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.

Added a new platform porting function plat_panic_handler, to allow
platforms to handle unexpected error situations. It must be
implemented in assembly as it may be called before the C environment
is initialized. A default implementation is provided, which simply
spins.
Corrected all dead loops in generic code to call this function
instead. This includes the dead loop that occurs at the end of the
call to panic().
All unnecesary wfis from bl32/tsp/aarch64/tsp_exceptions.S have
been removed.

`board_arm_def.h` contains multiple definitions of
`PLAT_ARM_MMAP_ENTRIES` and `MAX_XLAT_TABLES` that are optimised for
memory usage depending upon the chosen build configuration. To ease
maintenance of these constants, this patch replaces their multiple
definitions with a single set of definitions that will work on all ARM
platforms.
Platforms can override the defaults with optimal values by enabling the
`ARM_BOARD_OPTIMISE_MMAP` build option. An example has been provided in
the Juno ADP port.
Additionally, `PLAT_ARM_MMAP_ENTRIES` is increased by one to accomodate
future 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.

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.

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`.
Change-Id: I02f31184fbf79b784175892d5ce1161b65a0066c
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.

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

Each platform is expected to export its PART_NUMBER separately.
Additionally, it also adds juno part number.

This patch moves the definition of some macros used only on
ARM platforms from common headers to platform specific headers.
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.

for clarity.
Upstream platforms currently do not use this argument so no

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.

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.

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 adds watchdog support on ARM platforms (FVP and Juno).
A secure instance of SP805 is used as Trusted Watchdog. It is
entirely managed in BL1, being enabled in the early platform setup
hook and disabled in the exit hook. By default, the watchdog is
enabled in every build (even when TBB is disabled).
A new ARM platform specific build option `ARM_DISABLE_TRUSTED_WDOG`
has been introduced to allow the user to disable the watchdog at
build time. This feature may be used for testing or debugging
purposes.
Specific error handlers for Juno and FVP are also provided in this
patch. These handlers will be called after an image load or
authentication error. On FVP, the Table of Contents (ToC) in the FIP
is erased. On Juno, the corresponding error code is stored in the
V2M Non-Volatile flags register. In both cases, the CPU spins until
a watchdog reset is generated after 256 seconds (as specified in
the TBBR document).

Normally, in the FVP port, secondary CPUs are immediately powered

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.

This patch adds the capability to power down at system power domain level
on Juno via the PSCI SYSTEM SUSPEND API. The CSS power management helpers
are modified to add support for power management operations at system
power domain level. A new helper for populating `get_sys_suspend_power_state`
handler in plat_psci_ops is defined. On entering the system suspend state,
the SCP powers down the SYSTOP power domain on the SoC and puts the memory
into retention mode. On wakeup from the power down, the system components
on the CSS will be reinitialized by the platform layer and the PSCI client
is responsible for restoring the context of these system components.
According to PSCI Specification, interrupts targeted to cores in PSCI CPU
SUSPEND should be able to resume it. On Juno, when the system power domain
is suspended, the GIC is also powered down. The SCP resumes the final core
to be suspend when an external wake-up event is received. But the other
cores cannot be woken up by a targeted interrupt, because GIC doesn't
forward these interrupts to the SCP. Due to this hardware limitation,
we down-grade PSCI CPU SUSPEND requests targeted to the system power domain
level to cluster power domain level in `juno_validate_power_state()`
and the CSS default `plat_arm_psci_ops` is overridden in juno_pm.c.
A system power domain resume helper `arm_system_pwr_domain_resume()` is
defined for ARM standard platforms which resumes/re-initializes the
system components on wakeup from system suspend. The security setup also
needs to be done on resume from system suspend, which means
`plat_arm_security_setup()` must now be included in the BL3-1 image in
addition to previous BL images if system suspend need to be supported.

PLAT_NUM_PWR_DOMAINS macros are removed from arm_def.h and are made platform
specific. In addition, the `arm_power_domain_tree_desc[]` and
`arm_pm_idle_states[]` are modified to support the system power domain
at level 2. With this patch, even though the power management operations
involving the system power domain will not return any error, the platform
layer will silently ignore any operations to the power domain. The actual
power management support for the system power domain will be added later.

* Replace the strong definition of `plat_arm_calc_core_pos` in
css_helpers.S with a utility function `css_calc_core_pos_swap_cluster`

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`.

Currently, on ARM platforms(ex. Juno) non-secure access to specific
peripheral regions, config registers which are inside and outside CSS
is done in the soc_css_security_setup(). This patch separates the CSS
security setup from the SOC security setup in the css_security_setup().
The CSS security setup involves programming of the internal NIC to
provide access to regions inside the CSS. This is needed only in
Juno, hence Juno implements it in its board files as css_init_nic400().

The mailbox gets programmed only once when plat_setup_psci_ops()
