The `toc_entry` and `image` data structures had a cyclic

functions to link them via the UUID.

This change highlights the intent of the code better and makes it more
flexible for future enhancements.

Instead of always calling the top level usage function when an
error is detected, call the command-specific usage function.

For example running `fiptool create` will produce the same output
as `fiptool help create`.  This is more convenient for the user
when they make a mistake.

This feature allows one to quickly verify that the expected
image is contained in the FIP without extracting the image and
running sha256sum(1) on it.

The sha256 digest is only shown when the verbose flag is used.

This change requires libssl-dev to be installed in order to build
Trusted Firmware. Previously, libssl-dev was optionally needed only
to support Trusted Board Boot configurations.

fiptool provides a more consistent and intuitive interface compared to
the fip_create program.  It serves as a better base to build on more
features in the future.

fiptool supports various subcommands.  Below are the currently
supported subcommands:

1) info   - List the images contained in a FIP file.
2) create - Create a new FIP file with the given images.
3) update - Update an existing FIP with the given images.
4) unpack - Extract a selected set or all the images from a FIP file.
5) remove - Remove images from a FIP file.  This is a new command that
   was not present in fip_create.

To create a new FIP file, replace "fip_create" with "fiptool create".

To update a FIP file, replace "fip_create" with "fiptool update".

To dump the contents of a FIP file, replace "fip_create --dump" with
"fiptool info".

A compatibility script that emulates the basic functionality of
fip_create is provided.  Existing scripts might or might not work with
the compatibility script.  Users are strongly encouraged to migrate to
fiptool.

With the introduction of commit `96103d5a`, the Certificate
Generation tool is not able to generate FWU certificate and
while doing so it does segmentation fault.

This happens because it is now required to pass non-volatile
counter values to the `cert_create` tool from the command line
for creating the trusted firmware certificates.

But in case of creating FWU certificate these counter values are not
being passed to the tool and as a consequence the `cert_create` tool
try to use the NULL argument and errors out with Segmentation fault.

This patch fixes this issue by providing a check before using the
command line argument passed in the case of `EXT_TYPE_NVCOUNTER`
certificate extension.

This patch adds support for image unpacking to the FIP packaging
tool. Command line option '-u,--unpack' may be used to unpack the
contents of an existing FIP file into the working directory. The
tool uses default hardcoded filenames for the unpacked images. If
the files already exist, they can be overwritten by specifying the
option '-f,--force'.

In some build environments executable programs have a specific file
extension.  The value of BIN_EXT is appended to the relevant tool file
names to allow for this.
The value of BIN_EXT is set, where appropriate, by the build environment
specific make helper (to .exe for Windows build environments).

.gitignore is updated to hide the new (.exe) files.

Some build environments do not support symbolic links. This patch
removes the symlinks previously used to build fip_create and instead
copies the relevant header files.
The original motivation for using symlinks was to avoid Trusted Firmware
library headers conflicting with headers in the compiler standard
include path. Copying the header files instead has the same effect.

Like other build artefacts, the copied files are listed in .gitignore.

The distclean targets have also been updated to remove the copies.

Add make helper files to select the appropriate settings for the build

The Trusted Firmware Makefile and supporting tool Makefiles are updated

As an initial stage of making Trusted Firmware build environment more
portable, we remove most uses of the $(shell ) function and replace them
with more portable make function based solutions.

Note that the setting of BUILD_STRING still uses $(shell ) since it's
not possible to reimplement this as a make function. Avoiding invocation
of this on incompatible host platforms will be implemented separately.

This patch adds non-volatile counter support to the Certificate
Generation tool. The TBBR Chain of Trust definition in the tool
has been extended to include the counters as certificate extensions.
The counter values can be specified in the command line.

The following default counter values are specified in the build
system:

  * Trusted FW Non-Volatile counter = 0
  * Non-Trusted FW Non-Volatile counter = 0

These values can be overridden by the platform at build time.

This patch introduces the following improvements:

  * Global variables in fip_create.c declared static.
  * Flags to signal the requested actions (do_dump, do_pack) made
    global.
  * The ToC is printed at the end of the main funcion, after the FIP
    has been created/updated, not in the parse_cmdline() function.
  * Short format added to the command line options (-d,--dump;
    -h,--help).
  * Help message updated.

Change-Id: I5f08273c76f1de45fe597e290bee4b60aa404df9

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).

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

This patch replaces all references to the SCP Firmware (BL0, BL30,
BL3-0, bl30) with the image terminology detailed in the TF wiki
(https://github.com/ARM-software/arm-trusted-firmware/wiki):

    BL0          -->  SCP_BL1
    BL30, BL3-0  -->  SCP_BL2
    bl30         -->  scp_bl2

This change affects code, documentation, build system, tools and
platform ports that load SCP firmware. ARM plaforms have been
updated to the new porting API.

