The project has been renamed from "Arm Trusted Firmware (ATF)" to "Trusted Firmware-A (TF-A)" long ago. A few references to the old project name that still remained in various places have now been removed. This change doesn't affect any platform files. Any "ATF" references inside platform files, still remain. Change-Id: Id97895faa5b1845e851d4d50f5750de7a55bf99e Signed-off-by: John Tsichritzis <john.tsichritzis@arm.com>
