A pointer to soc_acpi_write_tables gets assigned to the
write_acpi_tables element of the device_operations struct, so make sure
that the function has the expected function signature which in this case
means using unsigned long as type for both the 'current' parameter and
the return value.

Since the romstage code is very similar between all AMD non-CAR SoCs,
factor out a common romstage implementation. All SoCs that select
SOC_AMD_COMMON_BLOCK_PM_CHIPSET_STATE_SAVE call fill_chipset_state, so
this Kconfig option can be used to determine whether to make that call.
In the FSP case, amd_fsp_early_init gets called, while in the case of an
implementation that doesn't rely on an FSP to do the initialization,
cbmem_initialize_empty gets called to set up CBMEM which otherwise would
be done inside the FSP driver code. Since only some SoCs call
fch_disable_legacy_dma_io again in romstage right after
amd_fsp_early_init, introduce the new
SOC_AMD_COMMON_ROMSTAGE_LEGACY_DMA_FIXUP Kconfig option, so that the
SoCs can specify if this call is needed or not.

The acpi_fill_madt implementation from the Genoa PoC also works for the
other AMD SoCs that select SOC_AMD_COMMON_BLOCK_DATA_FABRIC_DOMAIN, so
factor out this function to the common AMD ACPI code and change those
other SoCs to use the new common functionality instead of having their
own implementations.
The old code on the single-domain SoCs used the GNB_IO_APIC_ADDR base
address to create the MADT entry for the additional IOAPIC in the root
complex. The new code iterates over all domains and looks for a resource
with the IOMMU_IOAPIC_IDX index in each domain and if it finds it, it
creates an MADT entry for that IOAPIC. This resource is created earlier
in the boot process when the non-PCI resources are read from the IOHC
registers and reported to the allocator.
TEST=The resulting MADT doesn't change on Mandolin

Commit e728766f4596 ("soc/amd/mendocino: Do not load MP2 Firmware when
in RO") added logic to ensure that the MP2 disable soft fuse bit was set
for the RO section, but failed to check if the bit was already set
otherwise (as it is for non-ChromeOS builds). This caused the bit to
appear twice in the PSP_RO_SOFTFUSE_BITS string, and when the string
was converted to a series of numeric values and added together, bit
(n+1) ended up being set instead of bit n.
To mitigate this, use the makefile sort() function to ensure the
PSP_[RO_]SOFTFUSE_BITS string does not contain any duplicates before
the bitmask is calculated. Apply this to all AMD SoC makefiles where
the softfuse bits are added.
TEST=build/boot google/skyrim (frostflow). Use a verbose build (V=1)
to verify that the correct soft fuse value is passed to amdfwtool for
RO and RW_A/B for both ChromeOS and non-ChromeOS builds.

Move all security patch level (SPL) related Kconfig options to the
common AMD PSP Kconfig file. Commit 4ab1db82bb30 ("soc/amd: rework SPL
file override and SPL fusing handling") already reworked the SPL
handling, but missed that another Kconfig option
SOC_AMD_COMMON_BLOCK_PSP_FUSE_SPL controlled if the PSP mailbox command
to update the SPL fuses was sent by the code that got added to the build
when PERFORM_SPL_FUSING was selected.
To make things less unexpected, rename PERFORM_SPL_FUSING to
SOC_AMD_COMMON_BLOCK_PSP_SPL since it actually controls if the SPL
support code is added to the build and also rename
SOC_AMD_COMMON_BLOCK_PSP_FUSE_SPL to PERFORM_SPL_FUSING. This changes
what PERFORM_SPL_FUSING will do from including the code that could do
the fusing if another option is set to being the option that controls if
the fusing mailbox command will be set. All SoCs that support SPL now
select SOC_AMD_COMMON_BLOCK_PSP_SPL in their Kconfig, which won't burn
any SPL fuses.
The logic in the Skyrim mainboard Kconfig file is reworked to select
PERFORM_SPL_FUSING for all boards on which the SPL fuses should be
updated; on Guybrush PERFORM_SPL_FUSING default is changed to y for all
variants. The option to include the code that checks the SPL fusing
conditions and allows sending the command to update the SPL fuses if the
corresponding Kconfig is set doesn't need to be added on the mainboard
level, since it's already selected at the SoC level.

