2019-09-03soc/skylake: do not rely on P2SB data to generate DRHDAngel Pons
The P2SB PCI device can be "hidden", which causes all sorts of nightmares and bugs. Moreover, FSP tends to hide it, so finding a good solution to this problem is impossible with FSP into the mix. Since the values for IBDF and HBDF were already hardcoded as FSP parameters, define them as macros and use these values directly to generate the DRHD.

2019-09-02soc/intel/common/timer: Make TSC frequency calculation dynamicallySubrata Banik
tsc_freq_mhz() had a static table of Intel CPU families and crystal clock, but it is possible to calculate the crystal clock speed dynamically, and this is preferred over hardcoded table. On SKL/KBL/CML CPUID.15h.ecx = nominal core crystal clock = 0 Hz hence we had to use static table to calculate crystal clock. Recommendation is to make use of CPUID.16h where crystal clock frequency was not reported by CPUID.15h to calculate the crystal clock.

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].
