<stdarg.h> header is used to define macros for handling variable
argument lists in functions like printf. It does not depend on the string
or memory manipulation functions provided by <string.h>.
So let follow conventions and include only the necessary headers in each
header file.

Rename the 'irq' element of the pci_routing_info struct to 'bridge_irq'
to better describe what it's doing. This struct element contains the
number of the northbridge IOAPIC IRQ input the bridge IRQ is connected
to signal power management or error reporting IRQs. Right now, coreboot
doesn't put this information into the ACPI bytecode.

When switching back and forth between 32 to 64 bit mode, for example to
call a 32-bits FSP or to call the payload, new page tables in the
respective stage will be linked.
The advantages of this approach are:
- No need to determine a good place for page tables in CBFS that does
not overlap.
- Works with non memory mapped flash (however all coreboot targets
currently do support this)
- If later stages can use their own page tables which fits better with
the vboot RO/RW flow
A disadvantage is that it increases the stage size. This could be
improved upon by using 1G pages and generating the pages at runtime.
Note: qemu cannot have the page tables in the RO boot medium and needs
to relocate them at runtime. This is why keeping the existing code with
page tables in CBFS is done for now.
TEST: Booted to payload on google/vilbox and qemu/q35

This does the following:
- Top align the bootblock so that the only the memory needed gets used.
This might slightly reduce the time the PSP needs to decompress the
bootblock in memory
- Use a memory directive to assert that the 16bit code is inside the top
64K segment
- Use the program counter less. While the BDF linker is happy about
running the program counter backwards, LLD is not. There is no
downside to this.
- Use a symbol rather that the program counter for sections. LLD gets
confused when (.) is used along with '<': it places the section at the
start of the memory region, rather than at the program counter. Using
a variable name works around this.
- Use a 'last_byte' section to make sure the first instruction is at
0xfff0. Both the BDF and the LLD linkers seems to work well with this
code
TEST: Both BFD and LLD are able to link the bootblock

Even though it has an 'amd_' prefix, the amd_pci_domain_fill_ssdt
implementation doesn't contain any AMD-specific code and can also be
used by other SoCs. So factor it out, move the implementation to
src/acpi/acpigen_pci_root_resource_producer.c, and rename it to
pci_domain_fill_ssdt. When a SoC now assigns pci_domain_fill_ssdt to its
domain operation's acpi_fill_ssdt function pointer, the PCI domain
resource producer information will be added to the SSDT.

In commit 30f36c35e75a ("soc/amd: rework DRAM and fixed resource
reporting") the reporting of the DRAM resources was moved from the
northbridge PCI device to the domain device. amd_pci_domain_fill_ssdt
didn't skip those DRAM resources when generation the resource producer
ranges which made Windows 10 very unhappy when it tried to evaluating
the ACPI tables causing it to reboot in a loop. To fix this, add a check
to also skip the resources that have the IORESOURCE_STORED flag set when
generating the resource producer ranges for the PCI root.

Drop the unneeded data_fabric_set_mmio_np function and the corresponding
SOC_AMD_COMMON_BLOCK_DATA_FABRIC_NP_REGION Kconfig symbol. In systems
with only one FCH, its MMIO region will be subtractively decoded and
there's no need to add a non-posted data fabric MMIO region after the
FSP/openSIL has already configured the data fabric decode windows. In
systems with more than one FCH, openSIL will already take care of
initializing everything for the additional FCH, so we also won't need to
do anything in that case. Since dropping this function also removes both
data_fabric_print_mmio_conf calls before and after adding the unneeded
non-posted MMIO region, replace the data_fabric_set_mmio_np call with a
data_fabric_print_mmio_conf call to still print the data fabric MMIO
decode regions set up by the FSP/openSIL.

Multiple links are unused throughout the tree and make the code more
confusing as an iteration over all busses is needed to get downstream
devices. This also not done consistently e.g. the allocator does not
care about multiple links on busses. A better way of dealing multiple
links below a device is to feature dummy devices with each their
respective bus.
This drops the sconfig capability to declare the same device multiple
times which was previously used to declare multiple links.

