Some systems are configured such that multiple CPUs begin running from their reset vector following a system reset. If this occurs then U-Boot will be run on multiple CPUs simultaneously, which causes all sorts of issues as the multiple instances of U-Boot clobber each other. Prevent this from happening by simply hanging with an infinite loop if we run on a CPU whose ID, as determined by GlobalNumber or EBase.CPUNum as appropriate, is non-zero.
