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.
Fixes ARM-Software/tf-issues#375

Dump platform-defined regs in crash reporting
...
It is up to the platform to implement the new plat_crash_print_regs macro to
report all relevant platform registers helpful for troubleshooting.
plat_crash_print_regs merges or calls previously defined plat_print_gic_regs
and plat_print_interconnect_regs macros for each existing platforms.
NOTE: THIS COMMIT REQUIRES ALL PLATFORMS THAT ENABLE THE `CRASH_REPORTING`
BUILD FLAG TO MIGRATE TO USE THE NEW `plat_crash_print_regs()` MACRO. BY
DEFAULT, `CRASH_REPORTING` IS ENABLED IN DEBUG BUILDS FOR ALL PLATFORMS.

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.

Simplify Firmware Design document
...
The Firmware Design document is meant to provide a general overview
of the Trusted Firmware code. Although it is useful to provide some
guidance around the responsibilities of the platform layer, it should
not provide too much platform specific implementation details. Right
now, some sections are too tied to the implementation on ARM
platforms. This makes the Firmware Design document harder to digest.
This patch simplifies this aspect of the Firmware Design document.
The sections relating the platform initialisations performed by the
different BL stages have been simplified and the extra details about
the ARM platforms implementation have been moved to the Porting Guide
when appropriate.
This patch also provides various documentation fixes and additions
in the Firmware Design and Platform Porting Guide. In particular:
- Update list of SMCs supported by BL1.
- Remove MMU setup from architectural inits, as it is actually
performed by platform code.
- Similarly, move runtime services initialisation, BL2 image
initialization and BL33 execution out of the platform
initialisation paragraph.
- List SError interrupt unmasking as part of BL1 architectural
initialization.
- Mention Trusted Watchdog enabling in BL1 on ARM platforms.
- Fix order of steps in "BL2 image load and execution" section.
- Refresh section about GICv3/GICv2 drivers initialisation on
ARM platforms.

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.

Porting Guide: Clarify identity-mapping requirement
...
The memory translation library in Trusted Firmware supports
non-identity mappings for Physical to Virtual addresses since commit
f984ce84ba. However, the porting guide hasn't been updated
accordingly and still mandates the platform ports to use
identity-mapped page tables for all addresses.
This patch removes this out-dated information from the Porting Guide
and clarifies in which circumstances non-identity mapping may safely
be used.

Disable PL011 UART before configuring it
...
The PL011 TRM (ARM DDI 0183G) specifies that the UART must be
disabled before any of the control registers are programmed. The
PL011 driver included in TF does not disable the UART, so the
initialization in BL2 and BL31 is violating this requirement
(and potentially in BL1 if the UART is enabled after reset).
This patch modifies the initialization function in the PL011
console driver to disable the UART before programming the
control registers.
Register clobber list and documentation updated.
