All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers

This patch implements support for adding dynamic configurations for
BL31 (soc_fw_config), BL32 (tos_fw_config) and BL33 (nt_fw_config). The
necessary cert tool support and changes to default chain of trust are made
for these configs.

This patch updates the `fiptool` and `cert_create` for the
`hw_config` and `tb_fw_config` dynamic configuration files.
The necessary UUIDs and OIDs are assigned to these files and
the `cert_create` is updated to generate appropriate hashes
and include them in the "Trusted Boot FW Certificate". The
`fiptool` is updated to allow the configs to be specified
via cmdline and included in the generated FIP.

Since Trusted OS firmware may have extra images, need to
assign new uuid and image id for them.
The TBBR chain of trust has been extended to add support
for the new images within the existing Trusted OS firmware
content certificate.

To make software license auditing simpler, use SPDX[0] license
identifiers instead of duplicating the license text in every file.

This patch applies the TBBR naming convention to the certificates
and the corresponding extensions defined by the CoT:

    * Certificate UUID names
    * Certificate identifier names
    * OID names

Changes apply to:

    * Generic code (variables and defines)
    * The default certificate identifiers provided in the generic
      code
    * Build system
    * ARM platforms port
    * cert_create tool internal definitions
    * fip_create and cert_create tools command line options
    * Documentation

IMPORTANT: this change breaks the compatibility with platforms
that use TBBR. The platform will need to adapt the identifiers
and OIDs to the TBBR naming convention introduced by this patch:

Certificate UUIDs:

    UUID_TRUSTED_BOOT_FIRMWARE_BL2_CERT --> UUID_TRUSTED_BOOT_FW_CERT
    UUID_SCP_FIRMWARE_BL30_KEY_CERT --> UUID_SCP_FW_KEY_CERT

    UUID_EL3_RUNTIME_FIRMWARE_BL31_CERT --> UUID_SOC_FW_CONTENT_CERT
    UUID_SECURE_PAYLOAD_BL32_KEY_CERT --> UUID_TRUSTED_OS_FW_KEY_CERT

    UUID_NON_TRUSTED_FIRMWARE_BL33_KEY_CERT --> UUID_NON_TRUSTED_FW_KEY_CERT

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.

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.
