2017-03-23soc/intel/skylake: Add SGX initializationRobbie Zhang
This patch implements SGX initialization steps in coreboot per Intel SGX BWG rev 2.0.8 for Kaby Lake SoC. If enabled on a Kabylake device, SoC capability and PRM (processor reserved memory) of desired size (needs to be configured through PrmrrSize) are provisioned for later software stack to use SGX (i.e., run SGX enclaves). One issue is still puzzling and needs to be addressed: by calling configure_sgx() in cpu_core_init() which is the per-thread function, SGX is always failing for thread 0 but is successful for other 3 threads. I had to call configure_sgx() again from soc_init_cpus() which is the BSP-only function to make it enable on the BSP. Another pending work is the implementation for the Owner Epoch update which shall be added later. BUG=chrome-os-partner:62438 BRANCH=NONE TEST=Tested on Eve, verified SGX activation is successful on all threads.

2017-02-22soc/intel/skylake: Fix broken suspend-resumeFurquan Shaikh
With recent change (a4b11e5c90: soc/intel/skylake: Perform CPU MP Init before FSP-S Init) to perform CPU MP init before FSP-S init, suspend resume is currently broken for all skylake/kabylake boards. All the skylake/kabylake boards store external stage cache in TSEG, which is relocated post MP-init. Thus, if FSP loading and initialization is done after MP-init, then ramstage is not able to: 1. Save FSP component in external stage cache during normal boot, and 2. Load FSP component from external stage cache during resume In order to fix this, ensure that FSP loading happens separately from FSP initialization. Add fsp_load callback for pre_mp_init which ensures that the required FSP component is loaded/saved from/to external stage cache. BUG=chrome-os-partner:63114 BRANCH=None TEST=Verified that 100 cycles of suspend/resume worked fine on poppy.

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.