IMPORTANT: build option to specify the SCP FW image has changed:

    BL30 --> SCP_BL2

IMPORTANT: This patch breaks compatibility for platforms that use BL2
to load SCP firmware. Affected platforms must be updated as follows:

    BL30_IMAGE_ID --> SCP_BL2_IMAGE_ID
    BL30_BASE --> SCP_BL2_BASE
    bl2_plat_get_bl30_meminfo() --> bl2_plat_get_scp_bl2_meminfo()

Firmware Update (FWU) introduces a new set of images called
SCP_BL2U, BL2U and NS_BL2U, which can be packed in a FWU FIP file.

This patch introduces new UUIDs for the Firmware Update images
and extends the 'fip'create' tool so that these new images can be
packed in a FIP file.

Change-Id: I7c60211b4f3cc265411efb131e6d3c624768f522

Firmware Update requires an X509v3 certificate which contains
hashes for SCP_BL2U, BL2U and NS_BL2U images as extensions.

This patch extends the Chain of Trust definition in the
'cert_create' tool to include the Firmware Update certificate
and the required extensions (including command line options).
A new field in the extension structure will be used to indicate
that the extension is optional. In the case of an image hash
extension, this field will tell the tool that the hash should
be included in the certificate, but filled with zeros.

Change-Id: I1f77a66b018826b71745910771f38d9cf6050388

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.

Change-Id: I282b0b01cb9add557b26bddc238a28253ce05e44

The certificate generation tool currently checks if all command
line options required to create all certificates in the CoT have
been specified. This prevents using the tool to create individual
certificates when the whole CoT is not required.

This patch improves the checking function so only those options
required by the certificates specified in the command line are
verified.

Change-Id: I2c426a8e2e2dec85b15f2d98fd4ba949c1aed385

This patch reworks the certificate generation tool to follow a data

Some Linux distributions include an OpenSSL library which has been
built without ECDSA support. Trying to build the certificate
generation tool on those distributions will result in a build error.

This patch fixes that issue by including ECDSA support only if
OpenSSL has been built with ECDSA. In that case, the OpenSSL
configuration file does not define the OPENSSL_NO_EC macro. The tool
will build successfully, although the resulting binary will not
support ECDSA keys.

Change-Id: I4627d1abd19eef7ad3251997d8218599187eb902

This patch extends the 'cert_create' tool to support ECDSA keys
to sign the certificates. The '--key-alg' command line option
can be used to specify the key algorithm when invoking the tool.
Available options are:

    * 'rsa': create RSA-2048 keys (default option)
    * 'ecdsa': create ECDSA-SECP256R1 keys

The TF Makefile has been updated to allow the platform to specify
the key algorithm by declaring the 'KEY_ALG' variable in the
platform makefile.

The behaviour regarding key management has changed. After applying
this patch, the tool will try first to open the keys from disk. If
one key does not exist or no key is specified, and the command line
option to create keys has been specified, new keys will be created.
Otherwise an error will be generated and the tool will exit. This
way, the user may specify certain keys while the tool will create
the remaining ones. This feature is useful for testing purposes
and CI infrastructures.

The OpenSSL directory may be specified using the build option
'OPENSSL_DIR' when building the certificate generation tool.
Default is '/usr'.

The cert_create tool calculates the hash of each BL image and includes
it as an ASN.1 OCTET STRING in the corresponding certificate extension.
Without additional information, the firmware running on the platform
has to know in advance the algorithm used to generate the hash.

This patch modifies the cert_create tool so the certificate extensions
that include an image hash are generated according to the following
ASN.1 structure:

    DigestInfo ::= SEQUENCE {
        digestAlgorithm  AlgorithmIdentifier,
        digest           OCTET STRING
    }

    AlgorithmIdentifier ::=  SEQUENCE  {
        algorithm        OBJECT IDENTIFIER,
        parameters       ANY DEFINED BY algorithm OPTIONAL
    }

The PolarSSL module has been updated to extract the image hash
from the certificate extension according to this structure.

Update the top level makefile to allow platform ports to exist in
subdirectories at any level instead of one level under `plat/`. The
makefile recursively searches for all files called `platform.mk` in
all subdirectories of `plat/`. The directory containing
`platform.mk` is the platform name. Platform names must be unique
across the codebase.

Replace usage of HELP_PLATFORMS in the Makefile with PLATFORMS since
these are both used to report the same information back to the user.

Update the TSP and cert_create tool makefiles in a similar way
to support a deeper platform port directory structure.

Also add PLAT_<plat_name> as a define passed through the top level
makefile to the source files, to allow build time variation in common
platform code.

This patch extends the FIP tool to include the certificates
generated by the 'cert_create' tool.

If GENERATE_COT build option is enabled, the Makefile adds the
certificates as dependencies to create the FIP file. Thus, make

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.

If one of the files passed to fip_create on the command line doesn't
exist, it will print an error message but produce an incomplete
fip.bin file and report success. This behaviour could potentially
hide errors made in the command line arguments.

This patch addresses the issue by having the tool bail out if one of
the supplied files can't be processed.
