Simon Glass	45b5a37836	x86: Add multi-processor init ... Most modern x86 CPUs include more than one CPU core. The OS normally requires that these 'Application Processors' (APs) be brought up by the boot loader. Add the required support to U-Boot to init additional APs.

Simon Glass	c72f74e278	x86: ivybridge: Update microcode early in boot ... At present the normal update (which happens much later) does not work. This seems to have something to do with the 'no eviction' mode in the CAR, or at least moving the microcode update after that causes it not to work. For now, do an update early on so that it definitely works. Also refuse to continue unless the microcode update check (later in boot) is successful.
