The patch fixes indication of incorrect `prev_sleep_state` on the next
boot after global reset trigger. The existing code misses an important check about `if PCH doesn't set the WAK_STS` while checking power
failure. As a result, every early warm/global reset is considered
as power failure after looking into the PMC MMIO CON-A register
alone (as ignoring the ACPI PM_CTRL.WAK_STS bit).
As per the code comment this code logic is expected to check the power
failure reason if PCH doesn't set the WAK_STS while waking from G3
state.

Without this patch:
Observation: Resuming after a warm reset is considered as

This patch moves `pmc_clear_pmcon_sts` function into common code and
remove SoC specific instances.
Accessing PMC GEN_PMCON_A register differs between different Intel
chipsets. Typically, there are two possible ways to perform GEN_PMCON_A
register programming (like `pmc_clear_pmcon_sts()`) as:
1. Using PCI configuration space when GEN_PMCON_A is a PCI configuration
register.
2. Using MMIO access when GEN_PMCON_A is a memory mapped register.
SoC users to select `SOC_INTEL_MEM_MAPPED_PM_CONFIGURATION` Kconfig to
perform GEN_PMCON_A register programming using PMC MMIO.

Normally for vboot-enabled x86 board, the VBNV region is stored in CMOS
and backed up to flash (RW_NVRAM). However, on the very first boot after
a flash of the full SPI image (so RW_NVRAM is empty), if
RTC_BATTERY_DEAD is set, coreboot persistently requests recovery before
FSP-M finishes (which appears to be the current location that
RTC_BATTERY_DEAD is cleared on this platform). This is because
vbnv_cmos_failed() will still return 1. Therefore, immediately after
reading RTC_BATTERY_DEAD, it is cleared. This prevents an infinite boot
loop when trying to set the recovery mode bit.
Note that this was the behavior for previous generations of Intel PMC
programming as well (see southbridge/intel, soc/skylake, soc/broadwell,
etc).

Commit 2c26108208 moved this function to
pmutil.c for Tiger Lake. Do this to all other platforms for consistency.
For Skylake, __SIMPLE_DEVICE__ preprocessor guards are no longer needed.
With this change, pmc.c is only needed in ramstage. Adjust Makefile.inc
accordingly, and drop ENV_RAMSTAGE guards from Skylake.

This is a copy patch from Tiger Lake SoC code.
The only changes done on top of copy is changing below configs:
1. SOC_INTEL_TIGERLAKE -> SOC_INTEL_TIGERLAKE_COPY
2. SOC_INTEL_JASPERLAKE -> SOC_INTEL_JASPERLAKE_COPY
3. SOC_INTEL_TIGERLAKE_BASE -> SOC_INTEL_TIGERLAKE_BASE_COPY
We started with initial assumption that JSL and TGL can co-exist.
But now we see the SoC code in Tiger Lake is relying on too many
compile-time directives to make two SoCs co-exist. Some of the
differences are listed below:
-> Kconfig: Multiple Kconfig options using
if SOC_INTEL_{TIGERLAKE/JASPERLAKE}
-> GPIO: GPIO communities have their own differences.
This requires conditional checks in gpio.asl, gpio.c, gpio*.h,
pmc.h and gpio.asl
-> PCI IRQs: Set up differently for JSL and TGL
-> PCIe: Number of Root ports differ.
-> eMMC/SD: Only supported on JSL.
-> USB: Number of USB port are different for JSL and TGL.
-> Memory configuration parameters are different for JSL and TGL.
-> FSP parameters for JSL and TGL are different.
The split of JSL and TGL SoC code is planned as below:
1. Copy Tiger Lake SoC code as is, and change SoC Kconfig
to avoid conflicts with current mainboard builds.
2. Clean up TGL code out of copy patch done in step 1.
Make it JSL only code. The SoC config still kept as
SOC_INTEL_JASPERLAKE_COPY.
3. Change JSL SOC Kconfig from SOC_INTEL_JASPERLAKE_COPY to
SOC_INTEL_JASPERLAKE, dedede and jasperlake_rvp boards can
bind to SoC code from soc/intel/jasperlake. This step establishes
Jasper Lake as a separate SoC.
4. Clean up current JSL code from TGL code. This step establishes
Tiger Lake as a separate SoC.
