This patch removes the SOC_INTEL_GFX_MBUS_JOIN configuration option.
Support for fast modeset joining has been added to the mainline i915
kernel driver (https://patchwork.freedesktop.org/series/130480/),
making this coreboot-specific workaround unnecessary.

Now that the PSP SMI handler for flash access is also implemented for
the PSP generation 1, the PSP SMI handler can be added to the
Stoneyridge code too. The actual PSP SMI handler code will only be added
to the build when SOC_AMD_COMMON_BLOCK_PSP_SMI is selected which isn't
the default case, so this patch doesn't change the current behavior
unless that option is also selected. This SMI handler mainly added for
completeness since the PSP firmware blobs released for Stoneyridge are
probably lacking the corresponding PSP-side code to send the PSP SMI to
the host. At least if I remember correctly the PSP bootloader release
for Stoneyridge has the ability to load the secure OS removed and since
the secure OS is the runtime component, some part of that is probably
what's sending those SMIs to the host. If there are some other PSP
bootloader builds that support loading the secure OS, this patch might
still be useful for those.

Add helper functions to send the PSP commands to query the fTPM and
PSP capability bits as well as the HSTI state. All SoCs using any PSP
generation support the MBOX_BIOS_CMD_PSP_FTPM_QUERY command and some
generation 1 and all generation 2 PSP SoCs support the
MBOX_BIOS_CMD_HSTI_QUERY command, so implement those two in the common
psp.c. Only PSP generation 2 supports the MBOX_BIOS_CMD_PSP_CAPS_QUERY
command, so implement that one in psp_gen2.c.
This code is ported and modified from

Rename MBOX_BIOS_CMD_PSP_QUERY to MBOX_BIOS_CMD_PSP_FTPM_QUERY to bring
it a bit more in line with document #55758 revision 2.04 and to avoid
confusion when another command is added in a follow-up patch. In
document #54267 revision 1.06 this command is called
MBOX_BIOS_CMD_PSP_QUERY and in document #55758 revision 2.04 it's called
MBOX_BIOS_CMD_FTPM_QUERY, so just name it MBOX_BIOS_CMD_PSP_FTPM_QUERY
in coreboot which should be the least confusing name for it that still
somewhat aligns with the documentation.

The request buffer data structures differ between the PSP generation 1
and 2 in the way that the generation 2 added the 64 bit target NV ID
field right at the beginning of the request buffer data structures. In
order to make the data structure definitions common, remove the
target_nv_id struct element via the preprocessor in case the
SOC_AMD_COMMON_BLOCK_PSP_GEN2 option isn't selected. Since the request
buffer data structures are now common for both generations, also remove
the 'v2' from the struct names.

When the config of MCU firmware blob such as CONFIG_SPM_FIRMWARE is
non-empty, we should always expect the file to exist. Similarly, since
the device is unlikely to boot without the DRAM blob (assuming MRC_CACHE
doesn't contain valid memory training data), dram.elf should always
exist as well.
Therefore, remove the check for the existence of the blobs. Build would
fail if any of the blobs is missing.

This patch extends the eSOL implementation on Alder Lake to render text
messages during late CSE sync (from ramstage).
Currently, the eSOL is limited to the early boot phase (until romstage)
and only displays FSP-M memory training warnings or messages during
early CSE sync (at romstage).
Platforms like Nissa/Nirul and Trulo, which use CSE sync from ramstage,
cannot display any eSOL messages, resulting in a brief black screen
during CSE firmware updates.
This patch implements the following logic to scale eSOL for late CSE
sync (at ramstage) without recompiling eSOL code for ramstage:
1. During boot, check if the MRC cache is available. This indicates the
need for memory/DRAM training and triggers an eSOL message.
2. For CSE lite SKUs (applicable to CrOS), leverage the
`is_cse_fw_update_required` API to check if the current CSE RW
firmware version differs from the CBFS metadata file version.
If so, trigger an eSOL message indicating a CSE sync is required.
3. If either condition #1 and/or #2 is true, the AP firmware renders
an eSOL text message using LibGfxInit for the Alder Lake platform.

