0d6ddf8da7 cpu/x86/tsc: Flip and rename TSC_CONSTANT_RATE to UNKNOWN_TSC_RATE
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.

de09679c13 timestamps: COLLECT_TIMESTAMPS is mostly optional
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.

40f893e9f3 soc/intel: common,skl,cnl,icl: drop reserved mmio memory size calculation
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.

b4383fc759 soc/skl/vr_config: set Iccmax_gt depends on CPU/GT
According to the DC Current Specifications [1], the current limit for
the graphical VR domain (Iccmax_gt) isn't same for different Kaby Lake S
CPUs. This value should depend on the iGPU model and processor TDP:

  +---------------------+-----+------------+
  |       Segment       | TDP | Icc_max GT |
  +---------------------+-----+------------+
  | Dual Core GT2/GT1   | 35W |            |
  | Dual Core GT2       | 51W |    48 A    |
  | Dual Core GT1       | 54W |            |
  +---------------------+-----+------------+
  | Quad Core GT2       | 35W |    35 A    |
  +---------------------+-----+------------+
  | Quad Core GT2       | 65W |    45 A    |
  | Quad Core GT2 K-SKU | 91W |            |
  +---------------------+-----+------------+

This patch adds the remaining Iccmax_gt current limit values from the
documentation [1].

The filename chip.h has a special purpose with the generation
of static devicetree, where the configuration structure name matches
the path to the chip.h file. For example, soc/intel/skylake/chip.h
defines struct soc_intel_skylake_config.

The renamed file did not follow this convention and the structure it
defines would conflict with one defined soc/intel/common/chip.h if such
is ever added.

ef879a8f30 soc/skylake: do not rely on P2SB data to generate DRHD
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.

9172b6920c src: Remove variable length arrays
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].

There are no provisions in Kconfig to degrade from

As a security measure CBMEM_STAGE_CACHE default is changed to
disabled. AGESA platforms without TSEG will experience slower

bcdb893778 soc/intel/{broad,cannon,sky}: Fix possible out-of-bounds reads
There will be a possible out of bounds array access if
power_limit_1_time == ARRAY_SIZE(power_limit_time_sec_to_msr), so
prevent that in the index check. This issue was fixed for other cpus in
commit 5cfef13f8d (cpu/intel: Fix out-of-bounds read due to off-by-one
in condition). Based on the discussion for that commit, also remove the
magic constant 28 in favour of the index of the last array element.

b28658995d soc/intel: Guard remaining SA_DEV_ROOT definition
Prevent implicit cast to pointers.

The compiler doesn't warn about the conversion from
integer to pointer without a cast, because SA_DEV_ROOT
is literally '0' and there seems to be an exception
for that conversion.
