From: Laszlo Ersek <ler...@redhat.com> Add a PCD for defining a hello message that gets printed to the serial port very early in the boot process, regardless of debug masks. This is useful for debugging boot problems (especially in virtual machines) and informs interactive users that the firmware is running.
If a platform doesn't want this feature, it should stick with the default empty string.
