Aaron Durbin 044fb53a2e lib/selfboot: clear BSS segments
For some reason the self loader wasn't clearing segments
marked as BSS type. Other segments which weren't fully
written by the file-backed content were being cleared up
to the indicated memsize. Treat segments marked BSS
similarly by clearing their content.

Vadim Bendebury 627afc2685 tpm2: add marshaling/unmarshaling layer
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
Parts 2 and 3 of the TCG issued document

Vadim Bendebury 245d4577d5 tpm2: implement tlcl layer
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.

Duncan Laurie 3a39f44fc4 gpio: Add a function to map GPIO to ACPI path
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.

Alexandru Gagniuc 63e7b5b8a7 lib/timestamp: Do not initialize cache in timestamp_cache_get()
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().

Lee Leahy f92a98c56e coreboot_tables: Extend serial port description
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.

Julius Werner 2b6db9738e edid: Make framebuffer row alignment configurable
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).

Julius Werner c445b4fc77 chromeos: Simplify fill_lb_gpios even further
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},/

Julius Werner 6911219ccc edid: Add helper function to calculate bits-per-pixel dependent values
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.

BUG=None
TEST=Booted Oak in all three pixel widths (which it conveniently all
supports), confirmed that images looked good.

Aaron Durbin 7f8afe0631 arch/x86: introduce postcar stage/phase
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.

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

Julius Werner 09f2921b5d cbfs: Add LZ4 in-place decompression support for pre-RAM stages
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

Duncan Laurie bc2c0a325a FMAP: Clean up debug output
Reduce the debug output from FMAP lookups.  When we had one or
two FMAP lookups in a boot this was not a big deal, but now that
we do many lookups it is a lot of unnecessary output duplication.

This change reduces these 3 lines:

FMAP: area VBLOCK_A found
FMAP:   offset: 200000
FMAP:   size:   65536 bytes

To just one line:

FMAP: area VBLOCK_A found @ 200000 (65536 bytes)

And makes the header output only print once:

FMAP: Found "FMAP" version 1.0 at c10000.
FMAP: base = 0 size = 1000000 #areas = 29

Julius Werner a25b5d257d lzma: Port size-checking ulzman() version to coreboot
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.)

commit a8aef3ac (cbfs_spi: Initialize spi_flash when initializing

CBFS_CACHE() memlayout macro break when used in conjunction with

postram_cbfs_cache region). This patch fixes the problem by making all
three region names always available for both the unified and split
macros in every stage (and adds code to ensure we don't reinitialize
the same buffer again in romstage, which might be a bad idea if
previous mappings are still in use).

Most devices do not use SPI before they initialize CBMEM. This change

cbfs cache so it is not overwritten when boot_device_init is called
later.

Ben Gardner f5fd4c99d5 lib/timestamp.c: only log "Timestamp table full" once
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.

"lack of firmware level authority" and "slow reading speed".

Douglas Anderson bca67fb7dc edid: Don't half parse (and wrongly print) more detailed timings
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.

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.

Julius Werner 86fc11d0c9 arm/arm64: Generalize bootblock C entry point
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.

Timothy Pearson 3bfd7cc61e drivers/pc80: Rework normal / fallback selector code
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.

Aaron Durbin 75c51d9af1 x86: add standalone verstage support
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.

Aaron Durbin d972f78e75 linking: link bootblock.elf with .data and .bss sections again
Currently coreboot expects the loader to clear the bss section
for all stages. i.e. stages don't clear their own bss. On ARM
SoCs the BootROM would be responsible for this. To do that
one needs to include the bss section data (all zeros) in the
bootblock.bin file. This was previously being attempted by
keeping the .bss info in the .data section because objcopy
happened zero out non-file allocated data section data.

Instead go back to linking bootblock with the bss section
but mark the bss section as loadable allocatable data. That
way it will be included in the binary properly when objcopy
-O binary is emplyed. Also do the same for the data section
in the case of no non-zero object values are in the data
section.

Without this change the trick of including .bss in .data
was not working when there wasn't a non-zero value object
in the data section.

BUG=None

TEST=Built emulation/qemu-armv7 and noted bootblock.bin contains

can be achieved, but for the time being that's being left out.

Some of the Chrome OS boards were directly calling vboot
called in some form after contorting around #ifdef preprocessor
macros. The reasoning is that Chrome OS doesn't always do display
initialization during startup. It's runtime dependent. While
this is a requirement that doesn't mean vboot functions should be
sprinkled around in the mainboard and chipset code. Instead provide
one function, display_init_required(), that provides the policy
for determining display initialization action. For Chrome OS
devices this function honors vboot_skip_display_init() and all
other configurations default to initializing display.

