1. Explicitly add LOGICAL to the reset macro name to make it explicit that the values are logical. 2. Reword some of the comments and combine them into single comment instead of scattering the comments throughout. 3. Use c99 struct initializers for the reset mapping array. 4. For the chipset specific values use literals that match the hardware. 5. Use 'U' suffixes on the literals so we don't trip up compiler being over zealous on undefined behavior. 6. Use unsigned and fixed-width types for the reset mapping structure since the code is reliant on matching up with a register definition. 7. Fix formatting that can fit < 80 cols.

2017-07-12soc/intel/skylake: Remove “disable SaGv” in recovery mode flowSubrata Banik
This reverts commit 5535cead (intel/skylake: Disable SaGv in recovery mode). Commit 5535cead disables SaGv in recovery mode to save few seconds booting time as we were doing memory training on every recovery flow. Now we don't need to perform MRC training on every recovery boot due to RECOVERY_MRC_CACHE implementation in place. Hence we don't need to define different SaGv policy between Normal (developer) mode and recovery mode to save few seconds. Using different SaGv parameters between recovery and all other mode has some significent drawbacks over warm reboot cycle. We are seeing a MRC traning hang in eve/soraka/poppy devices with below use case. Step 1: Boot system in developer mode (first time RW_MRC training) Step 2: Set recovery_request=1 (using crossystem) and issue “reboot” from OS Step 3: System will perform recovery mode MRC training and boot to OS (first time RECOVERY_MRC training) Step 4: Issue “reboot” from OS console. Step 5: System wil boot in developer mode (using RW_MRC cache) Step 6: Set recovery_request=1 (using crossystem) and issue “reboot” from OS Step 7: System will pick RECOVERY_MRC_CACHE and will hang during MRC training. This patch fixes issue mentioned above and ensures system boot to OS without any hang if we change mode (dev<->recovery) over warm reset. BUG=b:63515071 BRANCH=none TEST=manual stress testing of dev<->recovery mode over warm boot. No MRC hang with this fix on eve/soraka/poppy devices.

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.

2017-06-09soc/braswell: fix ACPI table by recollecting TOLMHarry Pan
cherry-pick from Chromium, commit 8fbe1e7 On Braswell and Baytrail devices, by userland 'perf top', observed demanding clocks on __vdso_clock_gettime() since chromeos_3.18 kernel; besides, evaluated massive calling of clock_gettime() cost, up to 700 ns in average. It turns out that Linux kernel of map_vdso() first call of remap_pfn_range() does not fall into reserve_pfn_range() due to size parameter, instead it relies on lookup_memtype() and potentially be failed to be identified as eligible RAM resource because the function of pat_pagerange_is_ram() actually walks through root's sibling. Meanwhile, on current BSW (and BYT) firmware implementation makes System RAM resources located on child leaf, combining all of these factors makes the kernel treat the vvar page of vdso as a uncached-minus one leading slow access in result. This patch recollects TOLM accessing; as Aaron recalled some core_msr_script turns off access to TOLM register, he suggests to store tolm to avoid getting back a zero while setting acpi nvs space.