The SPL_TABLE_FILE and SPL_RW_AB_TABLE_FILE Kconfig options provide a
way to override the default SPL file configured in the SoC's fw.cfg file
by passing the '--spl-table' parameter to amdfwtool which will then use
the override instead of the SPL file from the fw.cfg file. When
SPL*_TABLE_FILE is an empty string, the corresponding add_opt_prefix
call in the makefile will result in no '--spl-table' parameter being
passed to amdfwtool, so it'll use the default SPL file from fw.cfg. In
order to not pass an SPL override by default, remove the default from
the SPL_TABLE_FILE in the SoC's Kconfig. The SoC default pointed to the
same SPL file as in fw.cfg file anyway. Now only when a mainboard sets
this option to point to a file, that file will be used as an override.
This override is used to include a special SPL file needed for the
verstage on PSP case on the Chromebooks. Since SPL_TABLE_FILE is an
empty string by default, neither the SPL_TABLE_FILE Kconfig option nor
it being evaluated in the Makefile need to be guarded by HAVE_SPL_FILE,
so remove the dependency in the Kconfig and the ifeq in the Makefile.
Before this patch, the HAVE_SPL_FILE option controlled two things that
shouldn't be controlled by the same Kconfig option: Only when
HAVE_SPL_FILE was set to y, the SPL_TABLE_FILE override was taken into
account, and it also controls if spl_fuse.c got added to the build which
when added will send the SPL fusing command to the PSP. So the case of
needing an SPL file override, but not updating the SPL fuses wasn't
supported before.
The SPL file in the amdfw part will be used by the PSP bootloader for
the anti-rollback feature which makes sure that the SPL file version
isn't lower than what is in the SPL fuses. For this the SPL file needs
to be present in the PSP directory table. The SPL version check happens
way before we're running code on the x86 cores. The SPL fusing PSP
command that can be sent by coreboot will tell the PSP to update the SPL
fuses so that the fused minimal SPL version will be updated to the
current SPL version.
Since the former HAVE_SPL_FILE option now only controls if the SPL
fusing command will be sent to the PSP mailbox, rename it to
PERFORM_SPL_FUSING to clarify what this will do and update the help text
correctly describe what this does.
TEST=With INCLUDE_CONFIG_FILE set to n, timeless builds for both Birman
with Phoenix APU and Skyrim result in identical binaries.

Instead of reporting all I2C controllers in the system as enabled in the
corresponding ACPI device's _STA method, report the I2C devices that are
disabled in the devicetree as disabled in the corresponding _STA method
too. This is done by returning the contents of the STAT variable inside
each device's scope in the DSDT that have a default value of 0 (device
not present/disabled). For all enabled and hidden I2C devices
i2c_acpi_fill_ssdt gets called which then writes 0xf (device enabled and
visible) or 0xb (device enabled, but hidden) to the STAT name inside the
same scope, but in the SSDT. This object in the SSDT will then override
the default in the DSDT resulting in the _STA method returning the
correct status of each device. The code was inspired by
commit 7cf9c7451808 ("soc/amd/*: Fix UART ACPI device status").

The data fabric also controls which PCI bus numbers get decoded to the
PCI root. In order for the resource allocator to know how the hardware
is configured, read the corresponding data fabric registers to get the
information that then gets passed to the allocator.
Picasso, Cezanne, Mendocino and Rembrandt only support one PCI segment
with 256 buses while the Phoenix and Glinda data fabric hardware has
support for more PCI segments. Due to this change, the register layout
is different and incompatible between those two, so introduce the
SOC_AMD_COMMON_BLOCK_DATA_FABRIC_MULTI_PCI_SEGMENT Kconfig option for a
SoC to specify which implementation is needed. At the moment, coreboot
doesn't have support for multiple PCI segments and the code doesn't
support PCI segments other than segment 0.
On Picasso the PCI bus number limit read back from the data fabric
register is 255 even though CONFIG_ECAM_MMCONF_BUS_NUMBER is set to 64,
so also make sure that the bus and limit returned by
data_fabric_get_pci_bus_numbers is within the expected limits.
TEST=PCI bus allocation still works on Mandolin (Picasso) and Birman
(Phoenix). Picasso has 64 PCI buses. coreboot puts this info into the
resource producer in _SB\PCI0\_CRS which the Linux kernel reads:
* coreboot: PCI0 _CRS: adding busses [0-3f]
* Linux: pci_bus 0000:00: root bus resource [bus 00-3f]
This matches the information in the ACPI MCFG table.