Julius Werner 8d8799a33a arm, arm64, mips: Add rough static stack size checks with -Wstack-usage
We've seen an increasing need to reduce stack sizes more and more for
space reasons, and it's always guesswork because no one has a good idea
how little is too litte. We now have boards with 3K and 2K stacks, and
old pieces of common code often allocate large temporary buffers that
would lead to very dangerous and hard to detect bugs when someone
eventually tries to use them on one of those.

This patch tries improve this situation at least a bit by declaring 2K
as the minimum stack size all of coreboot code should work with. It
checks all function frames with -Wstack-usage=1536 to make sure we don't
allocate more than 1.5K in a single buffer. This is of course not a
perfect test, but it should catch the most common situation of declaring
a single, large buffer in some close-to-leaf function (with the
assumption that 0.5K is hopefully enough for all the "normal" functions
above that).

Change one example where we were a bit overzealous and put a 1K buffer
into BSS back to stack allocation, since it actually conforms to this
new assumption and frees up another kilobyte of that highly sought-after
verstage space. Not touching x86 with any of this since it's lack of
__PRE_RAM__ BSS often requires it to allocate way more on the stack than
would usually be considered sane.

Aaron Durbin bd1499d338 timestamps: don't drop ramstage timestamps with EARLY_CBMEM_INIT
While running ramstage with the EARLY_CBMEM_INIT config the timestamp
cache was re-initialized and subsequently used. The result was that
the ramstage timestamps would be dropped from cbmem.  The reason
is that the ramstage timestamps perpetually lived in ramstage BSS
never getting sync'd back into cbmem. The fix is to honor the
cache state in ramstage in the timestamp_init() path.

Also, make cache_state a fixed bit width to allow for different
architectures across the pre-ramstage stages.

Duncan Laurie a51815119f hardwaremain: Move init_timer() call to before console init
The 8250 MMIO uart driver calls udelay, and if that is the first
call then it will also call printk in init_timer() which can result
in a deadlock trying to acquire the console lock.

There are a few options to prevent this:
1) remove the printk in init_timer which removes a useful debug message
2) change the udelay() to cpu_relax() in uart8250mem.c
3- move the init_timer() call in ramstage main() to be called earlier

Since hardwaremain.c:main() already has an explicit call to init_timer()
on x86 it is an easy change to move this to happen before the console
is initialized.

Kyösti Mälkki 4fbac46524 cbmem: Unify CBMEM init tasks with CBMEM_INIT_HOOK() API
Squashed and adjusted two changes from chromium.git. Covers
CBMEM init for ROMTAGE and RAMSTAGE.

cbmem: Unify random on-CBMEM-init tasks under common CBMEM_INIT_HOOK() API

There are several use cases for performing a certain task when CBMEM is
first set up (usually to migrate some data into it that was previously
kept in BSS/SRAM/hammerspace), and unfortunately we handle each of them
differently: timestamp migration is called explicitly from
cbmem_initialize(), certain x86-chipset-specific tasks use the
CAR_MIGRATION() macro to register a hook, and the CBMEM console is
migrated through a direct call from romstage (on non-x86 and SandyBridge
boards).

This patch decouples the CAR_MIGRATION() hook mechanism from
cache-as-RAM and rechristens it to CBMEM_INIT_HOOK(), which is a clearer
description of what it really does. All of the above use cases are
ported to this new, consistent model, allowing us to have one less line
of boilerplate in non-CAR romstages.

BUG=None
TEST=Built and booted on Nyan_Blaze and Falco with and without

cbmem: Extend hooks to ramstage, fix timestamp synching

Commit 7dd5bbd71 (cbmem: Unify random on-CBMEM-init tasks under common
CBMEM_INIT_HOOK() API) inadvertently broke ramstage timestamps since
timestamp_sync() was no longer called there. Oops.

This patch fixes the issue by extending the CBMEM_INIT_HOOK() mechanism
to the cbmem_initialize() call in ramstage. The macro is split into
explicit ROMSTAGE_/RAMSTAGE_ versions to make the behavior as clear as
possible and prevent surprises (although just using a single macro and
relying on the Makefiles to link an object into all appropriate stages
would also work).

This allows us to get rid of the explicit cbmemc_reinit() in ramstage
(which I somehow accounted for in the last patch without realizing that
timestamps work exactly the same way...), and replace the older and less
flexible cbmem_arch_init() mechanism.

Also added a size assertion for the pre-RAM CBMEM console to memlayout
that could prevent a very unlikely buffer overflow I just noticed.
