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.

Set the maximum subordinate bus number of the domain to the last PCI bus
number that is decoded to this PCI root. This makes sure that the
resource allocator knows the maximum number of PCI buses on this PCI
root to not assign bus numbers to buses below this PCI root that aren't
routed to that PCI root.
Now that we have this info in the link list structure or the domain
device, we can pass the max_subordinate field to the
acpigen_resource_producer_bus_number call and can leave the subordinate
number after pci_domain_scan_bus is done unchanged instead of setting it
to the limit.
TEST=On Mandolin both the bus resource producer in _SB\PCI0\_CRS and the
PCI bus number allocation remain unchanged.

With reference to the Picasso PPR 55570 Rev 3.18, LegacyIoEn bit is 0 on
reset and setting it will enable the decoding of the following legacy IO
ports:
0x20, 0x21, 0xA0, 0xA1 (PIC);
0x40, 0x41, 0x42, 0x43, 0x61 (8254 timer);
0x70, 0x71, 0x72, 0x73 (RTC);
0x92.
Verstage does not use those legacy IO ports. Also newer SoCs like
Phoenix do not support Legacy I/O registers to access Power Management
registers and accessing them from PSP verstage causes a hang. Hence
enable legacy IO only on platforms that support it.
BUG=b::284984667
TEST=Build Myst BIOS image with PSP Verstage. Boot to OS successfully
with PSP verstage.

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.

Before add_io_regions only reported one fixed IO range to the resource
allocator that covered the whole IO range from 0x0000 to 0xffff. Instead
read the data fabric IO space decode base and limit address register
pairs to get the actual IO port decoding from the data fabric registers.
This will also help with adding support for multiple PCI root domains to
the common data fabric domain code so that Genoa can use it. In that
case each PCI root domain will only decode a part of the whole IO port
range.
Beware that the data fabric IO base and limit fields can contain values
that correspond to IO port addresses far outside of the addressable IO
port range. In case of Picasso, the IO limit read from the only enabled
DF IO range register would be 0x1ffffff after converting the raw data to
an IO port address. To not give the resource allocator wrong constraints
make sure that the IO limit we report will be at maximum 0xffff.
TEST=On Mandolin (Picasso) and Birman (Phoenix) the full range of IO
port addresses still gets reported as a domain IO resource producer like
before the patch:
DOMAIN: 0000 io: base: 0 size: 0 align: 0 gran: 0 limit: ffff done

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.

so they mustn't be reported as resource producers. To make sure that
this is the case, skip all resources that have the IORESOURCE_RESERVE

Commit 7a5dd781d147 ("soc/amd/common/data_fabric/domain: provide

already contained the bug, but since no MMIO range consumers were added
back then, the bug only became visible when commit 32169720bb67
("soc/amd/common/data_fabric/domain: report non-PCI MMIO resources")
added the reserved non-PCI MMIO resources to the domain device's
resources resulting in MMIO producer objects being generated for MMIO
consumers. Those producers that should have been consumers then
overlapped with the actual MMIO resource producers which caused Windows

This reverts commit e33d253793f6 ("soc/amd/common/block/acpi/ivrs: fix
missing IOAPIC[1] error").
Now that the per PCI root domain IOAPIC MMIO resource is reported on the
domain device, we can again probe the resource on the domain device
instead of the northbridge PCI device in that domain. This will make the
IVRS code compatible again with the work in progress Genoa SoC support.
TEST=Linux doesn't complain about the IOAPIC[1] missing in the IVRS on
Mandolin.

Call read_non_pci_resources from amd_pci_domain_read_resources to tell
the resource allocator about the non-PCI MMIO regions within the data
fabric MMIO regions so that the allocator won't place any PCI MMIO in
the same areas.
TEST=On Mandolin 3 new non-PCI resources get reported to the allocator:

Introduce the common read_non_pci_resources function to read the base
address of the non-PCI resources within the MMIO regions configured in
the data fabric registers and pass that info to the resource allocator.
Each SoC will need to provide implementations for get_iohc_misc_smn_base
and get_iohc_non_pci_mmio_regs in order for read_non_pci_resources to
know the SoC-specific base addresses, register offsets and MMIO region
sizes. In case of SoCs with only one PCI root domain, the domain
parameter of get_iohc_misc_smn_base will be unused, but in the case of
SoCs with more than one PCI root domains, this parameter will be used by
the SoC-specific code.

