Variable length arrays were a feature added in C99 that allows the
length of an array to be determined at runtime. Eg.
int sum(size_t n) {
int arr[n];
...
}
This adds a small amount of runtime overhead, but is also very
dangerous, since it allows use of an unlimited amount of stack memory,
potentially leading to stack overflow. This is only worsened in
coreboot, which often has very little stack space to begin with. Citing
concerns like this, all instances of VLA's were recently removed from the
Linux kernel. In the immortal words of Linus Torvalds [0],
AND USING VLA'S IS ACTIVELY STUPID! It generates much more code, and
much _slower_ code (and more fragile code), than just using a fixed
key size would have done. [...] Anyway, some of these are definitely
easy to just fix, and using VLA's is actively bad not just for
security worries, but simply because VLA's are a really horribly bad
idea in general in the kernel.
This patch follows suit and zaps all VLA's in coreboot. Some of the
existing VLA's are accidental ones, and all but one can be replaced with
small fixed-size buffers. The single tricky exception is in the SPI
controller interface, which will require a rewrite of old drivers
to remove [1].

Sometimes coreboot needs to compile external code (e.g.
vboot_reference) using its own set of system header files. When
these headers don't line up with C Standard Library, it causes
problems.
Create ctype.h header file. Relocate ctype.h functions from
string.h into ctype.h. Update source files which call ctype.h
functions accordingly.
Note that ctype.h still lacks five functions which are not used
in coreboot source:
isalnum, isalpha, iscntrl, isgraph, ispunct

The ASL 2.0 syntax for "!X" resolves to "LNot(X)" which will evaluate
the object as an integer and turn into a boolean. This may not do the
right thing if the object is actually a string and it can lead to
unexpected behavior.
Instead be specific about the object type and check for zero or an
empty string depending on what is being returned.
This fixes an issue where some VPD keys were causing the search to
stop and miss subsequent entries.

When coreboot checks the TPM and key-ladder state it issues a reboot of
the Cr50 with a delay parameter. Older Cr50 code doesn't support the
delay parameter and reboots immediately, which prevented coreboot from
running the mainboard specific code needed for the AP to come back up.
This change calls mainboard_prepare_cr50_reset() prior to sending the
VENDOR_CC_IMMEDIATE_RESET command.
This change also fixes a false error message from the coreboot log that
indicated "Unexpected Cr50 TPM mode 3" when the Cr50 key ladder is
disabled.

This change adds support for providing a MAC address that can be used
by the OS network drivers to change the MAC address that a NIC uses.
The Realtek r8152 driver in the Linux kernel supports a MAC address
passthru feature which can result in the dock ethernet port using the
same MAC address that is assigned to the internal NIC. This is done
by calling an ACPI method at \_SB.AMAC() which returns a formatted
string containing the MAC address for the dock to use.
The Linux kernel implementation can be found at
drivers/net/usb/r8152.c:vendor_mac_passthru_addr_read()
This is implemented specifically for Chrome OS as it relies on VPD
to determine the MAC address to supply.
The policy which controls where the dock MAC address comes from is
written into RW_VPD property "dock_passthru":
"dock_mac" or empty: Use MAC address from RO_VPD value "dock_mac"
"ethernet_mac0": Use MAC address from RO_VPD value "ethernet_mac0"
"builtin": existing dock MAC address (return nothing)
The MAC address in VPD is the standard format AA:BB:CC:DD:EE:FF and
it must be converted into the string format expected by the OS which
involves some string manipulation which ACPI is not great at handling.
BUG=b:123925776
TEST=this was tested on a sarien board by setting the VPD keys to
their expected values and observing if the AMAC() method returns the
expected string.

When <symbols.h> was first introduced, it only declared a handful of
regions and we didn't expect that too many architectures and platforms
would need to add their own later. However, our amount of platforms has
greatly expanded since, and with them the need for more special memory
regions. The amount of code duplication is starting to get unsightly,
and platforms keep defining their own <soc/symbols.h> files that need
this as well.
This patch adds another macro to cut down the definition boilerplate.
Unfortunately, macros cannot define other macros when they're called, so
referring to region sizes as _name_size doesn't work anymore. This patch
replaces the scheme with REGION_SIZE(name).
Not touching the regions in the x86-specific <arch/symbols.h> yet since
they don't follow the standard _region/_eregion naming scheme. They can
be converted later if desired.

Have the generated Chrome OS ACPI GPIO table provide the ACPI GPIO
pin number instead of the raw GPIO number when possible.
This is necessary if the OS uses a different numbering for GPIOs
that are reported in ACPI than the actual underlying GPIO number.
For example, if the SOC OS driver declares more pins in an ACPI GPIO
bank than there are actual pins in the hardware it will have gaps in
the number space.
This is a reworked version of 6217e9beff16d805ca833e79a2931bcdb3d02a44

There is a confusingly named section in cbmem called vdat.
This section holds a data structure called chromeos_acpi_t,
which exposes some system information to the Chrome OS
userland utility crossystem.
Within the chromeos_acpi_t structure, there is a member
called vdat. This (currently) holds a VbSharedDataHeader.
Rename the outer vdat to chromeos_acpi to make its purpose
clear, and prevent the bizarreness of being able to access
vdat->vdat.
Additionally, disallow external references to the
chromeos_acpi data structure in gnvs.c.

