Add support for a minimal secure interrupt service in sp_min for
the AArch32 implementation. Hard code that only FIQs are handled.
Introduce bolean build directive SP_MIN_WITH_SECURE_FIQ to enable
FIQ handling from SP_MIN.
Configure SCR[FIQ] and SCR[FW] from generic code for both cold and
warm boots to handle FIQ in secure state from monitor.
Since SP_MIN architecture, FIQ are always trapped when system executes
in non secure state. Hence discard relay of the secure/non-secure
state in the FIQ handler.

The current build system and driver requires the CCI product to be
specified at build time. The device constraints can be determined at run
time from its ID registers, obviating the need for specifying them
ahead.
This patch adds changes to identify and validate CCI at run time. Some
global variables are renamed to be in line with the rest of the code
base.
The build option ARM_CCI_PRODUCT_ID is now removed, and user guide is
updated.

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 an early suspend handler, that executes with
SMP and data cache enabled. This handler allows platforms to
perform any early actions during the CPU suspend entry sequence.
This handler is optional and platforms can choose to implement it
depending on their needs. The `pwr_domain_suspend` handler still
exists and platforms can keep on using it without any side effects.

At the moment, various parts of the Trusted Firmware code assume
that the granule size used is 4 KB. For example, the linker scripts
enforce 4 KB alignment restrictions on some sections.
However, the ARMv8-A architecture allows 16 KB and 64 KB granule
sizes as well. Some other parts of the TF code, particularly the
architectural code and definitions, have been implemented with
this in mind and cater for all 3 cases.
This discrepancy creates some confusion as to what is effectively
supported in TF. This patch adds some code comments and clarification
in the documentation to make this limitation clearer.

This patch makes the necessary changes to enable ARM platform to
successfully integrate CryptoCell during Trusted Board Boot. The
changes are as follows:
* A new build option `ARM_CRYPTOCELL_INTEG` is introduced to select
the CryptoCell crypto driver for Trusted Board boot.
* The TrustZone filter settings for Non Secure DRAM is modified
to allow CryptoCell to read this memory. This is required to
authenticate BL33 which is loaded into the Non Secure DDR.
* The CSS platforms are modified to use coherent stacks in BL1 and BL2
when CryptoCell crypto is selected. This is because CryptoCell makes
use of DMA to transfer data and the CryptoCell SBROM library allocates
buffers on the stack during signature/hash verification.

This patch updates the el3_arch_init_common macro so that it fully
initialises essential control registers rather then relying on hardware
to set the reset values.
The context management functions are also updated to fully initialise
the appropriate control registers when initialising the non-secure and
secure context structures and when preparing to leave EL3 for a lower
EL.
This gives better alignement with the ARM ARM which states that software
must initialise RES0 and RES1 fields with 0 / 1.
This patch also corrects the following typos:
"NASCR definitions" -> "NSACR definitions"

Added checks to FWU_SMC_IMAGE_COPY to prevent loading data into a
memory region where another image data is already loaded.
Without this check, if two images are configured to be loaded in
overlapping memory regions, one of them can be loaded and
authenticated and the copy function is still able to load data from
the second image on top of the first one. Since the first image is
still in authenticated state, it can be executed, which could lead to
the execution of unauthenticated arbitrary code of the second image.

ARM GIC-600 IP complies with ARM GICv3 architecture, but among others,
implements a power control register in the Redistributor frame. This
register must be programmed to mark the frame as powered on, before
accessing other registers in the frame. Rest of initialization sequence
remains the same.
The driver provides APIs for Redistributor power management, and
overrides those in the generic GICv3 driver. The driver data is shared
between generic GICv3 driver and that of GIC-600.
For FVP platform, the GIC-600 driver is chosen when FVP_USE_GIC_DRIVER

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 "..." ).

The behaviour of assert() now depends on the value of the new optional
platform define `PLAT_LOG_LEVEL_ASSERT`. This defaults to `LOG_LEVEL` if
not defined by the platform.
- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_VERBOSE`, it prints the file
name, line and asserted expression.
- If `PLAT_LOG_LEVEL_ASSERT` >= `LOG_LEVEL_INFO`, it prints the file
name and line.
- If not, it doesn't print anything.
Note the old behaviour was to print the function name whereas now it
prints the file name. This reduces memory usage because the file name is
shared between all assert calls in a given file. Also, the default
behaviour in debug builds is to no longer print the asserted expression,
greatly reducing the string usage.
For FVP debug builds this change saves approximately:

In AArch64, privileged exception levels control the execution state
(a.k.a. register width) of the immediate lower Exception Level; i.e.
whether the lower exception level executes in AArch64 or AArch32 state.
For an exception level to have its execution state changed at run time,
it must request the change by raising a synchronous exception to the
higher exception level.
This patch implements and adds such a provision to the ARM SiP service,
by which an immediate lower exception level can request to switch its
execution state. The execution state is switched if the request is:
- raised from non-secure world;
- raised on the primary CPU, before any secondaries are brought online
with CPU_ON PSCI call;
- raised from an exception level immediately below EL3: EL2, if
implemented; otherwise NS EL1.
If successful, the SMC doesn't return to the caller, but to the entry
point supplied with the call. Otherwise, the caller will observe the SMC
returning with STATE_SW_E_DENIED code. If ARM Trusted Firmware is built
for AArch32, the feature is not supported, and the call will always
fail.
For the ARM SiP service:
- Add SMC function IDs for both AArch32 and AArch64;
- Increment the SiP service minor version to 2;
- Adjust the number of supported SiP service calls.
Add documentation for ARM SiP service.
