If we need this option, say what the option is, why we need it, and include an example of how to use it in the commit log. Include the option in the subject line, too, e.g., "Add pci=notph option to disable TPH". Or maybe "prevent use of TPH"? "Disable TPH" hints that BIOS might have enabled it, and this option would turn that off. I haven't looked hard enough to know exactly what you intend or whether there's a difference.
