help
Enable this to support CPU drivers in SPL. These drivers can set
up CPUs and provide information about them such as the model and
name. This can be useful in SPL since setting up the CPUs earlier
may improve boot performance. Enable this option to build the
drivers in drivers/cpu as part of an SPL build.
