96ed92d49d boardid: Add helpers to read sku_id strapping into coreboot tables
On many recent Chrome OS boards, the desire to unite more configurations
under the same image has led to the need of a "SKU ID" that identifies
different configurations of the same board (e.g. with certain optional
components stuffed or not stuffed, or replaced with a comparable
component). This is markedly different from the existing "board ID",
because that is reserved to count "revisions" -- changes made to the
same configuration over time during the development process. This patch
adds support to have a mainboard define this SKU ID and pass it through
the coreboot table like we already have for board IDs.

4ec3d9d69e boardid: Switch from Kconfig to weak functions
This patch switches the board_id and ram_code helper framework to use
weak functions rather than Kconfigs to determine whether the board
supplies these IDs. This cuts down on the amount of boilerplate Kconfigs
many boards have to set and also gives them more flexibility, such as
being able to determine at runtime whether a given ID is present.

e2f17f782f boardid: Minor clean up and standardization
Merge the different coreboot table strapping ID structures into one
because they're really just all the same, and I want to add more. Make
the signature of the board_id() function return a uint32_t because
that's also what goes in the coreboot table. Add a printk to the generic
code handling strapping IDs in ramstage so that not every individual
mainboard implementation needs its own print. (In turn, remove one such
print from fsp1_1 code because it's in the way of my next patch.)

ec477346bf Kconfig: Remove BOARD_ID_MANUAL option
The BOARD_ID_MANUAL and BOARD_ID_STRING options were introduced for the
Urara board which is now long dead, and have never been used anywhere
else. They were trying to do something that we usually handle with a
separate SKU ID these days, whereas BOARD_ID is supposed to be reserved
for different revisions of the same board/SKU. Get rid of it to make
further refactoring of other options easier.

Also shove some stuff back into the Urara mainboard that should've never
crept into generic headers.

08f93599a9 cr50: process uninitialized values gracefully
The vboot code tries reading rollback protection indices from the TPM,
and if the attempt to read returns TPM_E_BADINDEX, it decides that the
TPM has not yet been initialized for the Chromebook use, and needs to
be taken through the factory initialization sequence.

TPM_E_BADINDEX is an internal representation of the TPM error 0x28b,
generated on attempts to read a non existing NVMEM space.

If the space exists, but has never been written the TPM returns error
0x14a. This condition (the space exists but not written) could happen
if the previous factory initialization attempt was interrupted right
after the space was created.

Let's map this error to the same internal representation
(TPM_E_BADINDEX) so that the Chrome OS device could recover when this
condition occurs.

BRANCH=reef, gru

01f9aa5e54 Consolidate reset API, add generic reset_prepare mechanism
There are many good reasons why we may want to run some sort of generic
callback before we're executing a reset. Unfortunateley, that is really
hard right now: code that wants to reset simply calls the hard_reset()
function (or one of its ill-differentiated cousins) which is directly
implemented by a myriad of different mainboards, northbridges, SoCs,
etc. More recent x86 SoCs have tried to solve the problem in their own
little corner of soc/intel/common, but it's really something that would
benefit all of coreboot.

This patch expands the concept onto all boards: hard_reset() and friends
get implemented in a generic location where they can run hooks before
calling the platform-specific implementation that is now called
do_hard_reset(). The existing Intel reset_prepare() gets generalized as
soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now
easily be added later if necessary). We will also use this central point
to ensure all platforms flush their cache before reset, which is
generally useful for all cases where we're trying to persist information
in RAM across reboots (like the new persistent CBMEM console does).

Also remove cpu_reset() completely since it's not used anywhere and
doesn't seem very useful compared to the others.

d906bb68c3 cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logs
The 'cbmem -1' flag that cuts off console output before the last boot
will ignore content from earlier stages if it was truncated due to lack
of pre-CBMEM console space. This patch makes the "log truncated" message
more specific and adds it as an additional cut-off marker to 'cbmem -1'
to counteract that problem.

Also raise the log level of the coreboot banner one step to BIOS_NOTICE
to make it more likely to be included in the output for 'cbmem -1' to
find. (I believe NOTICE is reasonable but I wouldn't want to go as far
as WARN which should be reserved for actual problems. Of course this is
not ideal, but then again, our whole log-level system really isn't... it
would be better if we could make it always print a banner to the CBMEM
console without affecting the UART at the same time, but that would
require a larger amount of work.)

d67c6876b5 Turn CBMEM console into a ring buffer that can persist across reboots
This patch allows the CBMEM console to persist across reboots, which
should greatly help post factum debugging of issues involving multiple
reboots. In order to prevent the console from filling up, it will
instead operate as a ring buffer that continues to evict the oldest
lines once full. (This means that if even a single boot doesn't fit into
the buffer, we will now drop the oldest lines whereas previous code
would've dropped the newest lines instead.)

The console control structure is modified in a sorta
backwards-compatible way, so that new readers can continue to work with
old console buffers and vice versa. When an old reader reads a new
buffer that has already once overflowed (i.e. is operating in true ring
buffer mode) it will print lines out of order, but it will at least
still print out the whole console content and not do any illegal memory
accesses (assuming it correctly implemented cursor overflow as it was
already possible before this patch).

