Follow https://lore.kernel.org/all/48b554aef75d11e6ad2ef7d21f22accb35432112.1683034376.git.michal.simek@amd.com/
for example of proper commit message and subject line.

The patch content actually is easy to read since it is adding
bootph-all property - but we do have a few exceptions. Commit message
should explain the rational of the choices made. For example, you
probably need to use secure_proxy_sa3 to talk with tifs in-order to
boot and that is a pre-ram property and so on..

So, nice refresh in the right direction, but a bit more work to do.
Thanks for handling am69-sk :)..
