eb3e0985b8 soc/intel/jasperlake: Fix PMC read_resources callback
The `limit` field for the PMC fixed BAR was incorrectly set to the `base
+ size + 1`, where it should be `base + size - 1`, to correctly tell the
allocator the limit.

2. Using MMIO access when GEN_PMCON_A is a memory mapped register.

d9c5b14f1e intelblocks/pcie: Correct mapping between LCAP port and coreboot index
coreboot uses port index which is 0 based for all PCIe root ports.
In case of PCIe remapping logic, coreboot reads LCAP register from PCIe
configuration space which contains port number (mostly 1 based). This
assumption might not be true for all the ports in coreboot.

TBT's LCAP registers are returning port index which are based on 2.
coreboot's PCIe remapping logic returns port index based on index 1.

This patch adds variable to pcie_rp_config to pass lcap_port_base to the
pcie remapping function, so coreboot can map any n-based LCAP encoding
to 0-based indexing scheme.

This patch updates correct lcap_port_base variable for all PCIe root
ports for all SOCs, so that function returns correct 0-based index from
LCAP port number.

34f26b2989 drivers/fsp/fsp2_0: Rework FSP Notify Phase API configs
This patch renames all FSP Notify Phase API configs to primarily remove
"SKIP_"  prefix.

1. SKIP_FSP_NOTIFY_PHASE_AFTER_PCI_ENUM ->
          USE_FSP_NOTIFY_PHASE_POST_PCI_ENUM
2. SKIP_FSP_NOTIFY_PHASE_READY_TO_BOOT ->
          USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
3. SKIP_FSP_NOTIFY_PHASE_END_OF_FIRMWARE ->
          USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE

The idea here is to let SoC selects all required FSP configs to execute
FSP Notify Phase APIs unless SoC deselects those configs to run native
coreboot implementation as part of the `.final` ops.

For now all SoC that uses FSP APIs have selected all required configs
to let FSP to execute Notify Phase APIs.

Note: coreboot native implementation to skip FSP notify phase API (post
pci enumeration) is still WIP.

Additionally, fixed SoC configs inclusion order alphabetically.

This can be tested by checking sysfs in Linux:

Currently, the MMCONF Kconfigs only support the Enhanced Configuration
Access mechanism (ECAM) method for accessing the PCI config address

space to memory.  This patch renames the following configs to
make it clear that these configs are ECAM-specific:

- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH

586b1beb9c soc/intel: drop Kconfig PM_ACPI_TIMER_OPTIONAL
Technically, it's not depending on the hardware but on the software
(OS/payload), if the PM Timer is optional. OSes with ACPI >= 5.0A
support disabling of the PM Timer, when the respective FADT flag is
unset. Thus, drop this guard.

For platforms without hardware PM Timer (Apollo Lake, Gemini Lake) the
Kconfig `USE_PM_ACPI_TIMER` depends on `!NO_PM_ACPI_TIMER`.

As of this change, new platforms must either implement code for
disabling the hardware PM timer or select `NO_PM_ACPI_TIMER` if no such
is present.

02164027b2 cpu/x86: Introduce and use CPU_X86_LAPIC
With using a Kconfig option to add the x86 LAPIC support code to the
build, there's no need for adding the corresponding directory to subdirs
in the CPU/SoC Makefile. Comparing which CPU/SoC Makefiles added
(cpu/)x86/mtrr and (cpu/)x86/lapic before this and the corresponding
MTRR code selection patch and having verified that all platforms
added the MTRR code on that patch shows that soc/example/min86 and
soc/intel/quark are the only platforms that don't end up selecting the
LAPIC code. So for now the default value of CPU_X86_LAPIC is chosen as y
which gets overridden to n in the Kconfig of the two SoCs mentioned
above.

2d4986c168 cpu,soc/x86: always include cpu/x86/mtrr on x86 CPUs/SoCs
All x86-based CPUs and SoCs in the coreboot tree end up including the
Makefile in cpu/x86/mtrr, so include this directly in the Makefile in
cpu/x86 to add it for all x86 CPUs/SoCs. In the unlikely case that a new
x86 CPU/SoC will be added, a CPU_X86_MTRR Kconfig option that is
selected be default could be added and the new CPU/SoC without MTRR
support can override this option that then will be used in the Makefile
to guard adding the Makefile from the cpu/x86/mtrr sub-directory.

In cpu/intel all models except model 2065X and 206AX are selcted by a
socket and rely on the socket's Makefile.inc to add x86/mtrr to the
subdirs, so those models don't add x86/mtrr themselves. The Intel
Broadwell SoC selects CPU_INTEL_HASWELL and which added x86/mtrr to the
subdirs. The Intel Xeon SP SoC directory contains two sub-folders for
different versions or generations which both add x86/mtrr to the subdirs
in their Makefiles.

4dd7d11965 cpu/x86/mp_init: move printing of failure message into mp_init_with_smm
Each CPU/SoC checks the return value of the mp_init_with_smm and prints
the same error message if it wasn't successful, so move this check and
printk to mp_init_with_smm. For this the original mp_init_with_smm
function gets renamed to do_mp_init_with_smm and a new mp_init_with_smm
function is created which then calls do_mp_init_with_smm, prints the
error if it didn't return CB_SUCCESS and passes the return value of
do_mp_init_with_smm to its caller.

Since no CPU/SoC code handles a mp_init_with_smm failure apart from
printing a message, also add a comment at the mp_init_with_smm call
sites that the code might want to handle a failure.
