2019-11-09arch/x86: Replace some __SMM__ guardsKyösti Mälkki
We generally do not guard source in attempts to reduce the final object sizes, but rely on garbage collection. Most of the __unused attributes inserted here will be removed when remaining __SIMPLE_DEVICE__ guards can be removed.

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.

2019-11-02timestamps: COLLECT_TIMESTAMPS is mostly optionalKyösti Mälkki
It is a user-visible option and enabled by default for ARCH_X86, some consider it as debugging aid only. Therefore platform design should not depend on it. It must remain selected with CHROMEOS and boards are allowed to explicitly select it as well. For siemens/mc_bdx1,mc_aplX boot time will be increased due the use of get_us_since_boot() with COLLECT_TIMESTAMPS=n. When unable to determine if N seconds has elapsed from boot, this turns into a delay of N seconds.

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].

2019-06-04soc/intel/braswell: Use common cpu/intel/car codeArthur Heymans
The code in cpu/intel/car/romstage.c Does most of the things like setting up timestamps, stack guards, entering postcar. A functional difference is that the FSP header is searched for twice instead of passed from the CAR entry to the C code. When using C_ENVIRONMENT_BOOTBLOCK this needs to be done anyway (or a special linker symbol kept across multiple stages is needed, which is likely not worth the speedup).

Enabling flashconsole on these platforms fails to build due to spi.c not being compiled in prior to ramstage. Include in early stages (bootblock/romstage/postcar) as needed to enable flashconsole support. Early inclusion of monotonic_timer.c is needed for Broadwell as well.

2019-05-21soc/intel/fsp1.1: Implement postcar stageArthur Heymans
This moves FSP1.1 to use postcar stage to tear down CAR. On platforms with USE_GENERIC_FSP_CAR_INC the FSP header is found during the postcar stage so there is no need to push to save it in CAR global variables. On FSP1.1 platforms with an open source CAR implementation (Skylake, even though it still runs the FSP-T), the soc/intel/common/blocks/cpu/car/exit_car.S code tears down CAR. This also uses common functions to set up the MTRR to use after CAR is torn down.

2019-05-07intel/fsp1_1: Drop remnants of `pei_data`Nico Huber
`pei_data` was a struct with blob parameters from pre-FSP times. Somehow, it sneaked into upstream FSP1.1 support (probably because early board ports were written for a different blob). When added upstream, its usage was already perverted. It was declared at SoC level but mostly used to pass mainboard data from mainboard code to itself and FSP data from FSP code to itself. Now that no board/ SoC code uses it anymore, we can finally drop it.
