Chromebooks normally run with non-serial enabled firmware because
writing to the UART console is very slow. This unfortunately makes
debugging boot errors more difficult. We tend to rely on port 80s and/or
the vboot recovery code.
When CONSOLE_CBMEM_DUMP_TO_UART is selected it will dump the entire
cbmem console to the UART whenever `vboot_reboot()` is called. We don't
incur any boot time penalty in the happy path, but still retain the
ability to access the logs when an error occurs.
The previous implementation was using a hard coded UART index and
`get_uart_baudrate` was always returning 0 since `CONFIG_TTYS0_BAUD`
wasn't defined. This change makes it so the UART console properties are
available when CONSOLE_CBMEM_DUMP_TO_UART is set. This results in the
following .config diff:
+CONFIG_UART_FOR_CONSOLE=0
+CONFIG_TTYS0_BASE=0x3f8
+CONFIG_TTYS0_LCS=3
+CONFIG_CONSOLE_SERIAL_115200=y
+CONFIG_TTYS0_BAUD=115200
This functionality is especially helpful on Guybrush. PSP Verstage is
run on S0i3 resume. Today, if there is an error, the cbmem console is
lost since it lives in the PSP SRAM.
BUG=b:213828947, b:215599230
TEST=Build non-serial guybrush FW and verify no serial output happens in
happy path. Inject a vboot error and perform an S0i3 suspend/resume.
Verify CBMEM console gets dumped to the correct UART.

Building libgfxinit with Debian’s toolchain – latest test with *gnat-11*

When running in verstage before bootblock, the PSP (ARM co-processor) is
running with limited SRAM. It needs to stash the verstage console data
internally until DRAM is brought up. Once DRAM is brought up the data is
stashed in a "transfer buffer" region. In the current design, we are
using the same region for the transfer buffer and the
preram_cbmem_console region. This has the following downsides:
1) The pre-x86 buffer needs to be large enough to hold all the
verstage, bootblock and romstage console logs.
2) On AMD platforms, the PSP verstage is signed. Changing the size of
preram_cbmem_console after the fact will result in a mismatch of the
transfer buffer between verstage and bootblock.
This CL adds a new method that allows SoC specific code to copy the
CBMEM console in the transfer buffer to the active CBMEM console.

This patch moves the CBFS file measurement when CONFIG_TPM_MEASURED_BOOT
is enabled from the lookup step into the code where a file is actually
loaded or mapped from flash. This has the advantage that CBFS routines
which just look up a file to inspect its metadata (e.g. cbfs_get_size())
do not cause the file to be measured twice. It also removes the existing
inefficiency that files are loaded twice when measurement is enabled
(once to measure and then again when they are used). When CBFS
verification is enabled and uses the same hash algorithm as the TPM, we
are even able to only hash the file a single time and use the result for
both purposes.

This patch adds a new ..._unverified_area_... group of functions to the
cbfs_map/_load/_alloc() APIs. These functions can be used to access
custom FMAP sections and are meant to replace the existing
cbfs_locate_file_in_region(). The name is intended to highlight that
accesses through this API will not be verified when CBFS_VERIFICATION is
enabled and should always be treated as if they may return malicious
data. (Due to laziness I'm not adding the combination of this API with
the ..._type_... variant at this point, since it seems very unlikely
that we'll ever have a use case for that. If we ever do, it should be
easy to add later.)

This patch adds cbfs_get_size() and cbfs_get_type() helper functions
(and _ro_ variations) to look up the size or type of a CBFS file without
loading it. Generally, use of these should be discouraged because that
tends to mean that the file needs to be looked up more than once, and
cbfs_alloc() or cbfs_type_load() are usually the more efficient
alternative... but sometimes they're unavoidable, so we might as well
offer them.
Also remove the <cbfs_private.h> header which had already become sort of
unnecessary with previous changes. cbfs_boot_lookup() is now exported in
<cbfs.h> for use in inlines, but should not be used directly by other
files (and is prefixed with an underscore to highlight that).

