Saving cbmem_top across stages is not needed anymore so EBDA should not be used. The guard to cbmem_top_chipset implementation was inappropriate.

2019-11-04soc/intel/sgx: convert SGX and PRMRR devicetree options to KconfigMichael Niewöhner
The devicetree is not made for user-choosable options, thus introduce Kconfig options for both SGX and the corresponding PRMRR size. The PRMRR size Kconfig has been implemented as a maximum value. At runtime the final PRMRR size gets selected by checking the supported values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest to the chosen one. When "Maximum" is chosen, the highest possibly value from the MSR gets used. When a too strict limit is set, coreboot will die, printing an error message.

2019-11-04soc/intel: skl,cnl,icl: rely on TOLUM as cbmem_top returned by FSPMichael Niewöhner
Instead of doing our own calculations, rely on TOLUM returned by FSP for cbmem_top. This (hopefully) saves us from making mistakes in weird calculations of offsets and alignments. Further this makes it easier to implement e.g. SGX PRMRR size selection via Kconfig as we do not have to make any assumptions about alignments but can simply pass (valid) values to FSP.

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.

Remove the calculation of the Reserved Intel MMIO Memory size from systemagent and memmap, since it is not needed. The size is used in SA to calculate the space between cbmem_top and TSEG without DPR and Chipset Reserved Memory. Since this will always be equal to 0, the reservation will be skipped and TSEG, DPR and Chipset Reserved Memory will get reserved alltogether. By reading the code and pratical testing we figured out that: - TSEG - DPR - reserved - top_of_memory == 0 - TSEG - DPR - reserved == top_of_memory This means the whole block will never reserve anything because it is always 0. Hence the code can be removed for simplification.

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].