AGESA S3 restore needs to occur before SMM finalization/locking,
but it's a crapshoot as to which runs first since both use the same
BS_OS_RESUME/BS_ON_ENTRY boot state callback, and there's no way
to prioritize/force ordering.
To work around this, move the AGESA S3 resume call to the preceding
boot state (BS_OS_RESUME_CHECK) to ensure it runs first, and guard it
to ensure it only runs on the S3 resume path.
BUG=none
TEST=build/boot google/liara, verify S3 resume successful.

Because of the way that the CBFS filename is generated from the contents
of the microcode patch, if a duplicate microcode patch is included in
the build, the makefile would create a second copy of the name, which
doesn't work. This led to "odd" results where the other attributes of
the first copy were erased, causing cbfstool to fail. The cause of the
failure is not immediately obvious, and is a little difficult to track
down.
This patch causes an immediate failure and gives a reason as to the
cause of the issue.
When a failure is seen, this is the result:
File1: 3rdparty/amd_blobs/phoenix/psp/TypeId0x66_UcodePatch_PHXn4_A0.bin
File2: 3rdparty/amd_blobs/phoenix/psp/TypeId0x66_UcodePatch_PHX4_A0.bin

The eMMC entry in the IVRS table should only be generated if an eMMC
controller is present in the SoC.
Where the PCI_DEVFN(0x13, 1) is from is currently unclear to me. There
is no PCI device 0x13 on bus 0 and the eMMC controller is also an MMIO
device and not a PCI device, but this is what the reference code does.
My guess would be that it mainly needs to be a unique PCI device that
won't collide with any existing PCI device in the SoC. Add a comment
about this too.

This makes sure that the resource allocator won't use this address range
for anything else. In the systems I looked at, this was between the end
of the above 4GB memory and the beginning of the above 4GB PCI BAR MMIO
region, but better reserve it here so nothing else will get allocated
there if this expectation isn't met.
TEST=Reserved region is printed in the console logs:

BARs in the one PCI root domain from the corresponding data fabric MMIO

MMIO resources in areas that are decoded to the PCIe root complex. The
current code only covers the case of a system with one PCI root where
all PCI bus numbers belong to the only PCI root, all IO ports get

MMIO decode registers get decoded to the only PCI root. In future
patches, this will be extended to also support the multi PCI root case.

Currently the SPI ROM is mapped completely when the boot device is
initialized. That mapping remains active throughout the execution time
of PSP verstage. Every 1 MiB of mapped SPI ROM region consumes 1 TLB
Slot in PSP for use during memory mapped or DMA access. With 16 MiB of
mapped SPI ROM + FCH devices + 4 reserved TLB slots, 31 out of 32 total
TLB slots is consumed. This leaves almost no scope for future expansion.
With upcoming programs possibly using 32 MiB SPI ROM, PSP will run out
of TLB slots to support 32 MiB.
Hence instead of mapping the entire SPI ROM upfront, get the SPI ROM SMN
address during the boot device initialization. Update the boot device
region operations to map and unmap the SPI flash with the desired offset
and size using the SVC call. Then anytime a memory mapped SPI ROM access
is performed: map the required area, read the data and immediately unmap
the area. There is no update required when using CCP DMA, since the
concerned SVC call performs mapping and unmapping of the required SPI
flash area implicitly.
With these changes, maximum of 8 slots(size of RO section) might get
used at any point in time during the PSP verstage execution.

Commit c7b8809f155a ("soc/amd/common/block/gfx: Use TPM-stored hash
for vbios cache validation") replaced checking the vbios signature
(first two bytes) with checking against a TPM-stored hash, but there
exists an edge case where the empty cache can be hashed and therefore
never updated with the correct vbios data. To mitigate this, re-add
the signature check to ensure that an empty cache will never be hashed
to TPM.
BUG=b:255812886
BRANCH=skyrim
TEST=build/boot skyrim w/selective GOP enabled, flash full firmware
image, ensure GOP driver is run until cache updated with valid data
and hashed to TPM.
