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.

The TPM2 specification allows defining NV ram spaces in a manner
that makes it impossible to remove the space until a certain PCR is in
a certain state.
This comes in handy when defining spaces for rollback counters: make
their removal depend on PCR0 being in the default state. Then extend
PCR0 to any value. This guarantees that the spaces can not be deleted.
Also, there is no need t create firmware and kernel rollback spaces
with different privileges: they both can be created with the same set of
properties, the firmware space could be locked by the RO firmware, and
the kernel space could be locked by the RW firmware thus providing
necessary privilege levels.
BRANCH=none
BUG=chrome-os-partner:50645, chrome-os-partner:55063
TEST=with the rest of the patches applied it is possible to boot into
Chrome OS maintaining two rollback counter spaces in the TPM NV
ram locked at different phases of the boot process.

The marshaling/unmarshaling code is using integer values to represent
room left in the buffer, to be able to communicate three conditions:
positive number means there is room left in the buffer, zero means
that the exact amount of data in the buffer was unmarshaled and
negative value means that the result of the operation did not fit into
the buffer.
The implementation is wrong though, as it compares directly signed and
unsigned values, which is illegal, as signed values get promoted to
unsigned by the compiler.
This patch changes the marshaling code to use size_t for the size, and
use zero as marshaling failure indication - after all the buffer where
the data is marshaled to should definitely be large enough, and it is
reasonable to expect at least some room left in it after marshaling.
The unmarshaling situation is different: we sure want to communicate
errors to the caller, but do not want to propagate error return values
through multiple layers. This patch keeps the size value in int, but
checks if it is negative separately, before comparing with positive
values.

TPM commands need to be serialized (marshaled) to be sent to the
device, and the responses need to be de-serialized (unmarshaled) to be
properly interpreted by upper layers.
This layer does not exist in TPM1.2 coreboot implementation, all TPM
commands used there were hardcoded as binary arrays. Availability of
the marshaling/unmarshaling layer makes it much easier to add new TPM
commands to the code.
Command and response structures used in these functions are defined in

This is the first approximation of implementing TPM2 support in
coreboot. It is very clearly incomplete, some of the larger missing
pieces being:
- PCR(s) modification
- protection NVRAM spaces from unauthorized deletion/modification.
- resume handling
- cr50 specific factory initialization
The existing TPM1.2 firmware API is being implemented for TPM2. Some
functions are not required at all, some do not map fully, but the API
is not yet being changed, many functions are just stubs.
An addition to the API is the new tlcl_define_space() function. It
abstracts TMP internals allowing the caller to specify the privilege
level of the space to be defined. Two privilege levels are defined,
higher for the RO firmware and lower for RW firmware, they determine
who can write into the spaces.

Add a new function "gpio_acpi_path()" that can be implemented by
SoC/board code to provide a mapping from a "gpio_t" pin to a
controller by returning the ACPI path for the controller that owns
this particular GPIO.
This is implemented separately from the "acpi_name" handler as many
SOCs do not have a specific device that handles GPIOs (or may have
many devices and the only way to know which is the opaque gpio_t)
and the current GPIO library does not have any association with the
device tree.
If not implemented (many SoCs do not implement the GPIO library
abstraction at all in coreboot) then the default handler will return
NULL and the caller knows it cannot determine this reliably.

timestamp_cache_get() would call timestamp_cache_init() whenever it
found a timestamp cache in the TIMESTAMP_CACHE_UNINITIALIZED state.
That means that timestamp_cache_get() will never reurn a cache in the
uninitialized state.
However, timestamp_init() checks against the uninitialized state, as
it does not expect timestamp_cache_get() to perform any initialization.
As a result, the conditional branch can never be reached.
Simply remove the timestamp_cache_init() call from timestamp_cache_get().