Now that CBFS has this functionality built in, we no longer need to
manually code it.
payload_preload used to use the payload_preload_cache region to store
the raw payload contents. This region was placed outside the firmware
reserved region, so it was available for use by the OS. This was
possible because the payload isn't loaded again on S3 resume.
cbfs_preload only uses the cbfs_cache region. This region must be
reserved because it gets used on the S3 resume path. Unfortunately this
means that cbfs_cache must be increased to hold the payload. Cezanne is
the only platform currently using payload_preload, and the size of
cbfs_cache has already been adjusted.
In the future we could look into adding an option to cbfs_preload that
would allow it to use a different memory pool for the cache allocation.

issue due to renaming of existing macros due to scoping the Memory
Type.
2. Use dedicated Memory Type and Module type for `Form Factor`
and `TypeDetail` conversion using `get_spd_info()` function.
3. Create a new API (convert_form_factor_to_module_type()) for
`Form Factor` to 'Module type' conversion as per `Memory Type`.
4. Add new argument as `Memory Type` to
smbios_form_factor_to_spd_mod_type() so that it can internally
call convert_form_factor_to_module_type() for `Module Type`
conversion.
5. Update `test_smbios_form_factor_to_spd_mod_type()` to

6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).

Currently, the MMCONF Kconfigs only support the Enhanced Configuration
Access mechanism (ECAM) method for accessing the PCI config address
space. Some platforms have a different way of mapping the PCI config
space to memory. This patch renames the following configs to
make it clear that these configs are ECAM-specific:
- NO_MMCONF_SUPPORT --> NO_ECAM_MMCONF_SUPPORT
- MMCONF_SUPPORT --> ECAM_MMCONF_SUPPORT
- MMCONF_BASE_ADDRESS --> ECAM_MMCONF_BASE_ADDRESS
- MMCONF_BUS_NUMBER --> ECAM_MMCONF_BUS_NUMBER
- MMCONF_LENGTH --> ECAM_MMCONF_LENGTH

This API will hide all the complexity of preloading a CBFS file. It
makes it so the callers simply specify the file to preload and CBFS
takes care of the rest. It will start a new thread to read the file into
the cbfs_cache. When the file is actually required (i.e., cbfs_load,
etc) it will wait for the preload thread to complete (if it hasn't
already) and perform verification/decompression using the preloaded
buffer. This design allows decompression/verification to happen in the
main BSP thread so that timestamps are correctly reflected.

CB:51638 separated Chrome OS NVS from global NVS by allocating it

information at boot time. Thus, location of CNVS needs to be shared in
coreboot tables for depthcharge to use.
This change adds a new coreboot table tag
`CB_TAG_ACPI_CNVS`/`CB_TAG_ACPI_CNVS`(0x41) which provides the
location of CNVS in CBMEM to payload (depthcharge).
Additionally, CB:51639 refactored device nvs(DNVS) and moved it to the
end of GNVS instead of the fixed offset 0x1000. DNVS is used on older
Intel platforms like baytrail, braswell and broadwell and depthcharge
fills this at boot time as well. Since DNVS is no longer used on any
new platforms, this information is not passed in coreboot
tables. Instead depthcharge is being updated to use statically defined
offsets for DNVS.

The `location` member of `struct boot_state_callback` is conditionally
guarded depending on `CONFIG(DEBUG_BOOT_STATE)` using preprocessor. It
is probably intended to save some space when the `location` strings do
not get printed. However, directly using the `location` member without
any guards will cause a compile-time error. Plus, preprocessor-guarded
code gets nasty really quickly.
In order to minimise preprocessor usage, introduce the `bscb_location`
inline helper function, which transforms the compile-time error into a
link-time error. It is then possible to substitute preprocessor guards
with an ordinary C `if` statement.

There are cases where the RTC_VRT bit in register D stays set after a
power failure while the real date and time registers can contain rubbish
values (can happen when RTC is not buffered). If we do not detect this
invalid date and/or time here and keep it, Linux will use these bad
values for the initial timekeeper init. This in turn can lead to dates
before 1970 in user land which can break a lot assumptions.
To fix this, check date and time sanity when the RTC is initialized and
reset the values if needed.

