Add optional PSCI STAT residency & count functions
...
This patch adds following optional PSCI STAT functions:
- PSCI_STAT_RESIDENCY: This call returns the amount of time spent
in power_state in microseconds, by the node represented by the
`target_cpu` and the highest level of `power_state`.
- PSCI_STAT_COUNT: This call returns the number of times a
`power_state` has been used by the node represented by the
`target_cpu` and the highest power level of `power_state`.
These APIs provides residency statistics for power states that has
been used by the platform. They are implemented according to v1.0
of the PSCI specification.
By default this optional feature is disabled in the PSCI
implementation. To enable it, set the boolean flag
`ENABLE_PSCI_STAT` to 1. This also sets `ENABLE_PMF` to 1.

Add Performance Measurement Framework(PMF)
...
This patch adds Performance Measurement Framework(PMF) in the
ARM Trusted Firmware. PMF is implemented as a library and the
SMC interface is provided through ARM SiP service.
The PMF provides capturing, storing, dumping and retrieving the
time-stamps, by enabling the development of services by different
providers, that can be easily integrated into ARM Trusted Firmware.
The PMF capture and retrieval APIs can also do appropriate cache
maintenance operations to the timestamp memory when the caller
indicates so.
`pmf_main.c` consists of core functions that implement service
registration, initialization, storing, dumping and retrieving
the time-stamp.
`pmf_smc.c` consists SMC handling for registered PMF services.
`pmf.h` consists of the macros that can be used by the PMF service
providers to register service and declare time-stamp functions.
`pmf_helpers.h` consists of internal macros that are used by `pmf.h`
By default this feature is disabled in the ARM trusted firmware.
To enable it set the boolean flag `ENABLE_PMF` to 1.
NOTE: The caller is responsible for specifying the appropriate cache
maintenance flags and for acquiring/releasing appropriate locks
before/after capturing/retrieving the time-stamps.

Allow dynamic overriding of ROTPK verification
...
A production ROM with TBB enabled must have the ability to boot test software
before a real ROTPK is deployed (e.g. manufacturing mode). Previously the
function plat_get_rotpk_info() must return a valid ROTPK for TBB to succeed.
This patch adds an additional bit `ROTPK_NOT_DEPLOYED` in the output `flags`
parameter from plat_get_rotpk_info(). If this bit is set, then the ROTPK
in certificate is used without verifying against the platform value.
Fixes ARM-software/tf-issues#381

Build option to include AArch32 registers in cpu context
...
The system registers that are saved and restored in CPU context include
AArch32 systems registers like SPSR_ABT, SPSR_UND, SPSR_IRQ, SPSR_FIQ,
DACR32_EL2, IFSR32_EL2 and FPEXC32_EL2. Accessing these registers on an
AArch64-only (i.e. on hardware that does not implement AArch32, or at
least not at EL1 and higher ELs) platform leads to an exception. This patch
introduces the build option `CTX_INCLUDE_AARCH32_REGS` to specify whether to
include these AArch32 systems registers in the cpu context or not. By default
this build option is set to 1 to ensure compatibility. AArch64-only platforms
must set it to 0. A runtime check is added in BL1 and BL31 cold boot path to
verify this.
Fixes ARM-software/tf-issues#386

As of commit e1ea9290bb, if the attributes of an inner memory region
are different than the outer region, new page tables are generated
regardless of how "restrictive" they are. This patch removes an
out-dated comment still referring to the old priority system based
on which attributes were more restrictive.

Fill exception vectors with zero bytes
...
The documentation of the GNU assembler specifies the following about
the .align assembler directive:
"the padding bytes are normally zero. However, on some systems, if
the section is marked as containing code and the fill value is
omitted, the space is filled with no-op instructions."
(see https://sourceware.org/binutils/docs/as/Align.html)
When building Trusted Firmware, the AArch64 GNU assembler uses a
mix of zero bytes and no-op instructions as the padding bytes to
align exception vectors.
This patch mandates to use zero bytes to be stored in the padding
bytes in the exception vectors. In the AArch64 instruction set, no
valid instruction encodes as zero so this effectively inserts
illegal instructions. Should this code end up being executed for
any reason, it would crash immediately. This gives us an extra
protection against misbehaving code at no extra cost.

This patch introduces some assembler macros to simplify the
declaration of the exception vectors. It abstracts the section
the exception code is put into as well as the alignments
constraints mandated by the ARMv8 architecture. For all TF images,
the exception code has been updated to make use of these macros.
This patch also updates some invalid comments in the exception
vector code.

PSCI: Add pwr_domain_pwr_down_wfi() hook in plat_psci_ops
...
This patch adds a new optional platform hook `pwr_domain_pwr_down_wfi()` in
the plat_psci_ops structure. This hook allows the platform to perform platform
specific actions including the wfi invocation to enter powerdown. This hook
is invoked by both psci_do_cpu_off() and psci_cpu_suspend_start() functions.
The porting-guide.md is also updated for the same.
This patch also modifies the `psci_power_down_wfi()` function to invoke
`plat_panic_handler` incase of panic instead of the busy while loop.

PERIPHERAL_ID 0 register in the CCN driver. This ID allows to distinguish
the variant of CCN present on the system and possibly enable dynamic
configuration of the IP based on the variant. Also added an assert in
`ccn_master_to_rn_id_map()` to ensure that the master map bitfield provided
by the platform is within the expected interface id.

IO: support block device type

FIP is accessed as memory-mapped type. eMMC is block device type.
In order to support FIP based on eMMC, add the new io_block layer.
io_block always access eMMC device as block size. And it'll only
copy the required data into buffer in io_block driver. So preparing
an temporary buffer is required.
When use io_block device, MAX_IO_BLOCK_DEVICES should be declared
in platform_def.h. It's used to support multiple block devices.