This patch prevents the eSOL screen from being wiped out on Alder Lake

Currently, the eSOL only functions during the early boot phase (until

A future patch will ensure the eSOL remains relevant for CSE sync in

Commit 16ab9bdcd578612bb3822373547f939eb90afd82 ("soc/intel/common:
Calculate and configure SF Mask 2") breaks the computation of the
number of ways and as result, all the derived masks. It results in MSR
such as `IA32_L3_MASK_1' to be improperly programmed yielding
unpredictable NEM issues such as hangs.
Indeed, this commit has introduced a backup of 0x1 into %edx before
comparing the requested cache-as-RAM size against the way size. When
the requested cache-as-RAM is larger, it reaches the second part of
the algorithm which computes the necessary number of ways to fit the
requested cache-as-RAM.
This algorithm uses the `div' instruction. Per specification, the div
instruction divides the 64 bits combination of %edx and %eax register.
Since 0x1 got backed up in %edx and assuming a
`CONFIG_DCACHE_RAM_SIZE' of 0x200000, we end up dividing 0x100200000
by the way size instead of 0x200000 which result in a necessary number
of ways of 4098 for a way size of 0x100000.
This commit clears the %edx register before calling the `div'
instruction.

This patch adds a generic config option, SOC_INTEL_COMMON_DEBUG_CONSENT,
to control the debug interface on Intel SoCs. This eliminates the need
for SoC-specific config options like SOC_INTEL_<SOC_NAME>_DEBUG_CONSENT.
Default values are provided for various debug types:
- 0: Disabled
- 1: Enabled (DCI OOB + [DbC])
- 2: Enabled (DCI OOB)
- 3: Enabled (USB3 DbC)
- 4: Enabled (XDP/MIPI60)
- 5: Enabled (USB2 DbC)
- 6: Enabled (2-wire DCI OOB)
- 7: Manual
Specific SoCs can override the SOC_INTEL_COMMON_DEBUG_CONSENT value
using SoC config override methods.

We introduce two new functions to create region objects. They allow us
to check for integer overflows (region_create_untrusted()) or assert
their absence (region_create()).
This fixes potential overflows in region_overlap() checks in SMI
handlers, where we would wrongfully report MMIO as *not* overlapping
SMRAM.
Also, two cases of strtol() in parse_region() (cbfstool), where the
results were implicitly converted to `size_t`, are replaced with the
unsigned strtoul().
FIT payload support is left out, as it doesn't use the region API
(only the struct).

Before 'handle_psp_command' calls any of the functions in this file, it
make sure that the 'size' field in the command buffer's header doesn't
indicate that the command buffer is larger than the SMM memory region
reserved for it.
The read/write command buffer has a 'num_bytes' field to indicate how
many bytes should be read from the SPI flash and put into the data
buffer within the command buffer or how many bytes from this buffer
should be written to the flash. While we should be able to assume that
the PSP won't send us malformed command buffer, we should still better
check this just to be sure.

Detect the block size of the SPI flash and number of flash blocks
reserved for the flash region corresponding to the 'target_nv_id' field
in the command buffer. This information is then written to the
corresponding fields in the command buffer. Since detecting the flash
chip still might result in accesses to it, make sure that it's available
for use and not currently used by an OS driver. Since this code is
inside the SMI handler, we don't have to worry about this code to be
interrupted, so we don't need to set some bit to tell other code that
we're currently using the SPI controller in the SMI handler.
This patch is a modified version of parts of CB:65523.

The SPI_SEMAPHORE_DRIVER_LOCKED bit in the SPI_MISC_CNTRL register
doesn't affect the hardware, but it re-used by AMD as a semaphore to
synchronize the access to the SPI controller between SMM and non-SMM
software like an OS-level driver. Since it doesn't affect the hardware,
it's marked as reserved in the PPRs. Add the 'spi_controller_available'
helper function to check this bit to see if some software or driver
outside of SMM is currently using the SPI flash controller to avoid
interfering with that operation.
This patch is a slightly reworked version of parts of CB:65523.

Add 'find_psp_spi_flash_device_region' to get a pointer to the spi_flash
struct of the SPI flash used in the system and the region_device struct
for the target FMAP region specified by the target NV ID from the PSP
to x86 mailbox command. In order to have small patches, the newly added

When the PSP wants to access the SPI flash during runtime, but isn't the
owner of the SPI flash controller, it sends an SMI to the x86 side. The
corresponding SMI handler then checks the P2C (PSP to core) mailbox for
the command and data, processes the command, and if needed puts the
requested data into the P2C buffer.
The P2C mailbox is a memory region in TSEG aka SMM memory. Both location
and size are communicated to the PSP via the PSP SMM info mailbox
command which is sent right after mpinit is done.
This commit adds the code to access the P2C mailbox to the PSP SMI
handler code, but the handling of the actual mailbox commands the PSP
sends to the SMI handler is added in later patches to keep the patch
size manageable.
This patch is a heavily reworked version of parts of CB:65523.