Extend the serial port description to include the input clock frequency
and a payload specific value.
Without the input frequency it is impossible for the payload to compute
the baud-rate divisor without making an assumption about the frequency.
This breaks down when the UART is able to support multiple input clock
frequencies.
Add the UART_PCI_ADDR Kconfig value to specify the unique PCI device
being used as the console UART. Specify this value as zero when the
UART is not on the PCI bus. Otherwise specify the device using bus,
device and function along with setting the valid bit.
Currently the only payload to consume these new fields is the EDK-II
CorebootPayloadPkg.
Testing on Galileo:
* Edit the src/mainboard/intel/galileo/Makefile.inc file:
* Add "select ADD_FSP_PDAT_FILE"
* Add "select ADD_FSP_RAW_BIN"
* Add "select ADD_RMU_FILE"
* Place the FSP.bin file in the location specified by CONFIG_FSP_FILE
* Place the pdat.bin files in the location specified by

* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate

* Testing is successful when CorebootPayloadPkg is able to properly
initialize the serial port without using built-in values.

Our EDID code had always been aligning the framebuffer's
bytes_per_line (and x_resolution dependent on that) to 64. It turns out
that this is a controller-dependent parameter that seems to only really
be necessary for Intel chipsets, and commit 6911219cc (edid: Add helper
function to calculate bits-per-pixel dependent values) probably actually
broke this for some other controllers by applying the alignment too
widely.
This patch makes it explicitly configurable and depends the default on
ARCH_X86 (which seems to be the simplest and least intrusive way to make
it fit most cases for now... boards where this doesn't apply can still
override it manually by calling edid_set_framebuffer_bits_per_pixel()
again).

A long time ago many Chrome OS boards had pages full of duplicated
boilerplate code for the fill_lb_gpios() function, and we spent a lot of
time bikeshedding a proper solution that passes a table of lb_gpio
structs which can be concisely written with a static struct initializer
in http://crosreview.com/234648. Unfortunately we never really finished
that patch and in the mean time a different solution using the
fill_lb_gpio() helper got standardized onto most boards.
Still, that solution is not quite as clean and concise as the one we had
already designed, and it also wasn't applied consistently to all recent
boards (causing more boards with bad code to get added afterwards). This
patch switches all boards newer than Link to the better solution and
also adds some nicer debug output for the GPIOs while I'm there.
If more boards need to be converted from fill_lb_gpio() to this model
later (e.g. from a branch), it's quite easy to do with:
s/fill_lb_gpio(gpio++,\n\?\s*\([^,]*\),\n\?\s*\([^,]*\),\n\?\s*\([^,]*\),\n\?\s*\([^,]*\));/\t{\1, \2, \4, \3},/

Coreboot and most payloads support three basic pixel widths for the
framebuffer. It assumes 32 by default, but several chipsets need to
override that value with whatever else they're supporting. Our struct
edid contains multiple convenience values that are directly derived from
this (and other properties), so changing the bits per pixel always
requires recalculating all those dependents in the chipset code. This
patch provides a small convenience wrapper that can be used to
consistently update the whole struct edid with a new pixel width
instead, so we no longer need to duplicate those calculations
everywhere.

Certain chipsets don't have a memory-mapped boot media
so their code execution for stages prior to DRAM initialization
is backed by SRAM or cache-as-ram. The postcar stage/phase
handles the cache-as-ram situation where in order to tear down
cache-as-ram one needs to be executing out of a backing
store that isn't transient. By current definition, cache-as-ram
is volatile and tearing it down leads to its contents disappearing.
Therefore provide a shim layer, postcar, that's loaded into
memory and executed which does 2 things:
1. Tears down cache-as-ram with a chipset helper function.
2. Loads and runs ramstage.
Because those 2 things are executed out of ram there's no issue
of the code's backing store while executing the code that
tears down cache-as-ram. The current implementation makes no
assumption regarding cacheability of the DRAM itself. If the
chipset code wishes to cache DRAM for loading of the postcar
stage/phase then it's also up to the chipset to handle any
coherency issues pertaining to cache-as-ram destruction.

This patch adds support for an alternative ternary number system in
which group of GPIOs can be interpreted. In this system, the digit
combinations that would form a binary number (i.e. that contain no 'Z'
state) are used to represent the lower values in the way they're used in
the normal binary system, and all the combinations that do contain a 'Z'
are used to represent values above those. We can use this for boards
that originally get strapped with binary board IDs but eventually
require more revisions than that representation allows. We can switch
their code to binary_first base3 and all old revisions with already
produced boards will still get read as the correct numbers.
Credit for the algorithm idea goes to Haran Talmon.