Factor out acpi_add_fsp_tables from the soc_acpi_write_tables function
and move the remaining parts of the soc_acpi_write_tables function to
the SoC's acpi.c. This aligns the other family 17h/19h SoCs more with
Genoa and only leaves the FSP-specific code in agesa_acpi.c which will
be made common in a following patch. I decided against also renaming
agesa_acpi.c to acpi_fsp.c, since that would have made the diff less
readable and the files get deleted in a following patch anyway.

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.

in PSP, this approach hit the limit on systems using 32 MiB SPI ROM.
Therefore regions in SPI ROM were mapped on need basis. This works well
on Picasso, Mendocino and Phoenix SoCs. But unfortunately this causes
boot hangs in Cezanne SoC. Add a configuration to map the entire SPI ROM
and enable it in Cezanne SoC. For other SoCs, keep the configuration
disabled so that only the required SPI ROM region is mapped.

Drop the hda_soc_ssdt_quirks function since it doesn't apply for any of
the SoCs supported by the Stoneyridge code which was the only SoC
implementing it. This code was added when commit 91a7abf25c72
("soc/amd/hda: Move HDA PCI device from DSDT to SSDT") rewrote the code
originally added in commit 1587dc8a2b4d ("soc/amd/stoneyridge: Add
northbridge support") as a copy from northbridge/amd/pi/00670F00. This
code was moved around in commit 6580408a7e0a ("amd/pi/hudson: Move audio
to northbridge"), since the HDA controller was moved from the FCH to the
northbridge complex. When the controller was moved, the PCI config space
interface also changed, so those bits are no longer the DisableNoSnoop,
DisableNoSnoopOverride, and EnableNoSnoopRequest bits of the Misc
Control register of the HDA controller, but some bits within the
ClassCodeW field of the ACGAZ Mirrot Reg Ctrl 0 register.
BKDG #55072 Rev 3.04 (Stoneyridge), BKDG #50742 Rev 3.08 (family 15h
model 60h-6fh / 00670F00), and BKDG #52740 Rev 3.05 (family 16h model
30h-3fh) were used as a reference. Only the SoC with BKDG #52740 still
has the HDA controller in the FCH; the other two have it in the
northbridge.

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.

AMD's Audio CoProcessor handles i2s/tdm audio, and is located on the
GPU.
On Windows the PCIe device for the GPU is owned by the AMD proprietary
driver, hence a separate device has to be added for the ACP driver.
Fortunately since IOMMU is disabled on STONEY, the driver itself can
pull BAR5 from the GPU and use that to initialize, so no special
configuration is required in ACPI other than the ID.

Crypto Engine in PSP prefers the buffer from Static RAM (SRAM). Hence if
a buffer comes from within SRAM address range, then it is passed
directly to Crypto Engine. Otherwise a bounce bufer from the stack is
used. But on SoCs like Picasso where PSP Verstage stack is mapped to a
virtual address space this check fails causing a bounce buffer to be
used and hence a stack overflow. Fix this issue by assuming that the
buffer comes from the SRAM always in such SoCs and pass the buffer
directly to crypto engine.

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.

Instead of having the get_usable_physical_address_bits function that
only got used in the data fabric domain resource reporting code, drop
this function, select RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT in the
common AMD non-CAR CPU and rename get_sme_reserved_address_bits to
get_reserved_phys_addr_bits so that the common cpu_phys_address_size
function will return the correct number of usable physical address bits
which now can be used everywhere. The common AMD CAR CPU support is only
selected by Stoneyridge which doesn't support secure memory encryption,
so RESERVED_PHYSICAL_ADDRESS_BITS_SUPPORT isn't selected by the
SOC_AMD_COMMON_BLOCK_CAR Kconfig option.
Before only the MMIO region reporting took the reserved physical address
bits into account, but now also the MTRR calculation will take those
reserved bits into account. See the AMD64 Programmers Manual volume 2
(document number 24593) for details. Chapter 7.10.5 from revision 3.41
of this document was used as a reference. The MTRR handling code in
older Linux kernels complains when the upper reserved bits in the MTRR
mask weren't set, but sets them after complaining and then continues to
boot. This issue is no longer present in version 6.5 of the Linux
kernel.
The calculation of the TSEG mask however still needs to take all
physical bits into account, including the ones reserved for the memory
encryption. When not setting the reserved bits in the TSEG mask, the
Mandolin board with a Picasso APU won't boot to the OS any more due to
not returning from SeaBIOS calling into the VBIOS. Haven't root-caused
what exactly causes this breakage, but I think previously when something
else was wrong with the SMM initialization, also something went wrong
when calling into the VBIOS.
TEST=Ubuntu 2023.10 nightly build boots on Mandolin via SeaBIOS and EDK2
and Windows 10 boots on it via EDK2.
TEST=On Ubuntu 2022.04 LTS, the kernel complained with the following
warning, but it still continues the boot process as described above:

