The debug prints used to debug translation table setup in xlat_tables.c
used the `printf()` standard library function instead of the stack
optimized `tf_printf()` API. DEBUG_XLAT_TABLE option was used to enable
debug logs within xlat_tables.c and it configured a much larger stack
size for the platform in case it was enabled. This patch modifies these
debug prints within xlat_tables.c to use tf_printf() and modifies the format
specifiers to be compatible with tf_printf(). The debug prints are now enabled
if the VERBOSE prints are enabled in Trusted Firmware via LOG_LEVEL build
option.

The much larger stack size definition when DEBUG_XLAT_TABLE is defined
is no longer required and the platform ports are modified to remove this
stack size definition.

cdefs.h: Use __deprecated__ instead of deprecated

ARM plat: add build option to unlock access to non-secure timer

Use the form with underscores to define the '__deprecated' macro to avoid
collisions with potentially defined macros, as suggested in gcc docs
(https://gcc.gnu.org/onlinedocs/gcc/Attribute-Syntax.html#Attribute-Syntax

).

Currently, Trusted Firmware on ARM platforms unlocks access to the
timer frame registers that will be used by the Non-Secure world. This
unlock operation should be done by the Non-Secure software itself,
instead of relying on secure firmware settings.

This patch adds a new ARM specific build option 'ARM_CONFIG_CNTACR'
to unlock access to the timer frame by setting the corresponding
bits in the CNTACR<N> register. The frame id <N> is defined by
'PLAT_ARM_NSTIMER_FRAME_ID'. Default value is true (unlock timer
access).

Documentation updated accordingly.

Fixes ARM-software/tf-issues#170

FVP: Compile ARM Cortex-A72 CPU support in

Add 'MAX_MMAP_REGIONS' and 'ADDR_SPACE_SIZE' to the Porting Guide

cert_create: update help message

Rearrange fields in TF data structures to reduce padding

Add support for ARM Cortex-A35 processor

Various documentation fixes

This patch adds a brief description of 'MAX_MMAP_REGIONS' and
'ADDR_SPACE_SIZE' to the Porting Guide. These fields must be defined
by the platform in order to use the translation table library.

Change-Id: Ida366458fe2bc01979091a014dc38da0fae5991e

This patch rearranges fields of the `image_desc_t` & `auth_img_desc_t`
data structures to reduce padding between the fields and thereby
save memory.

NOTE: Platform ports which anonymously initialize these structures
should be aware of the rearrangement and do the required
modification.

This patch changes the anonymous initialization of `rt_svc_desc_t` structure
by the `DECLARE_RT_SVC` macro to designated initialization. This makes the
code more robust and less sensitive to potential changes to the
`rt_svc_desc_t` structure.

This patch fixes a couple of issues in the "CPU specific operations
framework" section in the Firmware Design document.

 * Fix broken link to the CPU Specific Build Macros document.

 * Fix the path to the cortex_a53.S file.

 * Fix power levels terminology.

The help message printed by the cert_create tool using the command
line option -h (or --help) does not correctly list all the available
command line options.

This patch reworks the print_help() function to print the help
messages in a data driven approach. For each command line option
registered, an optional help message can be specified, which will
be printed by print_help().

Help messages for the TBBR options (certificates, keys and images)
are also provided.

Fix a small bug in the short options string passed to getopt_long:
the ':' was missing in the '-a' option (this option must take an
argument).

Apply TBBR naming convention to the fip_create options

Always build with '-pedantic'

Add ret to return from console_uninit() function

The fip_create tool specifies images in the command line using the
ARM TF naming convention (--bl2, --bl31, etc), while the cert_create
tool uses the TBBR convention (--tb-fw, --soc-fw, etc). This double
convention is confusing and should be aligned.

This patch updates the fip_create command line options to follow the
TBBR naming convention. Usage examples in the User Guide have been
also updated.

NOTE: users that build the FIP by calling the fip_create tool directly
from the command line must update the command line options in their
scripts. Users that build the FIP by invoking the main ARM TF Makefile
should not notice any difference.

By default ARM TF is built with the '-pedantic' compiler flag, which
helps detecting violations of the C standard. However, the mbed TLS
library and its associated authentication module in TF used to fail
building with this compiler flag. As a workaround, the mbed TLS
authentication module makefile used to set the 'DISABLE_PEDANTIC'
TF build flag.

The compiler errors flagged by '-pedantic' in the mbed TLS library
have been fixed between versions 1.3.9 and 2.2.0 and the library now
properly builds with this compiler flag.

This patch fixes the remaining compiler errors in the mbed TLS
authentication module in TF and unsets the 'DISABLE_PEDANTIC' TF
build flag. This means that TF is now always built with '-pedantic'.

In particular, this patch:

 * Removes the final semi-colon in REGISTER_COT() macro.

   This semi-colon was causing the following error message:

   drivers/auth/tbbr/tbbr_cot.c:544:23: error: ISO C does not allow
   extra ';' outside of a function [-Werror=pedantic]

   This has been fixed both in the mbed TLS authentication module
   as well as in the certificate generation tool. Note that the latter
   code didn't need fixing since it is not built with '-pedantic' but
   the change has been propagated for consistency.

   Also fixed the REGISTER_KEYS() and REGISTER_EXTENSIONS() macros,
   which were suffering from the same issue.

 * Fixes a pointer type.

   It was causing the following error message:

   drivers/auth/mbedtls/mbedtls_crypto.c: In function 'verify_hash':
   drivers/auth/mbedtls/mbedtls_crypto.c:177:42: error: pointer of
   type 'void *' used in arithmetic [-Werror=pointer-arith]

The 'ret' was missing in console_uninit() implementation, so the
program doesn't return from console_uninit(). Instead, it keeps
executing the following instructions which is not expected.
