There are two classes of SPI controllers on Intel chipsets:
* generic usable SPI controllers
* SPI controller hosting the BIOS flash (fast SPI controller)
While the first class can be used for generic peripheral attachment the
second class mostly controls the BIOS flash and a TPM device (if
enabled). The generic SPI driver is not fully applicable to the fast SPI
controller. In addition, the fast SPI controller reports the reserved
MMIO range used for the BIOS flash mapping so that the OS is aware of
this range.
This patch moves the fast SPI controller of all known SoCs to the
fast SPI driver in common code. In addition, the PCI device for the
fast SPI controller is removed from the function 'spi_soc_devfn_to_bus'
as this is a callback of the generic SPI driver.

All cherry boards (tomato, dojo) share the same SKU ID encoding, in the
sense that a device has NVMe storage if and only if the BIT(1) of SKU ID
is set (otherwise eMMC). Therefore, instead of hard coding the list of
NVMe (PCIe) SKU IDs, we check the BIT(1) to decide whether to initialize
PCIe.
In addition, in preparation for UFS devices coming in the future,
reserve BIT(3) (which is unset for all of current SKUs) for them.

to the MSEG boundry and placing the bios resource list just below
the MSEG where the STM setup functions can find it.

one package. Mainboards can specify which platform type they are using
the `INTEL_LYNXPOINT_LP` Kconfig option. There are so many differences
between Trad and ULT/ULX that it's not worth doing runtime detection.
The CPUIDs are different for Trad and ULT/ULX platforms, and so are the
µcode updates. So, including Trad µcode updates in a coreboot image for
an ULT/ULX mainboard makes no sense, and vice versa.

Add VRM DPTC limit registers. These are required when throttling the SOC
for low/no battery mode to prevent the SOC from overwhelming the
charger.
b/245942343 is tracking passing these additional fields to the FSP and
having the FSP configure them.

Update acpigen_write_alib_dptc() to support "low/no battery mode",
which throttles the SOC when there is no battery connected or the
battery charge is critically low.
This is in preparation for enabling this functionality for Mendocino.

There are platforms equipped with AMD SoC where I2C3 controller
connected to TPM device is shared between X86 and PSP. In order to
handle this, PSP acts as an I2C-arbitrator, where x86 (kernel) sends
acquire and release requests to be accepted by PSP.
Introduce new CONFIG for Mendocino SoCs similar to what we have for
Cezanne.

ELAN6918 Power Sequencing seems not perfectly matching
with the previous platforms and setting GPP_C06 to high prior
to the power sequencing is actually makes it work.
Ideally Power Sequencing should be as below for ELAN6918 (in ACPI)
`POWER enabled -> RESET deasserted -> Report EN enabled`
But below sequence is only working currently:
`Report EN enabled (ramstage) -> POWER enabled (ACPI) -> RESET
deasserted (ACPI)`
