dc667980f8 soc/intel/skylake: Do not let FSP set the subsystem IDs
The subsystem ID registers are read/write-once. Writes by coreboot will
not take effect if FSP sets them.

Note that FSP sets one device ID for the SA devices and another for PCH
devices. coreboot will copy individual vendor and device IDs if
subsystem is not provided.

6c2568f4f5 drivers/spi: Add BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES config
Added new config BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES to accomodate
older x86 platforms that don't allow writing to SPI flash when early
stages are running XIP from flash.  If
BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES is not selected,
BOOT_DEVICE_SPI_FLASH_RW_NOMMAP_EARLY will get auto-selected if
BOOT_DEVICE_SPI_FLASH_RW_NOMMAP=y.  This allows for current platforms
that write to flash in the earlier stages, assuming that they have
that capability.

77cc3267fc soc/intel: Refactor do_global_reset() function
List of changes:
1. Rename do_global_reset() to force_global_reset()
2. Make force_global_reset() function static
3. Implement force_global_reset() into common/reset.c to avoid
dedicated SoC implementation
4. Remove redundant force_global_reset() implementation from
dedicated SoC
5. Make direct call to global_reset() from cse_lite.c
7. Drop CONFIG_HAVE_CF9_RESET_PREPARE Kconfig from APL SoC due
to common reset (soc/intel/common/reset.c) code migration
8. Remove unused function send_global_reset() from SKL me.c due
to common reset code migration
9. Delete heci.c from APL SoC as unused

get_prmrr_size does not return the actual PRMRR size but a valid PRMRR
size with repect to the users choice in Kconfig. Thus, rename it from
`get_prmrr_size` to `get_valid_prmrr_size` to avoid confusion about what
it does.

Also fix the broken comment in cpulib.h.

30c5d21891 soc/intel/skylake: acpi: drop HWP's dependency on EIST
Enhanced Intel SpeedStep Technology (EIST) and Intel Speed Shift
Technology (ISST) - also know as HWP - are two independent mechanisms
for controlling voltage and frequency based on performance hints.

When HWP is enabled, it overrides the software-based EIST. It does not
depend on EIST, though, but can be enabled on its own.

Break up that currently existing dependency in ACPI generation code.

It was tested that HWP can be enabled and gets used by the Linux pstate
cpufreq driver. With HWP disabled, the frequency does not decrease, even
not in powersave mode. After enabling HWP the frequency changed in
relation to the current workload. (Test device: Acer ES1-572)

c1d227d312 soc/intel/common/cpu: Update COS mask calculation for NEM enhanced mode
Update the COS mask calculation to accomodate the RW data as per SoC
configuration. Currently only one way is allocated for RW data and
configured for non-eviction. For earlier platform this served fine,
and could accomodate a RW data up to 256Kb. Starting TGL and JSL, the
DCACHE_RAM_SIZE is configured for 512Kb, which cannot be mapped to a
single way. Hence update the number of ways to be configured for non-
eviction as per total LLC size.

The total LLC size/ number of ways gives the way size. DCACHE_RAM_SIZE/
way size gives the number of ways that need to be configured for non-
eviction, instead of harcoding it to 1.

TGL uses MSR IA32_CR_SF_QOS_MASK_1(0x1891) and IA32_CR_SF_QOS_MASK_2(0x1892)
as COS mask selection register and hence needs to be progarmmed accordingly.

Also JSL and TGL platforms the COS mask selection is mapped to bit 32:33
of MSR IA32_PQR_ASSOC(0xC8F) and need to be updated in edx(maps 63:32)
before MSR write instead of eax(maps 31:0). This implementation corrects
that as well.

Fsp configures the USB over-current pin and overrides the according pad
configuration to NF1, regardless of the port being configured as disabled.

Thus, set the OC pin to 0xff ("disabled") in this case to prevent this.

This allows us to skip setting USBx_PORT_EMPTY in the devicetree for
disabled USB ports.

Simplify some if-blocks which are used for the configuration, enablement

This changes the logic of the code, since it configures PegxEnable
before the if-blocks, where x is the number of the PEG device, and the
further configuration of the PEG devices depends on the enablement of
PegxEnable.