Over the last couple of years we have continuously added more and more
CBMEM init hooks related to different independent components. One
disadvantage of the API is that it can not model any dependencies
between the different hooks, and their order is essentially undefined
(based on link order). For most hooks this is not a problem, and in fact
it's probably not a bad thing to discourage implicit dependencies
between unrelated components like this... but one resource the
components obviously all share is CBMEM, and since many CBMEM init hooks
are used to create new CBMEM areas, the arbitrary order means that the
order of these areas becomes unpredictable.
Generally code using CBMEM should not care where exactly an area is
allocated, but one exception is the persistent CBMEM console which
relies (on a best effort basis) on always getting allocated at the same
address on every boot. This is, technically, a hack, but it's a pretty
harmless hack that has served us reasonably well so far and would be
difficult to realize in a more robust way (without adding a lot of new
infrastructure). Most of the time, coreboot will allocate the same CBMEM
areas in the same order with the same sizes on every boot, and this all
kinda works out (and since it's only a debug console, we don't need to
be afraid of the odd one-in-a-million edge case breaking it).
But one reproducible difference we can have between boots is the vboot
boot mode (e.g. normal vs. recovery boot), and we had just kinda gotten
lucky in the past that we didn't have differences in CBMEM allocations
in different boot modes. With the recent addition of the RW_MCACHE
(which does not get allocated in recovery mode), this is no longer true,
and as a result CBMEM consoles can no longer persist between normal and
recovery modes.
The somewhat kludgy but simple solution is to just create a new class of
specifically "early" CBMEM init hooks that will always run before all
the others. While arbitrarily partitioning hooks into "early" and "not
early" without any precise definition of what these things mean may seem
a bit haphazard, I think it will be good enough in practice for the very
few cases where this matters and beats building anything much more
complicated (FWIW Linux has been doing something similar for years with
device suspend/resume ordering). Since the current use case only relates
to CBMEM allocation ordering and you can only really be "first" if you
allocate in romstage, the "early" hook is only available in romstage for
now (could be expanded later if we find a use case for it).

returns false. When fw_config support is disabled, this function

fw_config is unprovisioned in the factory for the first boot. This is
the only case where fw_config is left unprovisioned. On first boot in
factory, fw_config gets correctly provisioned by the factory
toolkit. When fw_config is unprovisioned, it is not always possible to
make a guess which device to enable/disable since there can be certain
conflicting devices which can never be enabled at the same time. That
is the reason the original implementation of fw_config library kept
fw_config as 0 when it was unprovisioned.
CB:47956 ("fw_config: Use UNDEFINED_FW_CONFIG to mean unprovisioned")
added support for a special unprovisioned value to allow any callers
to identify this factory boot condition and take any appropriate
action required for this boot (Ideally, this would just involve
configuring any boot devices essential to getting to OS. All other
non-essential devices can be kept disabled until fw_config is properly
provisioned). However, CB:47956 missed handling the
`fw_config_probe()` function and resulted in silent change in behavior.
This change fixes the regression introduced by CB:47956 and returns
`false` in `fw_config_probe()` if fw_config is not provisioned yet.

The CBFS mcache size default was eyeballed to what should be "hopefully
enough" for most users, but some recent Chrome OS devices have already
hit the limit. Since most current (and probably all future) x86 chipsets
likely have the CAR space to spare, let's just double the size default
for all supporting chipsets right now so that we hopefully won't run
into these issues again any time soon.
The CBFS_MCACHE_RW_PERCENTAGE default for CHROMEOS was set to 25 under
the assumption that Chrome OS images have historically always had a lot
more files in their RO CBFS than the RW (because l10n assets were only
in RO). Unfortunately, this has recently changed with the introduction
of updateable assets. While hopefully not that many boards will need
these, the whole idea is that you won't know whether you need them yet
at the time the RO image is frozen, and mcache layout parameters cannot
be changed in an RW update. So better to use the normal 50/50 split on
Chrome OS devices going forward so we are prepared for the eventuality
of needing RW assets again.
The RW percentage should really also be menuconfig-controllable, because
this is something the user may want to change on the fly depending on
their payload requirements. Move the option to the vboot Kconfigs
because it also kinda belongs there anyway and this makes it fit in
better in menuconfig. (I haven't made the mcache size
menuconfig-controllable because if anyone needs to increase this, they
can just override the default in the chipset Kconfig for everyone using
that chipset, under the assumption that all boards of that chipset have
the same amount of available CAR space and there's no reason not to use
up the available space. This seems more in line with how this would work
on non-x86 platforms that define this directly in their memlayout.ld.)
Also add explicit warnings to both options that they mustn't be changed
in an RW update to an older RO image.

We had the addrspace_32bit rdev in prog_loaders.c for a while to help
represent memory ranges as an rdev, and we've found it useful for a
couple of things that have nothing to do with program loading. This
patch moves the concept straight into commonlib/region.c so it is no
longer anchored in such a weird place, and easier to use in unit tests.
Also expand the concept to the whole address space (there's no real need
to restrict it to 32 bits in 64-bit environments) and introduce an
rdev_chain_mem() helper function to make it a bit easier to use. Replace
some direct uses of struct mem_region_device with this new API where it
seems to make sense.

