287 Say Y if you need to force the assumption that CPEI can be re-targetted to

289 Tiger4 systems are capable of re-directing CPEI to any CPU other than BSP.
290 This option it useful to enable this feature on older BIOS's as well.
291 You can also enable this by using boot command line option force_cpei=1.