491c5b60 (src/lib: Move assignment out of if condition)
which was reviewed in gerrit at https://review.coreboot.org/18761 and it
prevents coreboot from building when CONFIG_BOOTSPLASH is set.

e91d170d21 Remove libverstage as separate library and source file class
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are
linked directly into the bootblock or the romstage. However, they're
still compiled with a separate "libverstage" source file class, linked
into an intermediate library and then linked into the final destination
stage.

There is no obvious benefit to doing it this way and it's unclear why it
was chosen in the first place... there are, however, obvious
disadvantages: it can result in code that is used by both libverstage
and the host stage to occur twice in the output binary. It also means
that libverstage files have their separate compiler flags that are not
necessarily aligned with the host stage, which can lead to weird effects
like <rules.h> macros not being set the way you would expect. In fact,
VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86
because their libverstage code that gets compiled into the romstage sets
ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to
run pre-migration.

This patch resolves these problems by removing the separate library.
There is no more difference between the 'verstage' and 'libverstage'
classes, and the source files added to them are just treated the same
way a bootblock or romstage source files in configurations where the
verstage is linked into either of these respective stages (allowing for
the normal object code deduplication and causing those files to be
compiled with the same flags as the host stage's files).

Tested this whole series by booting a Kevin, an Elm (both with and
without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

58c3938705 vboot: Move remaining features out of vendorcode/google/chromeos
This patch attempts to finish the separation between CONFIG_VBOOT and
CONFIG_CHROMEOS by moving the remaining options and code (including
image generation code for things like FWID and GBB flags, which are
intrinsic to vboot itself) from src/vendorcode/google/chromeos to
src/vboot. Also taking this opportunity to namespace all VBOOT Kconfig
options, and clean up menuconfig visibility for them (i.e. some options
were visible even though they were tied to the hardware while others
were invisible even though it might make sense to change them).

021ec2819b cr50: add unmarshaling of vendor commands and process 'enable_update'
The upcoming Cr50 firmware changes will require the AP to enable the
previously downloaded Cr50 firmware update(s).

A new vendor command (TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for
that. The command accepts one parameter - a timeout value in range of
0 to 1000 ms.

When processing the command the Cr50 checks if the alternative RO or
RW image(s) need to be enabled, and if so - enables them and returns
to the host the number of enabled headers.

If the vendor command requested a non-zero timeout, the Cr50 starts
a timer to trigger system reboot after the requested timeout expires.

The host acts on the number of enabled headers - if the number is
nonzero, the host prepares the device to be reset and waits for the
Cr50 to reboot the device after timeout expires.

This patch also adds more formal vendor command
marshaling/unmarshaling to make future additions easier.

BRANCH=gru,reef
BUG=b:35580805
TEST=with the actual user of this code in the next patch verified that

eeb77379e0 vboot/tpm2: enable nvmem commits on cr50 when writing firmware secdata
cr50 by default delays nvmem commits internally from the point of
reset to accumulate change state. However, the factory process can
put a board into dev mode through the recovery screen. This state
is stored in the TPM's nvmem space. When the factory process is
complete a disable_dev_request and battery_cutoff_request is performed.
This leads to disabling the dev mode in TPM, but the battery is
subsequently cut off so the nvmem contents never stick. Therefore,
whenever antirollback_write_space_firmware() is called we know there
was a change in secdata so request cr50 to immediately enable nvmem
commits going forward. This allows state changes to happen immediately.

The fallout from this is that when secdata is changed that current
boot will take longer because every transaction that writes to TPM
nvmem space will perform a write synchronously. All subsequent boots
do not have that effect.

It should also be noted that this approach to the implementation is
a pretty severe layering violation. However, the current TPM APIs
don't lend themselves well to extending commands or re-using code
outside of the current routines which inherently assume all knowledge
of every command (in conflict with vendor commands since those are
vendor-specific by definition).

that function is reponsible for bootstrapping the cmos post register
contents. Without this function being called none of the cmos post
functionality works correctly. Therefore, add a call to lib/bootblock.c
which the C_ENVIRONMENT_BOOTBLOCK SoCs use.

16bd2676ce bootstate: add arch specific hook at coreboot exit
The bootstate machine allows one to schedule work at the
boundaries of each state. However, there are no priorities by
design. As such if there are things that need to be performed
that are interdependent between callbacks there's no way to
do that aside from explicitly putting the call in one of the
callbacks.

This situation arises around BS_OS_RESUME, BS_PAYLOAD_LOAD,
and BS_PAYLOAD_BOOT as those are the states where coreboot is
about to exit. As such, provide an architecture specific hook
at these key places so that one is guaranteed any work done
in arch_bootstate_coreboot_exit() is after all callbacks in
the state machine.

289ee8f0e9 lib/tpm2: do not create all NVRAM spaces with the same set of attributes
The TPM spaces created by the RO need to have different attributes
depending on the space's use. The firmware rollback counter and MRC
hash spaces are created by the RO code and need to be protected at the
highest level: it should be impossible to delete or modify the space
once the RO exits, and it is how it is done before this patch.

