided to initialise each of the
three GIC drivers. For GIC v3.0 the interrupt ids have to be further
categorised as Group 0 and Group 1 Secure interrupts. For GIC v2.0, the two
types are merged and treated as Group 0 interrupts.
The two lists of interrupts are exported from the platform_def.h. The lists
are constructed by adding a list of board specific interrupt ids to a list of
ids common to all ARM platforms and Compute sub-systems.
This patch also makes some fields of `arm_config` data structure in FVP redundant
and these unused fields are removed.

Prepare platforms to use refactored ARM GIC drivers
...
This patch adds platform helpers for the new GICv2 and GICv3 drivers in
plat_gicv2.c and plat_gicv3.c. The platforms can include the appropriate
file in their build according to the GIC driver to be used. The existing
plat_gic.c is only meant for the legacy GIC driver.
In the case of ARM platforms, the major changes are as follows:
1. The crash reporting helper macro `arm_print_gic_regs` that prints the GIC CPU
interface register values has been modified to detect the type of CPU
interface being used (System register or memory mappped interface) before
using the right interface to print the registers.
2. The power management helper function that is called after a core is powered
up has been further refactored. This is to highlight that the per-cpu
distributor interface should be initialised only when the core was originally
powered down using the CPU_OFF PSCI API and not when the CPU_SUSPEND PSCI API
was used.
3. In the case of CSS platforms, the system power domain restore helper
`arm_system_pwr_domain_resume()` is now only invoked in the `suspend_finish`
handler as the system power domain is always expected to be initialized when
the `on_finish` handler is invoked.
