2017-07-01soc/intel/skylake: Remove unnecessary P-State and Flex Ratio assignmentBarnali Sarkar
This patch basically does two things - 1) Remove unnecessary setting of flex_ratio to TDP nominal: Factory configured (default) Max Non-TURBO ratio(P1) is already cofigured in MSR_PLATFORM_INFO(0xCE). If this Maximum Non-TURBO Ratio(P1) needs to be modified, it should be done using MSR_FLEX_RATIO (0x194). Here, in this code, the FLEX_RATIO is being modified by the TDP Nominal Ratio, reading the MSR_CONFIG_TDP_NOMINAL(0x648). But this value is actually less than the factory configured Maximum Non TURBO Ratio (P1). So, this code is actually not required. Also, the Bit 12 in PCH Soft Strap Register is already set in descriptor. This Bit implies Processor Boot Max Frequency - 0 = Disable Boot Max Frequency 1 = Enable Boot Max Frequency (Default) This setting determines if the processor will operate at maximum frequency at power-on and boot. Thus this patch will avoid one extra platform warm reset now onwards. 2) Remove wrongly setting Max Frequency in Bootblock phase: In the function set_max_frequency(), the P-State max ratio was set to TDP Nominal ratio if C-TDP was enabled, else it was set to Max Non Trbo ratio. But, when the cpu gets reset, it will operate with the Max-Non Turbo ratio only, which is greater than the TDP Nominal ratio. So, no need to set back the ratio to TDP Nominal which is lower than the currently operating frequency.

2017-06-09soc/intel/skylake: Move update microcode from cbfs to mp_ops callbacksBarnali Sarkar
FIT is already loading microcode before CPU Reset. So, we need not update the microcode again in RO FW in bootblock. But we need to update in RW FW if there is any new ucode version. So, added the update microcode function in get_microcode_info callback before MP Init to make sure BSP is using the microcode from cbfs.

2015-07-29Skylake: Fix microcode reload in bootblock cpu initRizwan Qureshi
If 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 the bootblock cpu init. Avoid the microcode reload by checking for PRMRR support.
