3e7f006280 drives/spi/spi_flash: add option to not select all drivers
Add a new Kconfig option, SPI_FLASH_DONT_INCLUDE_ALL_DRIVERS,
to make it easier for other parts of the code base to indicate that
all spi flash drivers should not be included.

b6df6b065c soc/intel/{apl,cnl,icl,skl,tgl}: Make above 4GB MMIO resource proper
This patch ensures coreboot is not publishing above 4GB mmio resource
if soc common config "enable_above_4GB_mmio" not enable.

Publishing unnecessary 4GB above MMIO resource with wrong base and size
is causing problem while working with discrete GPU.

Unable to boot with dGPU on IA platform with below error:

9cb88a70f7 src: Conditionally include TEVT
ACPI method TEVT is reported as unused by iASL (20190509) when ChromeEC support is not
enabled. The message is “Method Argument is never used (Arg0)” on Method (TEVT, 1, NotSerialized),
which indicates the TEVT method is empty.

The solution is to only enable the TEVT code in mainboard or SoC when an EC is used that uses
this event. The TEVT code in the EC is only enabled if the mainboard or SoC code implements TEVT.

The TEVT method will be removed from the ASL code when the EC does not support TEVT.

It is a requirement for Firmware to have Firmware Interface Table (FIT),

The microcode update is loaded for all logical processors before reset vector.

FSPT_UPD.MicrocodeRegionBase and FSPT_UPD.MicrocodeRegionLength are
input parameters to TempRamInit API.
If these values are 0, FSP will not attempt to update microcode.

Since Gen-4 all IA-SoC has FIT loading ucode even before cpu reset in place
hence skipping FSP-T loading ucode after CPU reset options.

Also removed unused kconfig CONFIG_CPU_MICROCODE_CBFS_LOC and
CONFIG_CPU_MICROCODE_CBFS_LEN

7736bfc443 soc/intel/sgx: convert SGX and PRMRR devicetree options to Kconfig
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.

68da45479f soc/intel: skl,cnl,icl: rely on TOLUM as cbmem_top returned by FSP
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.

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.
