Furquan Shaikh 493937e1d6 coreboot tables: Add SPI flash memory map windows to coreboot tables
This change adds details about the memory map windows to translate
addresses between SPI flash space and host address space to coreboot
tables. This is useful for payloads to setup the translation using the
decode windows already known to coreboot. Until now, there was a
single decode window at the top of 4G used by all x86
platforms. However, going forward, platforms might support more decode
windows and hence in order to avoid duplication in payloads this
information is filled in coreboot tables.

`lb_spi_flash()` is updated to fill in the details about these windows
by making a call to `spi_flash_get_mmap_windows()` which is
implemented by the driver providing the boot media mapping device.

Jes Klinke f99f589ea9 drivers/i2c/tpm: Unconditionally allow I2C TPM ACPI node
DRIVER_I2C_TPM_ACPI is used to enable the "driver" needed for coreboot
to present a TPM node in the devicetree.  It would usually only do so,
if coreboot itself is communicating with the TPM via I2C (I2C_TPM).
However, technically, there is no dependency.

In order to not show the ACPI option in menuconfig if the board is not
using I2C, a dependency was declared in Kconfig.  However, the same can
be achieved without making it an error to manually declare
DRIVER_I2C_TPM_ACPI without I2C_TPM.

For Volteer, we have just such a need, since it has two "sub-variants"
sharing the same overridetree.cb, one having SPI TPM and another having
I2C TPM.  The former will have a disabled ACPI node representing the I2C
TPM, while its Kconfig is such that coreboot itself does not have I2C
TPM support.

In order to export even a disabled ACPI node representing the I2C
connected TPM, coreboot needs DRIVER_I2C_TPM_ACPI.  Hence, that will
have to be enabled in a case where coreboot does not have I2C_TPM (for
one of the two sub-variants, namely volteer2).

Nothing gets inlined, for example is_smp_boot() no longer

Also the addresses of relocatable ramstage are currently
not normalised on the logs, so util/genprof would be unable
dress those.

Julius Werner 834b3ecd7c cbfs: Simplify load/map API names, remove type arguments
This patch renames cbfs_boot_map_with_leak() and cbfs_boot_load_file()
to cbfs_map() and cbfs_load() respectively. This is supposed to be the
start of a new, better organized CBFS API where the most common
operations have the most simple and straight-forward names. Less
commonly used variants of these operations (e.g. cbfs_ro_load() or
cbfs_region_load()) can be introduced later. It seems unnecessary to
keep carrying around "boot" in the names of most CBFS APIs if the vast
majority of accesses go to the boot CBFS (instead, more unusual
operations should have longer names that describe how they diverge from
the common ones).

cbfs_map() is paired with a new cbfs_unmap() to allow callers to cleanly
reap mappings when desired. A few new cbfs_unmap() calls are added to
generic code where it makes sense, but it seems unnecessary to introduce
this everywhere in platform or architecture specific code where the boot
medium is known to be memory-mapped anyway. In fact, even for
non-memory-mapped platforms, sometimes leaking a mapping to the CBFS
cache is a much cleaner solution than jumping through hoops to provide
some other storage for some long-lived file object, and it shouldn't be
outright forbidden when it makes sense.

Additionally, remove the type arguments from these function signatures.
The goal is to eventually remove type arguments for lookup from the
whole CBFS API. Filenames already uniquely identify CBFS files. The type
field is just informational, and there should be APIs to allow callers
to check it when desired, but it's not clear what we gain from forcing
this as a parameter into every single CBFS access when the vast majority
of the time it provides no additional value and is just clutter.

Michael Niewöhner 59f06ada68 drivers/intel/fsp2_0: introduce possibility of using a full FD binary
Currently, setting a custom FSP binary is only possible by using split
FSP-T/M/S FD files. This change introduces the possibility to pass a
combined FD file (the "standard" FSP format).

This is done by adding a new boolean Kconfig FSP_FULL_FD, specifying
that the FSP is a single FD file instead of split FSP-T/M/S FD files,
and making FSP_FD_PATH user-visible when the option is chosen. In this
case, the other options for split files get hidden.

When the user chooses to use a full FD file instead of the split ones,
the FD file gets split during build, just like it is done when selecting
the Github FSP repo (FSP_USE_REPO).

Test: Supermicro X11SSM-F builds and boots fine with custom FSP FD set.

Shelley Chen 6615c6eaf7 mrc_cache: Move code for triggering memory training into mrc_cache
Currently the decision of whether or not to use mrc_cache in recovery
mode is made within the individual platforms' drivers (ie: fsp2.0,
fsp1.1, etc.).  As this is not platform specific, but uses common
vboot infrastructure, the code can be unified and moved into
mrc_cache.  The conditions are as follows:

  1.  If HAS_RECOVERY_MRC_CACHE, use mrc_cache data (unless retrain
      switch is true)
  2.  If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_BOOTBLOCK, this
      means that memory training will occur after verified boot,
      meaning that mrc_cache will be filled with data from executing
      RW code.  So in this case, we never want to use the training
      data in the mrc_cache for recovery mode.
  3.  If !HAS_RECOVERY_MRC_CACHE && VBOOT_STARTS_IN_ROMSTAGE, this
      means that memory training happens before verfied boot, meaning
      that the mrc_cache data is generated by RO code, so it is safe
      to use for a recovery boot.
  4.  Any platform that does not use vboot should be unaffected.

Additionally, we have removed the
MRC_CLEAR_NORMAL_CACHE_ON_RECOVERY_RETRAIN config because the
mrc_cache driver takes care of invalidating the mrc_cache data for
normal mode.  If the platform:
  1.  !HAS_RECOVERY_MRC_CACHE, always invalidate mrc_cache data
  2.  HAS_RECOVERY_MRC_CACHE, only invalidate if retrain switch is set

	device pci xx.y on end # CNVi PCI device
end

Furquan Shaikh 6017abbc2c drivers/wifi/generic: Split wifi_generic_fill_ssdt into two functions
This change splits `wifi_generic_fill_ssdt()` into following two
functions:
1. `wifi_ssdt_write_device()`: This function writes the device, its
address, _UID and _DDN.

2. `wifi_ssdt_write_properties()`: This function writes the properties
for WiFi device like _PRW, regulatory domain and SAR.

This split is done so that the device write can be skipped for
CNVi devices in follow-up CLs. It will allow the SoC controller
representation for CNVi PCI device to be consistent with other
internal PCI devices in the device tree i.e. not requiring a
chip driver for the PCI device.

Because of this change, _PRW and SAR will be seen in a separate
block in SSDT disassembly, but it does not result in any functional
change.

Observed difference:
Before:
