Juan Castillo 159807e2fa cert_create: update help message
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

Juan Castillo ad2c1a9aa7 cert_create: specify command line options in the CoT
This patch introduces a new API that allows to specify command
line options in the Chain of Trust description. These command line
options may be used to specify parameters related to the CoT (i.e.
keys or certificates), instead of keeping a hardcoded list of
options in main.c.

Juan Castillo 55e291a405 TBB: rework cert_create tool to follow a data driven approach
This patch reworks the certificate generation tool to follow a data
driven approach. The user may specify at build time the certificates,
keys and extensions defined in the CoT, register them using the
appropiate macros and the tool will take care of creating the
certificates corresponding to the CoT specified.

Juan Castillo ea4ec3aad5 TBB: use SHA256 to generate the certificate signatures
This patch replaces SHA1 by SHA256 in the 'cert_create' tool, so
certificate signatures are generated according to the NSA Suite B
cryptographic algorithm requirements.

Documentation updated accordingly.

Juan Castillo 6f97162237 TBB: add tool to generate certificates
This patch adds a tool that generates all the necessary elements
to establish the chain of trust (CoT) between the images.

The tool reads the binary images and signing keys and outputs the
corresponding certificates that will be used by the target at run
time to verify the authenticity of the images.

Note: the platform port must provide the file platform_oid.h. This
file will define the OIDs of the x509 extensions that will be added
to the certificates in order to establish the CoT.