Clock Power Management, ASPM and L1 Substates have been
configured the same way since Skylake. The main control to
enable or disable is Kconfig, and then the level can be overridden
in devicetree.
Despite the UPDs remaining the same since Skylake, this is not the
case for Alder Lake, Raptor Lake and Meteor Lake.
Taking `starlabs/starbook` as an example, at the time of this
commit it has PCIEXP_CLK_PM, PCIEXP_ASPM and PCIEXP_L1_SUB_STATE
enabled.
On Comet Lake, this results in the correct configuration, verified
with the lspci command:
```
LnkCap: Port #0, Speed 5GT/s, Width x1, ASPM L1, Exit Latency L1 <8us
ClockPM+ Surprise- LLActRep- BwNot- ASPMOptComp+
LnkCtl: ASPM L1 Enabled; RCB 64 bytes, Disabled- CommClk+
ExtSynch- ClockPM+ AutWidDis- BWInt- AutBWInt-
```
On Raptor Lake:
```
LnkCap: Port #0, Speed 16GT/s, Width x4, ASPM L1, Exit Latency L1 <64us
ClockPM- Surprise- LLActRep- BwNot- ASPMOptComp+
LnkCtl: ASPM Disabled; RCB 64 bytes, Disabled- CommClk+
```
Clock Power Management, ASPM and L1 Substates are also not configured
for CPU root ports.
Add helper functions to configure these correctly based on Kconfig, but
retain the capability to override the specific levels from devicetree.

If this function is called with a device other than PCI or domain type,
it won't have a domain number. In order to not need to call 'die',
'dev_get_domain_id' will print an error and return 0 which is a valid
domain number. In that case, the calling code should be fixed.

Now that we have a get_psp_mmio_base function that will work on all SoCs
that use the psp_gen2 code, we can move back to accessing the PSP
registers via their MMIO mapping. This sort-of reverts
commit 198cc26e4951 ("soc/amd/common/block/psp/psp_gen2: use SMN access
to PSP").
When doing SMN accesses from the SMI handler after the OS has taken over
ownership of the platform, there's the possibility to cause trouble by
clobbering the SMN access index register from SMM. So that should be
either avoided completely or the SMI code needs to save and restore the
original contents of the SMN index register.
The PSP MMIO base will be set up by the FSP before the resource
allocation in coreboot and be treated like a fixed resource by the
allocator. The first SMI where corresponding handler calls
'get_psp_mmio_base' happens when ramstage triggers the APM_CNT_SMMINFO
SMI right after mpinit which happens after the resource allocation. So
the PSP MMIO base address is expected to be configured and so the
'get_psp_mmio_base' function will cache the base address and won't need
to do any SMN access in subsequent calls that might happen after the OS
has take over control.
This isn't currently an issue, since the only PSP mailbox command from
the SMI handler after coreboot is done and the OS has taken over will
be during the S3/S4/S5 entry, and this will be triggered by the OS as
the last step after it is done with all its preparations for suspend/
shutdown. There will however be future patches that add SMI-handlers
which can send PSP mailbox commands during OS runtime, and so we have
to make sure we don't clobber the SMN index register.
TEST=PSP mailbox commands are still sent correctly on Mandolin.

This sort-of reverts commit 00ec1b9fc7ba ("soc/amd/common/block/psp/
psp_gen2: simplify soc_read_c2p38") and is done as a preparation to
switch back to using the MMIO access to the PSP mailbox registers.

Add get_psp_mmio_base which reads the PSP MMIO base address from the
hardware registers. Since this function will not only be called in
ramstage, but also in SMM, we can't just look for the specific domain
resource consumer like it is done for the IOAPICs in the northbridge,
but have to get this base address from the registers. In order to limit
the performance impact of this, the base address gets cached in a static
variable if an enabled PSP MMIO base register is found. We expect that
this register is locked when it was configured and enabled; if we run
into the unexpected case that the PSP MMIO register is enabled, but not
locked, set the lock bit of the corresponding base address register to
be sure that it won't change until the next reset and that the hardware
value can't be different than the cached value.
This is a preparation to move back to using MMIO access to the PSP
registers and will also enable cases that require the use of the MMIO
mapping of the PSP registers.

The PSP code introduced in a following patch needs both SoC-specific
functions get_iohc_info and get_iohc_non_pci_mmio_regs to also be
available in SMM, so add those compilation units to the corresponding
target.

Instead of implementing the functions get_iohc_misc_smn_base and
get_iohc_fabric_id in the SoC code, move those functions to the common
AMD code, and implement get_iohc_info in the SoC code that returns a
pointer to and the size of a SoC-specific array of domain_iohc_info
structs that contains the info needed by the common code instead. This
allows to iterate over the domain_iohc_info structs which will be used
in a later patch to find the PSP MMIO base address in both ramstage and
smm.
TEST=Mandolin still boots and all non-PCI MIO resources are still
reported to the resource allocator
