Since the Kconfig default for boolean options is already 'n', there's no
need to add that default to the option. Still kept the 'default n' for
the 3 options that result in fuses inside the SoC to be burnt
(PERFORM_RPMC_PROVISIONING, PERFORM_SPL_FUSING and
PSP_PLATFORM_SECURE_BOOT) to point out the fact that that's not selected
by default more clearly.

Add the data structures used for the command buffers for the PSP SMI
commands to increment and request the state of the monotonic counters in
the SPI flash. These data structures are specific to the PSP SMI mailbox
interface and not the data structures from the RPMC specification. The
AGESA code was used as a reference.

In the case where the x86 owns the SPI controller and the RPMC feature
is used, the PSP will send an SMI to the x86 side for it to send the
RPMC increment monotonic counter and RPMC request monotonic counter
commands to the SPI flash and return the result to the PSP. Add stubs
as handlers for those two PSP SMI commands.

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.

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

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.

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.

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.

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.

To avoid having constructs like 'dev->path.domain.domain' in the SoC
code, create the 'dev_get_domain_id' helper function that returns the
domain ID of either that device if it's a domain device or the
corresponding domain device's domain ID, and use it in the code.
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.

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.

In AMD platforms, the bit 4 of CMOS's Register A (0x0a) is DV0 bank
selection (0 for Bank 0; 1 for Bank 1) [1]. Since the MC146818 driver
accesses VBNV via Bank 0, the bit must be cleared before we can save
VBNV to CMOS in verstage.
Usually there's no problem with that, because the Register A is
configured in cmos_init() in ramstage. However, if CMOS has lost power,
then in the first boot after that, the bit may contain arbitrary data in
verstage. If that bit happens to be 1, then CMOS writes in verstage will
fail.
To fix the problem, define vbnv_platform_init_cmos() to call
cmos_init(0), which will configure the Register A and therefore allow
saving VBNV to CMOS in verstage.

When we tried to add CMOS support to PSP verstage (CB:83495), the clang
builds failed on boards with cezanne SoC (such as Guybrush), due to
over-sized verstage. On the other hand, there is no such problem for gcc
builds on the same boards.
Building PSP verstage by clang generates much larger verstage size (81K)
compared with using gcc (67K). To unblock adding features to verstage,
temporarily enable -Oz for clang builds.

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.

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

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.
TEST=Windows 10 now successfully boots and reboots again on Mandolin

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.
TEST=Mandolin still boots successfully

Make the initialization of the IOAPIC(s) in the PCI root(s) common

implementation from the Genoa code that supports multiple PC roots is
moved to the common AMD code. All other family 17h+ SoCs are then
adapted to use the common code. For those non-Genoa SoCs, the

device to the domain device above to match Genoa.

Since reporting the PCI ECAM MMCONF MMIO region and the IO ports for the

common add_pci_cfg_resources function that reports both and gets called

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

This drops the sconfig capability to declare the same device multiple

be done inside the FSP driver code. Since only some SoCs call

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.
