2019-02-21soc/intel/cannonlake: SoC specific microcode update checkRonak Kanabar
For CFL and WHL, Microcode is being loaded from FIT. Both supports the PRMRR/SGX feature. If This is supported the FIT microcode load will set the msr (0x08b) with the Patch id one less than the id in the microcode binary. This results in Microcode getting reloaded again in bootblock and ramstage. Avoid the microcode reload by checking for PRMRR support. CFL and WHL CPU die are based on KBL CPU so we need to have this check, where CNL CPU die is not based on KBL CPU so skip this check for CNL.

2017-09-11cpu/x86/mp_init: remove adjust_cpu_apic_entry()Aaron Durbin
The original purpose of adjust_cpu_apic_entry() was to set up an APIC map. That map was effectively only used for mapping *default* APIC id to CPU number in the SMM handler. The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.