The virtualized developer switch was invented five years ago and has
been used on every vboot system ever since. We shouldn't need to specify
it again and again for every new board. This patch flips the Kconfig
logic around and replaces CONFIG_VIRTUAL_DEV_SWITCH with
CONFIG_PHYSICAL_DEV_SWITCH, so that only a few ancient boards need to
set it and it fits better with CONFIG_PHYSICAL_REC_SWITCH. (Also set the
latter for Lumpy which seems to have been omitted incorrectly, and hide
it from menuconfig since it's a hardware parameter that shouldn't be
configurable.)
Since almost all our developer switches are virtual, it doesn't make
sense for every board to pass a non-existent or non-functional developer
mode switch in the coreboot tables, so let's get rid of that. It's also
dangerously confusing for many boards to define a get_developer_mode()
function that reads an actual pin (often from a debug header) which will
not be honored by coreboot because CONFIG_PHYSICAL_DEV_SWITCH isn't set.
Therefore, this patch removes all those non-functional instances of that
function. In the future, either the board has a physical dev switch and
must define it, or it doesn't and must not.
In a similar sense (and since I'm touching so many board configs
anyway), it's annoying that we have to keep selecting EC_SOFTWARE_SYNC.
Instead, it should just be assumed by default whenever a Chrome EC is
present in the system. This way, it can also still be overridden by
menuconfig.

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).

is disabled by the boot loader, depthcharge. Since the bootloader
isn't involved in resuming a suspended machine there's no equivalent
action in coreboot to disable the platform hierarchy. Therefore, to

needs to be disabled as well. For systems that resume using the

On some x86 platforms (skylake, apollolake), we observe reboots at
different steps during the FSP initialization. These additional reboots
result in loss of recovery request because vboot_reference library
clears recovery request on vbnv once verification is complete and it has
made a decision about which boot path to take(normal/dev, slot-a/slot-b,
recovery).
Provide a way to allow mainboards/chipsets to inform recovery module in
vboot2 to save recovery reason to survive unexpected reboots. The
recovery reason is set in vbnv after vboot_reference library completes
its verification and clears the reason in vbnv while jumping to

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.

If read_vbnv finds that the vbnv_copy is not valid, it initializes it
with the correct HEADER_SIGNATURE and other attributes. However, the
vbnv copy is checked for validity and initialized at the vboot layer as
well. Since, vboot is the owner of this data, it should be the one
initializing it. Thus, if read_vbnv sees that the data is not valid,
simply reset it to all 0s and let vboot layer take care of it. This also
removes the need for additional checks to ensure that the dirty vbnv
copy is properly updated on storage.

Update read_vbnv to return a value depending upon whether it wants a

Until now it was assumed that all TPM devices were of the same type
(TCG 1.2 spec compliant) and x86 based boards had LPC connected TPMs
and all other boards had I2C connected TPMs.
With the advent of TPM2 specification there is a need to be able to
configure different combinations of TPM types (TPM or TPM2) and
interfaces (LPC, I2C and SPI).
This patch allows to do it. Picking Chrome OS still assumes that the
board has a TPM device, but adding MAINBOARD_HAS_TPM2 to the board's
Kconfig will trigger including of TPM2 instead.
MAINBOARD_HAS_LPC_TPM forces the interface to be set to LPC, adding
SPI_TPM to the board config switches interface choice to SPI, and if
neither of the two is defined, the interface is assumed to be I2C.

The VBOOT_OPROM_MATTERS configuration option signals to vboot that the
board can skip display initialization in the normal boot path. It's name
is a left-over from a time when this could only happen by avoiding
loading the VGA option ROM on x86 devices. Now we have other
boards that can skip their native display initialization paths too, and
the effect to vboot is the same. (Really, we should rename oprom_matters
and oprom_loaded to display_skippable and display_initialized or
something, but I don't think that's worth the amount of repositories
this would need to touch.)
The only effect this still has in today's vboot is to reboot and
explicitly request display initialization for EC software sync on
VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still,
the vboot flag just declares the capability (for skipping display init),
and it should be set correctly regardless of whether that actually makes
a difference on a given platform (right now). This patch updates all
boards/SoCs that have a conditional path based on
display_init_required() accordingly.

The MT8173 hardware watchdog can assert an external signal which we use
to reset the TPM on Oak. Therefore we do not need to do the same
double-reset dance as on other Chromebooks to ensure that we reset in a
correct state.
Still, we have a situation where we need to reconfigure the watchdog
early in the bootblock in a way that will clear information about the
previous reboot from the status register, and we need that information
later in ramstage to log the right event. Let's reuse the same watchdog
tombstone mechanism from other boards, except that we don't perform a
second reset and the tombstone is simply used to communicate between
bootblock and ramstage within the same boot.
BRANCH=None
BUG=None
TEST=Run 'mem w 0x10007004 0x8' on Oak, observe how it reboots and how
'mosys eventlog list' shows a hardware watchdog reboot event afterwards.

When doing verification of memory init code in verstage vboot
should issue a TPM_Startup(ST_STATE) instead of TPM_Startup(ST_CLEAR)
in order to preserve the flags in TPM_STCLEAR_FLAGS which include
things like physical presence. In doing so we can also skip the rest
of the TPM init work in this function in the S3 resume path.
BUG=chrome-os-partner:50633
BRANCH=glados
TEST=S3 resume on chell and ensure TPM is resumed instead of being
cleared and that 'tpmc getvf|getpf|getf' does not show any difference
in flags between boot and resume.

If a platform does verification of the memory init step, and it must
resume with the same slot that it booted from then it needs to set
the vboot context flag when resuming instead of booting. This will
affect the slot that is selected to verify and resume from.
BUG=chromium:577269
BRANCH=glados
TEST=manually tested on chell:
1) ensure that booting from slot A resumes from slot A.
2) ensure that booting from slot B resumes from slot B.
3) do RW update while booted from slot A (so the flags are set to try
slot B) and ensure that suspend/resume still functions properly using
current slot A.
4) do RW update while booted from slot B (so the flags are set to try
slot A) and ensure that suspend/resume still functions properly using
current slot B.

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).