the MMIO config in the SOC_AMD_COMMON_BLOCK_DATA_FABRIC_EXTENDED_MMIO
case which wasn't handled properly before.
TEST=Console output from this function doesn't change on Mandolin:

data_fabric_disable_mmio_reg and data_fabric_find_unused_mmio_reg are
only used by data_fabric_set_mmio_np in the same file, so make them
static and drop the prototype from the header file.

x86 pre-memory stages do not support the `.data` section and as a
result developers are required to include runtime initialization code
instead of relying on C global variable definition.
To illustrate the impact of this lack of `.data` section support, here
are two limitations I personally ran into:
1. The inclusion of libgfxinit in romstage for Raptor Lake has
required some changes in libgfxinit to ensure data is initialized at
runtime. In addition, we had to manually map some `.data` symbols in
the `_bss` region.
2. CBFS cache is currently not supported in pre-memory stages and
enabling it would require to add an initialization function and
find a generic spot to call it.
Other platforms do not have that limitation. Hence, resolving it would
help to align code and reduce compilation based restriction (cf. the
use of `ENV_HAS_DATA_SECTION` compilation flag in various places of
coreboot code).
We identified three cases to consider:
1. eXecute-In-Place pre-memory stages
- code is in SPINOR
- data is also stored in SPINOR but must be linked in Cache-As-RAM
and copied there at runtime
2. `bootblock` stage is a bit different as it uses Cache-As-Ram but
the memory mapping and its entry code different
3. pre-memory stages loaded in and executed from
Cache-As-RAM (cf. `CONFIG_NO_XIP_EARLY_STAGES`).
eXecute-In-Place pre-memory stages (#1) require the creation of a new
ELF segment as the code segment Virtual Memory Address and Load Memory
Address are identical but the data needs to be linked in
cache-As-RAM (VMA) but to be stored right after the code (LMA).
Here is the output `readelf --segments` on a `romstage.debug` ELF
binary.
Program Headers:
Type Offset VirtAddr PhysAddr FileSiz MemSiz Flg Align
LOAD 0x000080 0x02000000 0x02000000 0x21960 0x21960 R E 0x20
LOAD 0x0219e0 0xfefb1640 0x02021960 0x00018 0x00018 RW 0x4
Section to Segment mapping:
Segment Sections...
00 .text
01 .data
Segment 0 `VirtAddr` and `PhysAddr` are at the same address while they
are totally different for the Segment 1 holding the `.data`
section. Since we need the data section `VirtAddr` to be in the
Cache-As-Ram and its `PhysAddr` right after the `.text` section, the
use of a new segment is mandatory.
`bootblock` (#2) also uses this new segment to store the data right
after the code and load it to Cache-As-RAM at runtime. However, the
code involved is different.
Not eXecute-In-Place pre-memory stages (#3) do not really need any
special work other than enabling a data section as the code and data
VMA / LMA translation vector is the same.
TEST=#1 and #2 verified on rex and qemu 32 and 64 bits:
- The `bootblock.debug`, `romstage.debug` and
`verstage.debug` all have data stored at the end of the `.text`
section and code to copy the data content to the Cache-As-RAM.
- The CBFS stages included in the final image has not improperly
relocated any of the `.data` section symbol.
- Test purposes global data symbols we added in bootblock,
romstage and verstage are properly accessible at runtime
#3: for "Intel Apollolake DDR3 RVP1" board, we verified that the
generated romstage ELF includes a .data section similarly to a
regular memory enabled stage.

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").
TEST=On Mandolin all I2C controllers are disabled and with this patch
none shows up in the Windows 10 device manager. When enabling an I2C
controller in the devicetree for testing, it shows up again in the
Windows device manager.

Per the PSP team, this field in the transfer buffer isn't used anymore
and always set to zero, causing devices to incorrectly report having
pre-production silicon.
