2016-03-01Skylake: Support Intel Speed Shift Technology based on configSubrata Banik
Intel Speed Shift Technology is a new mechanism that replaces Legacy P-state. ISST allows OS hints about energy/performance preference. H/W performs the actual P-state control (autonomous) 1. Optimization frequency seclection for low residency workloads, no longer a static knee point. 2. Optimized frequency selection for best energy to performance trade offs. 3. Kick down frequency (from idle) fpr best responsiveness while taking energy consumption init account. Coreboot's responsiblity is to configure MSR 0x1AA ISST_EN bits which will reflect in CPUID.06h:EAX[Bit 7] that driver checkes and enable HWP accordingly.

2015-08-27skylake: only generate ACPI cpu entries onceAaron Durbin
The acpi_fill_ssdt_generator function pointer is evaluated for each device. As there are multiple cpus in the system the acpi_fill_ssdt_generator was being called more than once creating duplicate ACPI entries because there was more than 1 cpu device. Fix this by only generating them once by removing the acpi_fill_ssdt_generator for the cpu devices, but add the generator to the cpu cluster device.

2015-07-29skylake: Update microcode reload in ramstage.Rizwan Qureshi
For Skylake, Microcode is being loaded from FIT, Skylake 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 bootclock and ramstage (MP init). Avoid the microcode reload by checking for PRMRR support.
