+ 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.
