Add a function for an SOC to define that will allow it to map the
SOC-specific gpio_t value into an appropriate ACPI pin. The exact
behavior depends on the GPIO implementation in the SOC, but it can
be used to provide a pin number that is relative to the community or
bank that a GPIO resides in.

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.

string and decode up to len bytes of data from it.
This can be used for turning MAC addresses or UUID strings into binary

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
CONFIG_FSP_PDAT_FILE
* Place the rmu.bin file in the location specified by CONFIG_RMU_FILE
* Build EDK2 CorebootPayloadPkg/CorebootPayloadPkgIa32.dsc to generate
UEFIPAYLOAD.fd
* Testing is successful when CorebootPayloadPkg is able to properly
initialize the serial port without using built-in values.

Before multi-CBFS support was added, x86 platforms cached their
ramstage in TSEG so that it could be re-used on the resume
path. However, more resources/assets are being put in cbfs that are
utilized during ramstage. Just caching ramstage does not mean that
correct cbfs region is used for all the data. Thus, provide an option
to allow platforms to skip caching any component for resume.

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.

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.
BRANCH=None
BUG=None
TEST=Stubbed out the actual GPIO reading and simulated all combinations
of 4 ternary digits for both number systems.

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.).

previous mappings are still in use).

Mediatek's bootblock needs mdelay, which depends on a udelay
implementation. Compiling the file for bootblock poses no harm:
Either udelay exists (in which case mdelay is usable) or it doesn't in
which case we see exactly the same kind of build time error (just with
udelay instead of mdelay).

This causes a flood of "ERROR: Timestamp table full". With logs going

The hardcoded clock value for 640x480 was 25.175 MHz. That's a valid
clock to use, but is quite hard to make a non-jittery clock from PLLs.
It's much easier to make 25.200 MHz, so let's do that.
The difference between the two modes is 59.9 Hz vs. 60 Hz and it seems
better to make a non-jittery 60 Hz rather than a very jittery 59.9 Hz.

When we first added ARM support to coreboot, it was clear that the
bootblock would need to do vastly different tasks than on x86, so we
moved its main logic under arch/. Now that we have several more
architectures, it turns out (as with so many things lately) that x86 is
really the odd one out, and all the others are trying to do pretty much
the same thing. This has already caused maintenance issues as the ARM32
bootblock developed and less-mature architectures were left behind with
old cruft.
This patch tries to address that problem by centralizing that logic
under lib/ for use by all architectures/SoCs that don't explicitly
opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option).
This works great out of the box for ARM32 and ARM64. It could probably
be easily applied to MIPS and RISCV as well, but I don't have any of
those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and
leave that for later cleanup.

Per IRC and Gerrit discussion, the normal / fallback
selector code is a rather weak spot in coreboot, and
did not function correctly for certain use cases.
Rework the selector to more clearly indicate proper
operation, and also remove dead code. Also tentatively
abandon use of RTC bit 385; a follow-up patch will
remove said bit from all affected mainboards.
The correct operation of the fallback code selector
approximates that of a power line recloser, with
a user option to attempt normal boot that can be
cleared by firmware, but never set by firmware.
Additionally, if cleared by user, the fallback
path should always be used on the next reboot.

This reverts commit e6606518243d9beda31693d40493b5f7a1a3e2e0.
After some discussion on IRC we decided to revert it as libpayload can
only read the copy that was removed (and other users like nvramtool can
only read the other copy). So we need both copies at this time.

Commit dbeedbef (arch/x86/bootblock: Link in object files selected with
bootblock-y) breaks building of x86 boards with
`CONFIG_EARLY_CBMEM_INIT` *not* selected but CBMEM time stamp collection
enabled.
Aaron Durbin explained as below [1] and provided this patch to fix it.
> That change actually processes bootblock-objs where before it never did
> such a thing. I'm sure this isn’t the only issue lurking. bootblock on
> x86 implied romcc and thus all the bootblock-y += rules that other
> architectures use worked, but now all the implied assumptions are no
> longer true on x86.
>
> timestamp stuff on x86 !CONFIG_EARLY_CBMEM_INIT is the issue you're
> seeing. In order to compile timestamp.c for bootblock under these
> conditions will mean there needs to be some more Makefile guarding.

To support x86 verstage one needs a working buffer for
vboot. That buffer resides in the cache-as-ram region
which persists across verstage and romstage. The current
assumption is that verstage brings cache-as-ram up
and romstage tears cache-as-ram down. The timestamp,
cbmem console, and the vboot work buffer are persistent
through in both romstage and verstage. The vboot
work buffer as well as the cbmem console are permanently
destroyed once cache-as-ram is torn down. The timestamp
region is migrated. When verstage is enabled the assumption
is that _start is the romstage entry point. It's currently
expected that the chipset provides the entry point to
romstage when verstage is employed. Also, the car_var_*()
APIs use direct access when in verstage since its expected
verstage does not tear down cache-as-ram. Lastly, supporting
files were added to verstage-y such that an x86 verstage
will build and link.

On x86 the early stages are currently execute-in-place which
means they live in the memory-mapped spi flash. However, when
loading romstage from verstage the romstage is
execute-in-place so it's unnecessary to write over a read-only
media -- not to mention writing to read-only memory is wrong
to begin with.

BRANCH=None
TEST=Built and booted glados. Noted reduction of 20ms when

The conditions in cbmem console for supporting verstage
were implicitly utilizing CONFIG_BOOTBLOCK_CONSOLE to handle
the cbmem console enablement. Fix it so verstage is a first
class citizen for deciding actions pertaining to cbmem console.