Prior to commit d1c0f958d198 ("acpi: Call acpi_fill_ssdt() only for
enabled devices"), uart_inject_ssdt() was used to set the ACPI status
(_STA) for both enabled and disabled devices. The aforementioned commit
limited it to being called only on enabled devices, which left disabled
devices without any _STA method at all -- which the OS assumes means
that the device is present and enabled.
To fix this, create the _STA method in the UART asl code for each port,
and set the return value to a name variable (STAT) which defaults to
0 (not present/disabled). Then, have uart_inject_ssdt() set STAT to
present and enabled (0xF) for UARTs actually present on the board.
TEST=build/boot google/skyrim (frostflow), dump ACPI tables, and verify
that _STA returns 0xF only for UARTs enabled in devicetree.

To have both the PCI function number and the register offset into the
config space of that function of the data fabric device in the data
fabric register definitions, introduce and use the DF_REG_ID, DF_REG_FN
and DF_REG_REG macros. The DF_REG_ID macro is used for register
definitions where both the function number and the register offset are
specified, and the DF_REG_FN and DF_REG_REG macros are used to extract
the function number and the register offset from the register defines.
This will allow having one define for accessing an indexed group of
registers that are on different functions of the data fabric device.
TEST=MMIO resources read from the data fabric's MMIO decode registers
don't change on Mandolin and the ACPI CRAT table is also identical.

On the mobile SoCs, SMN_IOHC_MISC_BASE_13B1 is the only IOHC misc base
address, but on for example Genoa it's the address of the IOHC misc base
of the second IOHC. Due to it not being the first one on Genoa, use 13B1
as part of the name instead of using an index of 0 which would look odd
in the Genoa case.

Instead of adding the new PCI IDs of the XHCI controllers in every new
chip generation to the pci_xhci driver, bind the driver to the internal
PCI devices of the XHCI controllers via the device ops statement in the
chipset devicetree. The PCI device function of the XHCI2 controller in
Mendocino can be either a dummy device or the XHCI controller, so the
device ops are attached to that device in the mainboard devicetree
instead. The Glinda code is right now just a copy of the Mendocino code,
so it'll change in the future, but for consistency the equivalent
changes to those in Mendocino are applied there too.
Since the device ops are now attached to the devices via the static
devicetree entry, also remove both the xhci_pci_driver struct and the
amd_pci_device_ids array from drivers/usb/pci_xhci/pci_xhci.c.

that points to same offset. Since the century field inside
RTC falls within the NVRAM space, and could interfere with
OPTION_TABLE, it is now guarded with config USE_PC_CMOS_ALTCENTURY.
There were no reference for the use of offset 0x48 for century.

Use get_pstate_core_freq instead of open-coding the calculations in
tsc_freq_mhz. In the case of the CPU frequency divider being 0,
get_pstate_core_freq will return 0; in this case that shouldn't happen,
TSC_DEFAULT_FREQ_MHZ will be used as frequency, since for the TSC
frequency it's better to err on the end of the expected frequency being
too high which will cause longer than expected delays instead of too
short delays.
Now that the code is using get_pstate_core_freq, this code is valid for
Glinda too, so also remove the comment on the

equivalents of ACPI_FADT_C2_NOT_SUPPORTED and ACPI_FADT_C3_NOT_SUPPORTED
so this also matches the AGESA behavior.
From the ACPI 6.4 spec: "Values provided by the _CST object override
P_LVLx values in P_BLK and P_LVLx_LAT values in the FADT."

The way the PSP_APCB_FILES list is created will always insert at least a
space into it. When tested by the if, this space will prevent the else
clause from ever running and never generate a build error.
Remove the non-functional check. Instead, mainboards should select
warn_no_apcb or die_no_apcb to generate a warning message or build error
if the APCB is missing.

Since it actually depends on the SoC type whether the old PSP
directory table pointer or the new comboable PSP directory table
pointer is used in EFS, get this information from the SoC ID instead
of passing the comboable flag for the SoCs that need to use the new
comboable PSP directory table pointer.
TEST=Binary identical on amd/majolica, pcengines/apu2, amd/gardenia