There was no 'early' call into the SoC code prior to console
getting initialized. Not having this enforces the mainboard to
drive the setup of the console which typically just ends up
calling into the SoC code. Provide a SoC early init call
to handle this without having to duplicate the same code
in mainboards utilizing the same SoC.

This patch ports the LZ4 decompression code that debuted in libpayload
last year to coreboot for use in CBFS stages (upgrading the base
algorithm to LZ4's dev branch to access the new in-place decompression
checks). This is especially useful for pre-RAM stages in constrained
SRAM-based systems, which previously could not be compressed due to
the size requirements of the LZMA scratchpad and bounce buffer. The
LZ4 algorithm offers a very lean decompressor function and in-place
decompression support to achieve roughly the same boot speed gains
(trading compression ratio for decompression time) with nearly no
memory overhead.
For now we only activate it for the stages that had previously not been
compressed at all on non-XIP (read: non-x86) boards. In the future we
may also consider replacing LZMA completely for certain boards, since
which algorithm wins out on boot speed depends on board-specific
parameters (architecture, processor speed, SPI transfer rate, etc.).
BRANCH=None
BUG=None
TEST=Built and booted Oak, Jerry, Nyan and Falco. Measured boot time on
Oak to be about ~20ms faster (cutting load times for affected stages
almost in half).

We've had a second version of ulzma() that would check the input and
output buffer sizes in libpayload for a while now. Since it's generally
never a bad idea to double-check for overruns, let's port it to coreboot
and use it where applicable. (This requires a small fix in the four byte
at a time read optimization we only have in coreboot, since it made the
stream counter hit the end a little earlier than the algorithm liked and
could trigger an assertion.)

previous mappings are still in use).

sitting in each vboot RW slot. Remove the support for the
stand-alone assets and always use CBFS accesses as the
way to retrieve data.
This is implemented by adding a cbfs_locator object which
is queried for locating the current CBFS. Additionally, it
is also signalled prior to when a program is about to be
loaded by coreboot for the subsequent stage/payload. This
provides the same opportunity as previous for vboot to
hook in and perform its logic.

Most devices do not use SPI before they initialize CBMEM. This change
initializes spi_flash in the CBMEM_INIT_HOOK to initialize the postram
cbfs cache so it is not overwritten when boot_device_init is called
later.
BUG=chromium:210230
BRANCH=none
TEST=confirm that the first cbfs access can occur before RAM initialized
and after on panther and jerry.

Currently the CBFS mmap cannot be accessed at the beginning of romstage
because it waits until DRAM is initialized. This change first loads CBFS
into SRAM and then switches to using DRAM as the backing once it is
initialized.

If the timestamp table gets corrupted (separate issue), the
timestamp_sync_cache_to_cbmem() function may add a large number of bogus
timestamp entries.
This causes a flood of "ERROR: Timestamp table full". With logs going
to a serial console, this renders the system essentially unbootable.
There really isn't a need to log that more than once, so log it when the
last slot in the timestamp table is filled.

hexdump currently rounds up length to a multiple of 16.
So, hexdump(ptr, 12) prints 16 hex digits, including 4 garbage bytes.
That isn't desirable and is easy to fix.

There are few drawbacks reading VPD from SPI flash in user land, including
"lack of firmware level authority" and "slow reading speed".
Since for many platforms we are already reading VPD in firmware (for
example MAC and serial number), caching the VPD data in CBMEM should
will speed up and simplify user land VPD processing without adding
performance cost.
A new CBMEM ID is added: CBMEM_ID_VPD, referring to a structure containing
raw Google VPD 2.0 structure and can be found by the new LB_TAG_VPD in
Coreboot tables.

The EDID parsing code continued to update _some_ fields of the output
edid but not others if "did_detailed_timing" was already set. It also
then went on to print out this halfway mix of modes each time, despite
the fact that it didn't really update everything.
Let's fix that. We'll reduce code changes by using a temporary copy of
data in detailed_block() and then we'll copy it back if we decide we
should update.