CBFS_VERIFICATION requires the CBFS metadata hash anchor to be linked
into an uncompressed stage, but for platforms using COMPRESS_BOOTBLOCK,
this is only the decompressor stage. The first CBFS accesses are made in
the bootblock stage after decompression, so if we want to make
CBFS_VERIFICATION work on those platforms, we have to pass the metadata
hash anchor from the decompressor into the bootblock. This patch does
just that. (Note that this relies on the decompressor data remaining
valid in memory for as long as the metadata hash anchor is needed. This
is always true even for OVERLAP_DECOMPRESSOR_ROMSTAGE() situations
because the FMAP and CBFS metadata necessarily need to have finished
verification before a new stage could be loaded.)

This patch adds file data hashing for CONFIG_CBFS_VERIFICATION. With
this, all CBFS accesses using the new CBFS APIs (cbfs_load/_map/_alloc
and variants) will be fully verified when verification is enabled. (Note
that some use of legacy APIs remains and thus the CBFS_VERIFICATION
feature is not fully finished.)

With the last external user to cbfs_load_and_decompress() gone, we can
stop exporting this function to the rest of coreboot and make it local
to cbfs.c. Also remove a couple of arguments that no longer really make
a difference and fold the stage-specific code for in-place LZ4
decompression into cbfs_prog_stage_load().

Right before CB:49334 was submitted, I changed the signature of
cbfs_allocator_t function pointers to include another argument passing
in the already loaded CBFS metadata (to allow for the rare edge case of
allocators needing to read CBFS attributes). This interface is not meant
to be able to modify the passed-in metadata, so to clarify that and
prevent potential errors, we should declare the argument const.

In pursuit of the goal of eliminating the proliferation of raw region
devices to represent CBFS files outside of the CBFS core code, this
patch removes the get_spd_cbfs_rdev() API and instead replaces it with
spd_cbfs_map() which will find and map the SPD file in one go and return
a pointer to the relevant section. (This makes it impossible to unmap
the mapping again, which all but one of the users didn't bother to do
anyway since the API is only used on platforms with memory-mapped
flash. Presumably this will stay that way in the future so this is not
something worth worrying about.)

In pursuit of the eventual goal of removing cbfs_boot_locate() (and
direct rdev access) from CBFS APIs, this patch replaces all remaining
"simple" uses of the function call that can easily be replaced by the
newer APIs (like cbfs_load() or cbfs_map()). Some cases of
cbfs_boot_locate() remain that will be more complicated to solve.

The CBFS stage header is part of the file data (not the header) from
CBFS's point of view, which is problematic for verification: in pre-RAM
environments, there's usually not enough scratch space in CBFS_CACHE to
load the full stage into memory, so it must be directly loaded into its
final destination. However, that destination is decided from reading the
stage header. There's no way we can verify the stage header without
loading the whole file and we can't load the file without trusting the
information in the stage header.
To solve this problem, this patch changes the CBFS stage format to move
the stage header out of the file contents and into a separate CBFS
attribute. Attributes are part of the metadata, so they have already
been verified before the file is loaded.
Since CBFS stages are generally only meant to be used by coreboot itself
and the coreboot build system builds cbfstool and all stages together in
one go, maintaining backwards-compatibility should not be necessary. An
older version of coreboot will build the old version of cbfstool and a
newer version of coreboot will build the new version of cbfstool before
using it to add stages to the final image, thus cbfstool and coreboot's
stage loader should stay in sync. This only causes problems when someone
stashes away a copy of cbfstool somewhere and later uses it to try to
extract stages from a coreboot image built from a different revision...
a debugging use-case that is hopefully rare enough that affected users
can manually deal with finding a matching version of cbfstool.
The SELF (payload) format, on the other hand, is designed to be used for
binaries outside of coreboot that may use independent build systems and
are more likely to be added with a potentially stale copy of cbfstool,
so it would be more problematic to make a similar change for SELFs. It
is not necessary for verification either, since they're usually only
used in post-RAM environments and selfload() already maps SELFs to
CBFS_CACHE before loading them to their final destination anyway (so
they can be hashed at that time).
