Boyan Karatotev 572635cdf1 chore(commitlint): tell editors commit line lengths are 72 characters
The repository obeys an 100 character soft limit for source lines.
However, commit messages generally have lines shorter than 72 characters
to make gerrit print them without wrapping.

Annoyingly, the editorconfig can't express this and the 100 character
limit applies to commit messages, requiring manual formatting. Luckily,
when writing commit messages the file `.git/COMMIT_EDITMSG` is open. So
we can set its line length to be 72 characters.

Trusted Firmware-A
==================

Trusted Firmware-A (TF-A) is a reference implementation of secure world software
for `Arm A-Profile architectures`_ (Armv8-A and Armv7-A), including an Exception
Level 3 (EL3) `Secure Monitor`_. It provides a suitable starting point for
productization of secure world boot and runtime firmware, in either the AArch32
or AArch64 execution states.

TF-A implements Arm interface standards, including:

-  `Power State Coordination Interface (PSCI)`_
-  `Trusted Board Boot Requirements CLIENT (TBBR-CLIENT)`_
-  `SMC Calling Convention`_
-  `System Control and Management Interface (SCMI)`_
-  `Software Delegated Exception Interface (SDEI)`_

The code is designed to be portable and reusable across hardware platforms and
software models that are based on the Armv8-A and Armv7-A architectures.

In collaboration with interested parties, we will continue to enhance TF-A
with reference implementations of Arm standards to benefit developers working
with Armv7-A and Armv8-A TrustZone technology.

Users are encouraged to do their own security validation, including penetration
testing, on any secure world code derived from TF-A.
