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.

2017-06-27soc/intel/skylake: storage: Add 2ms delay before exiting D3Duncan Laurie
For the skylake/kabylake generation of PCH there is an ACPI workaround for emmc/sd power state that involves disabling and re-enabling dynamic clock gating after enabling power to the controller, before setting the power state to D0. Under certain conditions we have observed that the controller is not powered and ready by the time the kernel attempts to read the PME control and status register and so the system will hang while attempting to read PCI config register 0x84. To ensure that the controller is ready add a 2ms delay after re-enabling dynamic clock gating and before setting the power state to D0. This issue has been observed on eMMC, but the same workaround exists for the SD card interface so the same delay is added there. BUG=b:35587084 BRANCH=eve TEST=manual stress testing of D0<>D3 transition across many devices shows no hard hang after 2 days.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

DEVTREE_CONST as a replacment for ROMSTAGE_CONST The ROMSTAGE_CONST attribute is used in the source code to mark the devicetree data structures as const in early stages even though it's not just romstage. Therefore, rename the attribute to DEVTREE_CONST as that's the actual usage. The only place where the usage was not devicetree related is console_loglevel, but the same name was used for consistency. Any stage that is not ramstage has the const C attribute applied when DEVTREE_CONST is used.

This patch attempts to finish the separation between CONFIG_VBOOT and CONFIG_CHROMEOS by moving the remaining options and code (including image generation code for things like FWID and GBB flags, which are intrinsic to vboot itself) from src/vendorcode/google/chromeos to src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig options, and clean up menuconfig visibility for them (i.e. some options were visible even though they were tied to the hardware while others were invisible even though it might make sense to change them).

2017-03-28vboot: Assume EC_SOFTWARE_SYNC and VIRTUAL_DEV_SWITCH by defaultJulius Werner
The virtualized developer switch was invented five years ago and has been used on every vboot system ever since. We shouldn't need to specify it again and again for every new board. This patch flips the Kconfig logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the latter for Lumpy which seems to have been omitted incorrectly, and hide it from menuconfig since it's a hardware parameter that shouldn't be configurable.) Since almost all our developer switches are virtual, it doesn't make sense for every board to pass a non-existent or non-functional developer mode switch in the coreboot tables, so let's get rid of that. It's also dangerously confusing for many boards to define a get_developer_mode() function that reads an actual pin (often from a debug header) which will not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set. Therefore, this patch removes all those non-functional instances of that function. In the future, either the board has a physical dev switch and must define it, or it doesn't and must not. In a similar sense (and since I'm touching so many board configs anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC. Instead, it should just be assumed by default whenever a Chrome EC is present in the system. This way, it can also still be overridden by menuconfig.

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.
