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 adds support for ARM Cortex-A35 processor in the CPU
specific framework, as described in the Cortex-A35 TRM (r0p0).

Change-Id: Ief930a0bdf6cd82f6cb1c3b106f591a71c883464

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).

Fixes ARM-software/tf-issues#337

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.

Change-Id: I84d602630a2585e558d927b50dfde4dd2112496f

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.

"However, the rest of this document assumes that you got the

Also, tidied up the grammar in this section.

FWU: Add documentation for Firmware Update feature

This patch adds design documentation for the Firmware Update (FWU)
feature in `firmware-update.md`. It provides an overview of FWU,
describes the BL1 SMC interface, and includes diagrams showing
an example FWU boot flow and the FWU state machine.

This patch also updates the existing TF documents where needed:

*   `porting-guide.md`
*   `user-guide.md`
*   `firmware-design.md`
*   `rt-svc-writers-guide.md`
*   `trusted_board_boot.md`

Introduce the ARM TF reset design document (v2)

Documentation updates for the new GIC drivers

FWU: Pass client cookie to FWU_SMC_UPDATE_DONE

This patch introduces a new document presenting the ARM Trusted
Firmware Reset Design. It shows the reset code flow, lists the
different build options that affect it, in which case to use them
and what their exact effect is.

The section about using BL31 entrypoint as the reset address has
been moved from the general firmware design document to this one.
It's also been improved to explain why the FVP port supports the
RESET_TO_BL31 configuration, even though the reset vector address
can't be programmed dynamically.

This document includes some images, which have been generated using
Dia version 0.97.2. This tool can be obtained from:
https://wiki.gnome.org/Apps/Dia/Download
This patch provides:
 - the image files describing the different reset flow diagrams;
 - the source '.dia' file;
 - a script automating the generation of the images from the '.dia'
   file.
Note that the 2 latter files are not actually needed for the document
and are provided for convenience only, in case the reset images need
to be modified.
