2019-12-19arch/x86,soc/intel: Drop RESET_ON_INVALID_RAMSTAGE_CACHEKyösti Mälkki
If stage cache is enabled, we should not allow S3 resume to load firmware from non-volatile memory. This also adds board reset for failing to load postcar from stage cache.

2019-12-14Revert "{northbridge,soc,southbridge}: Don't use both of _ADR and _HID"Nico Huber
This reverts commit 01787608670adec26fcea48173e18395e51c790e. AMD: Dropping the _HID of PCI root bus doesn't work well and people started to notice the breakage. Intel: These platforms have a devicetree switch to choose between PCI and ACPI modes. In the former case we need _ADR, but in the latter _HID as the PCI devices are hidden. The conflicting use of _ADR and _HID still needs to be fixed before we can bump our IASL version.

2019-11-03cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATEKyösti Mälkki
The x86 timers are a bit of a mess. Cases where different stages use different counters and timestamps use different counters from udelays. The original intention was to only flip TSC_CONSTANT_RATE Kconfig to NOT_CONSTANT_TSC_RATE. The name would be incorrect though, those counters do run with a constant rate but we just lack tsc_freq_mhz() implementation for three platforms. Note that for boards with UNKNOWN_TSC_RATE=y, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the platforms. Implementations with LAPIC_MONOTONIC_TIMER typically will not have tsc_freq_mhz() implemented and default to UNKNOWN_TSC_RATE. However, as they don't use TSC for udelay() the slow calibrate_tsc_with_pit() is avoided. Because x86/tsc_delay.tsc was using two different guards and nb/via/vx900 claimed UDELAY_TSC, but pulled UDELAY_IO implementation, we also switch that romstage to use UDELAY_TSC.

2019-10-16intel/broadwell: Implement proper backlight PWM configNico Huber
Port the backlight-PWM handling from Skylake instead of the previously used Haswell version. We use a 200Hz PWM signal for all boards. Which is higher than the previous devicetree value, 183Hz, but that was over- ridden by the VBIOS anyway. 200Hz is still very low, considering LED backlights, but accurate values are unknown at this time. Lynx Point, the PCH for Haswell and Broadwell, is a transition point for the backlight-PWM config. On platforms with a PCH, we have: o Before Lynx Point: The CPU has no PWM pin and sends the PWM duty-cycle setting to the PCH. The PCH can choose to ignore that and use its own setting (BLM_PCH_OVERRIDE_ENABLE). We use the CPU setting on these platforms. o Lynx Point + Haswell: The CPU has an additional PWM pin but can be set up to send its setting to the PCH as before. The PCH can still choose to ignore that. We use the CPU setting with Haswell. o Lynx Point + Broadwell: The CPU can't send its setting to the PCH anymore. BLM_PCH_ OVERRIDE_ENABLE must always be set(!) if the PCH PWM pin is used (it virtually always is). We have to use the PCH setting in this case. o After Lynx Point: Same as with Broadwell, only BLM_PCH_OVERRIDE_ENABLE is implied and the bit not implemented anymore.

2019-08-28intel/haswell,broadwell: Rename EMRR to PRMRRKyösti Mälkki
The MSRs were already named as PRMRR in broadwell, just mismatching with the rest of the code. All later devices use the names PRMRR and UNCORE_PRMRR for these MSRs. Reflect the name change in structures and local variables.

2019-08-20src: Remove variable length arraysJacob Garber
Variable length arrays were a feature added in C99 that allows the length of an array to be determined at runtime. Eg. int sum(size_t n) { int arr[n]; ... } This adds a small amount of runtime overhead, but is also very dangerous, since it allows use of an unlimited amount of stack memory, potentially leading to stack overflow. This is only worsened in coreboot, which often has very little stack space to begin with. Citing concerns like this, all instances of VLA's were recently removed from the Linux kernel. In the immortal words of Linus Torvalds [0], AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and much _slower_ code (and more fragile code), than just using a fixed key size would have done. [...] Anyway, some of these are definitely easy to just fix, and using VLA's is actively bad not just for security worries, but simply because VLA's are a really horribly bad idea in general in the kernel. This patch follows suit and zaps all VLA's in coreboot. Some of the existing VLA's are accidental ones, and all but one can be replaced with small fixed-size buffers. The single tricky exception is in the SPI controller interface, which will require a rewrite of old drivers to remove [1].
