60293e9b1f lib/ramtest.c: Update ram failure post code
coreboot already has a ram failure post code defined, but the ram test
functions weren't using it, and were using 0xea instead.
This changes those failures to display 0xe3, the value defined in
post_codes.h by POST_RAM_FAILURE.

967a76bd81 vboot: Add VBOOT_CBFS_INTEGRATION support
This patch introduces support signing and verification of firmware
slots using CBFS metadata hash verification method for faster initial
verification. To have complete verification, CBFS_VERIFICATION should
also be enabled, as metadata hash covers only files metadata, not their
contents.

This patch also adapts mainboards and SoCs to new vboot reset
requirements.

9948c521a6 lib/coreboot_table: Simplify API to set up lb_serial
Instead of having callbacks into serial console code to set up the
coreboot table have the coreboot table code call IP specific code to get
serial information. This makes it easier to reuse the information as the
return value can be used in a different context (e.g. when filling in a
FDT).

This also removes boilerplate code to set up lb_console entries by
setting entry based on the type in struct lb_uart.

d96ca24652 cbfs/vboot: Adapt to new vb2_digest API
CL:3825558 changes all vb2_digest and vb2_hash functions to take a new
hwcrypto_allowed argument, to potentially let them try to call the
vb2ex_hwcrypto API for hash calculation. This change will open hardware
crypto acceleration up to all hash calculations in coreboot (most
notably CBFS verification). As part of this change, the
vb2_digest_buffer() function has been removed, so replace existing
instances in coreboot with the newer vb2_hash_calculate() API.

Due to the circular dependency of these changes with vboot, this patch
also needs to update the vboot submodule:

coreboot's heap manager also is quite limited in what it will

be full at some point, breaking the smihandler.

This also reduces the ramstage by 448 bytes on google/vilboz.

2efd8315f2 lib/Makefile.inc: Add cbfs header pointer on !BOOTBLOCK_IN_CBFS
On some x86 targets it the bootblock is loaded via a different
mechanism, like via the AMD PSP or Intel IFWI. Some payloads need that
pointer so add it to cbfs.

Note that on Intel APL this file is not used, which is why the
bootblock still needs to contain the pointer in the ARCH_X86 part.
It is not worth it to add logic to specifically deal with APL as this is
a legacy feature anyway.

For AMD non-car platform this fixes cbfs access in SeaBIOS.

There are efforts to have bootflows that do not follow a traditional
bootblock-romstage-postcar-ramstage model. As part of that CBMEM
initialisation hooks will need to move from romstage to bootblock.

The interface towards platforms and drivers will change to use one of
CBMEM_CREATION_HOOK() or CBMEM_READY_HOOK(). Former will only be called
in the first stage with CBMEM available.

75226bb879 Makefile.inc: Generate master header and pointer as C structs
The makefiles don't like cbfs file names with spaces in them so update
the file name with '_' instead of spaces. To keep the master header at
the top of cbfs, add a placeholder.

This removes the need to handle the cbfs master header in cbfstool.
This functionality will be dropped in a later CL.

On x86 reserve some space in the linker script to add the pointer.
On non-x86 generate a pointer inside a C struct file.

As a bonus this would actually fix the master header pointer mechanism
on Intel/APL as only the bootblock inside IFWI gets memory mapped.

TESTED on thinkpad X201: SeaBIOS correctly finds the cbfs master
header.

Another reason to do this is the following:
On some platforms that start in dram it makes little sense to have
separate stages. To reduce the complexity we want to call the ramstage
main function instead of loading a full stage. To make this scheme
more maintainable it makes sense to move out as much functionality
from the 'main' function as possible.

 2. Most of allocated memory is not freed.
 3. Implementation of free() does something only for one last malloc'ed

c5160986cf cpu/x86/smm,lib/cbmem_console: Enable CBMEMC when using DEBUG_SMI
This change will allow the SMI handler to write to the cbmem console
buffer. Normally SMIs can only be debugged using some kind of serial
port (UART). By storing the SMI logs into cbmem we can debug SMIs using
`cbmem -1`. Now that these logs are available to the OS we could also
verify there were no errors in the SMI handler.

Since SMM can write to all of DRAM, we can't trust any pointers
provided by cbmem after the OS has booted. For this reason we store the
cbmem console pointer as part of the SMM runtime parameters. The cbmem
console is implemented as a circular buffer so it will never write
outside of this area.

984d03c492 console: Add loglevel marker codes to stored consoles
In order to provide the same loglevel prefixes and highlighting that
were recently introduced for "interactive" consoles (e.g. UART) to
"stored" consoles (e.g. CBMEM) but minimize the amont of extra storage
space wasted on this info, this patch will write a 1-byte control
character marker indicating the loglevel to the start of every line
logged in those consoles. The `cbmem` utility will then interpret those
markers and translate them back into loglevel prefixes and escape
sequences as needed.

Since coreboot and userspace log readers aren't always in sync,
occasionally an older reader may come across these markers and not know
how to interpret them... but that should usually be fine, as the range
chosen contains non-printable ASCII characters that normally have no
effect on the terminal. At worst the outdated reader would display one
garbled character at the start of every line which isn't that bad.
(Older versions of the `cbmem` utility will translate non-printable
characters into `?` question marks.)

6ec3dd2e5c lib/cbmem_console,console: Resurrect CONSOLE_CBMEM_DUMP_TO_UART
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.

1e1aa0ca4d lib/cbmem_console: Add cbmemc_copy_in function
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.

7e7cc1a8c9 cbfs | tspi: Join hash calculation for verification and measurement
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.

05714ccab7 cbfs: Add unverified_area APIs
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.)

(Also remove the 'inline' from cbfs_file_hash_mismatch(). I'm not sure
why I put it there in the first place, probably a bad copy&paste.)

57d4bc63f0 cbfs: Add helper functions to look up size and type of a file
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).

571e7f02de lib/prog_loaders, soc/amd/: Make payload_preload use cbfs_preload
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.

6de8b42482 arch/x86: Refactor the SMBIOS type 17 write function
List of changes:
1. Create Module Type macros as per Memory Type
(i.e. DDR2/DDR3/DDR4/DDR5/LPDDR4/LPDDR5) and fix compilation
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
accommodate different memory types.
6. Skip fixed module type to form factor conversion using DDR2 SPD4
specification (inside dimm_info_fill()).

Refer to datasheet SPD4.1.2.M-1 for LPDDRx and SPD4.1.2.L-3 for DDRx.

4cfb862fb2 lib/cbfs: Add cbfs_preload()
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.