The rest of the spaces should be possible to modify or recreate even
after the RO exits. Let's use different set of NVRAM space attributes
to achieve that, and set the 'pcr0 unchanged' policy only for the
firmware counter and MRC cache spaces.

The definitions of the attributes can be found in "Trusted Platform
Module Library Part 2: Structures", Revision 01.16, section "13.2
TPMA_NV (NV Index Attributes)."

cc3365a039 TPM2: Fill in empty tlcl_resume function in TPM2 tlcl
On resume, TPM2_Starup(STATE) command needs to be sent to the TPM. This
ensures that TPM restores the state saved at last Shutdown(STATE).

Since tlcl_resume and tlcl_startup both use the same sequence for

that can be used by both.

1e9a914207 arch/x86,lib: make cbmem console work in postcar stage
Implement postcar stage cbmem console support. The postcar stage
is more like ramstage in that RAM is already up. Therefore, in
order to make the cbmem console reinit flow work one needs the cbmem
init hook infrastructure in place and the cbmem recovery called.
This call is added to x86/postcar.c to achieve that. Additionally,
one needs to provide postcar stage cbmem init hook callbacks for
the cbmem console library to use. A few other places need to
become postcar stage aware so that the code paths are taken.
Lastly, since postcar is backed by ram indicate that to the
cbmem backing store.

3c814b2e2b cbmem: Always maintain backing store struct in a global on non-x86
The current CBMEM code contains an optimization that maintains the
structure with information about the CBMEM backing store in a global
variable, so that we don't have to recover it from cbmem_top() again
every single time we access CBMEM. However, due to the problems with
using globals in x86 romstage, this optimization has only been enabled
in ramstage.

However, all non-x86 platforms are SRAM-based (at least for now) and
can use globals perfectly fine in earlier stages. Therefore, this patch
extends the optimization on those platforms to all stages. This also
allows us to remove the requirement that cbmem_top() needs to return
NULL before its backing store has been initialized from those boards,
since the CBMEM code can now keep track of whether it has been
initialized by itself.

f975e55dcd cbfs: Add "struct" file type and associated helpers
This patch adds functionality to compile a C data structure into a raw
binary file, add it to CBFS and allow coreboot to load it at runtime.
This is useful in all cases where we need to be able to have several
larger data sets available in an image, but will only require a small
subset of them at boot (a classic example would be DRAM parameters) or
only require it in certain boot modes. This allows us to load less data
from flash and increase boot speed compared to solutions that compile
all data sets into a stage.

Each structure has to be defined in a separate .c file which contains no
functions and only a single global variable. The data type must be
serialization safe (composed of only fixed-width types, paying attention
to padding). It must be added to CBFS in a Makefile with the 'struct'
file processor.

85b1aadcc1 memlayout: Ensure TIMESTAMP() region is big enough to avoid BUG()
The timestamp code asserts that the _timestamp region (allocated in
memlayout for pre-RAM stages) is large enough for the assumptions it
makes. This is good, except that we often initialize timestamps
extremely early in the bootblock, even before console output. Debugging
a BUG() that hits before console_init() is no fun.

This patch adds a link-time assertion for the size of the _timestamp
region in memlayout to prevent people from accidentally running into
this issue.

The spi_flash_probe() routine was setting a global varible
unconditonally regardless if the probe was for the boot device
or even if the boot devcie was flash. Moreover, there's no need
to report the SPI information if the boot device isn't even SPI.

Lastly, it's possible that the boot device is a SPI flash, but
the platform may never probe (selecting SPI_FLASH) for the
actual device connected. In that situation don't fill anything
in as no correct information is known.

dcbccd6a1e lib/boot_device: add RW boot device construct
The current boot device usage assumes read-only semantics to

boot device a device-specific API is invoked such as SPI flash.
Instead, provide a mechanism to retrieve an object that can
be used to perform writes to the boot device. On systems where
the implementations are symmetric these devices can be treated
one-in-the-same. However, for x86 systems with memory mapped SPI
the read-only boot device provides different operations.

The common boot device spi implementation is very much

it correctly depends on BOOT_DEVICE_SPI_FLASH. Additionally
that allows the auto-selection of SPI_FLASH by a platform
selecting COMMON_CBFS_SPI_WRAPPER which allows for culling
of SPI_FLASH selections everywhere.

The tpm2_marshal_command() function returns a negative value on error,
so we must use a signed type for the return value.

f5ef699f40 tpm2: implement and use pcr_extend command
TPM PCRs are used in Chrome OS for two purposes: to communicate
crucial information from RO firmware and to protect FW and kernel
rollback counters from being deleted.

As implemented in a TPM1 compatible way, the PCR extension command
requires a prebuilt digest to calculate a new PCR value.

TPM2 specification introduces a PCR_Event command, where the TPM
itself calculates the digest of an arbitrary length string, and then
uses the calculated digest for PCR extension. PCR_Event could be a
better option for Chrome OS, this needs to be investigated separately.

BRANCH=none
BUG=chrome-os-partner:50645
TEST=verified that the two PCRs are successfully extended before the
     RW firmware is called.
