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.

RT1011 is a smart amplifier. It needs to know speaker related parameters
including speaker resistor value and temperature when the calibration is
done in order to run Dynamic Speaker Management (DSM) algorithm on chip.
The purpose of DSM is to protect speaker when the volume is large.
The calibration data of speaker is stored in VPD in factory.
This driver is needed to read data from VPD and write to ACPI _DSD when
config CHROMEOS_DSM_CALIB is turned on.
Kernel rt1011 codec driver will read these device properties to set up
codec accordingly on boot.
The reason to prepare these parameters in coreboot is because kernel
codec driver expects to read per-device parameters directly from device
properties. Another benefit is that other OS can also take these
parameters through ACPI _DSD table and take benefit of DSM on RT1011.
The kernel driver device properties of RT1011 are documented at
linux/Documentation/devicetree/bindings/sound/rt1011.txt
It is currently in ASoC maintainer's tree at
https://kernel.googlesource.com/pub/scm/linux/kernel/git/broonie/sound/+/for-next/
and hopefully should be merged to mainline kernel in the next merge window.
BUG=b:140397934
BRANCH=none

Auto-discoverable PCI devices do not require field .enable_dev

by the use of PCI vendor and device ID fields.
The name given for the chip_operations struct must match the
pathname the way it is present in the devicetree.cb files. If
there was no match, util/sconfig would currently choose to
use the empty weak declaration it creates in static.c file.

Added a framework to search VPD in romstage before memory is
avilable. vpd_cbmem.c and vpd_premem.c are added for
code specific for premem environment and for environment that
cbmem can be used.
Since global variable is forbidden in romstage. A CAR_GLOBAL
variable is defined in vpd.c. This variable holds VPD binary
blobs' base address and size from memory mapped flash.
The overall flow is:
* The CAR variable g_vpd_blob is initialized if it was not,
either at romstage (before FSP-M execution in case of FSP UPD
customization), or at ramstage.
* At ramstage, during CBMEM_INIT, the VPD binary blob contents
are copied into CBMEM.
* At vpd_find() which may be called at romstage or at ramstage,
it sets storage for a local struct vpd_blob variable.
* The variable gets contents duplicated from g_vpd_blob, if
vpd_find() is called at romstage.
* The variable gets contents obtained from CBMEM, if vpd_find()
is called at ramstage.
Added a call vpd_get_bool(). Given a key/value pair in VPD
binary blob, and name of a bool type variable, set the variable
value if there is a match.
Several checks are in place:
* The key/value length needs to be correct.
* The key name needs to match.
* THe value is either '1' or '0'.
Test Plan:
* Build an OCP MonoLake coreboot image, flash and run.

This provides stack guards with checking and common
entry into postcar.
The code in cpu/intel/car/romstage.c is candidate
for becoming architectural so function prototype
is moved to <arch/romstage.h>.

This Device ID is specific to CML, since it is obtained by reading ISH
configuration RO register.
In order to export ISH to kernel PCI device tree, this number must be
included in list of devices supported.

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].
