For bit fields with 31 bits (e.g: DEFINE_BITFIELD(MYREG, 30, 0) ),
the calculation of mask value will go overflow:
"error: integer overflow in expression '-2147483648 - 1' of
type 'int' results in '2147483647'".
And for bit fields with 32 bits (e.g: DEFINE_BITFIELD(MYREG, 31, 0) ),
the error will be:
"error: left shift count >= width of type [-Werror=shift-count-overflow]"
To fix these issues, the bit field macros should always use unsigned
integers, and use 64bit integer when creating mask value.

Currently, those who want to use measured boot implemented within
vboot should enable verified boot first, along with sections such
as GBB and RW slots defined with manually written fmd files, even
if they do not actually want to verify anything.
As discussed in CB:34977, measured boot should be decoupled from
verified boot and make them two fully independent options. Crypto
routines necessary for measurement could be reused, and TPM and CRTM
init should be done somewhere other than vboot_logic_executed() if
verified boot is not enabled.
In this revision, only TCPA log is initialized during bootblock.
Before TPM gets set up, digests are not measured into tpm immediately,
but cached in TCPA log, and measured into determined PCRs right after
TPM is up.
This change allows those who do not want to use the verified boot
scheme implemented by vboot as well as its requirement of a more
complex partition scheme designed for chromeos to make use of the
measured boot functionality implemented within vboot library to
measure the boot process.

Sometimes coreboot needs to compile external code (e.g.

When these headers don't line up with C Standard Library,
it causes problems.
Create stdio.h and stdarg.h header files. Relocate snprintf
into stdio.h and vsnprintf into stdarg.h from string.h.
Chain include these header files from string.h, since coreboot
doesn't care so much about the legacy POSIX location of these
functions.
Also move va_* definitions from vtxprintf.h into stdarg.h where
they belong (in POSIX). Just use our own definitions regardless
of GCC or LLVM.

This CL has changes that allow us to enable a configurable

To enable it, we add two new variables to src/Kconfig
CONFIGURABLE_RAMSTAGE
is the overall variable controlling other options for minimizing the
ramstage.
MINIMAL_PCI_SCANNING is how we indicate we wish to enable minimal
PCI scanning.
Some devices must be scanned in all cases, such as 0:0.0.
To indicate which devices we must scan, we add a new mandatory
keyword to sconfig
It is used in place of on, off, or hidden, and indicates
a device is enabled and mandatory. Mandatory
devices are always scanned. When MINIMAL_PCI_SCANNING is enabled,
ONLY mandatory devices are scanned.
We further add support in src/device/pci_device.c to manage
both MINIMAL_PCI_SCANNING and mandatory devices.
Finally, to show how this works in practice, we add mandatory
keywords to 3 devices on the qemu-q35.

This update is a combination of all four of the patches so that the

breakage is because of the cross-dependencies between the original
separate patches would cause failure because of data structure changes.
security/intel/stm
This directory contains the functions that check and move the STM to the
MSEG, create its page tables, and create the BIOS resource list.
The STM page tables is a six page region located in the MSEG and are
pointed to by the CR3 Offset field in the MSEG header. The initial
page tables will identity map all memory between 0-4G. The STM starts
in IA32e mode, which requires page tables to exist at startup.
The BIOS resource list defines the resources that the SMI Handler is
allowed to access. This includes the SMM memory area where the SMI
handler resides and other resources such as I/O devices. The STM uses
the BIOS resource list to restrict the SMI handler's accesses.
The BIOS resource list is currently located in the same area as the
SMI handler. This location is shown in the comment section before
smm_load_module in smm_module_loader.c
Note: The files within security/intel/stm come directly from their
Tianocore counterparts. Unnecessary code has been removed and the
remaining code has been converted to meet coreboot coding requirements.

This change adds support for allocating resources for PCI express hotplug
bridges when PCIEXP_HOTPLUG is selected. By default, this will add 32 PCI
subordinate numbers (buses), 256 MiB of prefetchable memory, 8 MiB of
non-prefetchable memory, and 8 KiB of I/O space to any device with the
PCI_EXP_SLTCAP_HPC bit set in the PCI_EXP_SLTCAP register, which
indicates hot-plugging capability. The resource allocation is configurable,
please see the PCIEXP_HOTPLUG_* variables in src/device/Kconfig.
In order to support the allocation of hotplugged PCI buses, a new field
is added to struct device called hotplug_buses. This is defaulted to
zero, but when set, it adds the hotplug_buses value to the subordinate
value of the PCI bridge. This allows devices to be plugged in and
unplugged after boot.
This code was tested on the System76 Darter Pro (darp6). Before this
change, there are not enough resources allocated to the Thunderbolt
PCI bridge to allow plugging in new devices after boot. This can be
worked around in the Linux kernel by passing a boot param such as:
pci=assign-busses,hpbussize=32,realloc
This change makes it possible to use Thunderbolt hotplugging without
kernel parameters, and attempts to match closely what our motherboard
manufacturer's firmware does by default.

The names of each spi flash cause quite a bit of bloat in the text
size of each stage/program. Remove the name entirely from spi flash
in order to reduce overhead. In order to pack space as closely as
possible the previous 32-bit id and mask were split into 2 16-bit
ids and masks.
On Chrome OS build of Aleena there's a savings of >2.21KiB in each
of verstage, romstage, and ramstage.

This patch creates a new commonlib/bsd subdirectory with a similar
purpose to the existing commonlib, with the difference that all files
under this subdirectory shall be licensed under the BSD-3-Clause license
(or compatible permissive license). The goal is to allow more code to be
shared with libpayload in the future.
Initially, I'm going to move a few files there that have already been
BSD-licensed in the existing commonlib. I am also exracting most
contents of the often-needed <commonlib/helpers.h> as long as they have
either been written by me (and are hereby relicensed) or have an
existing equivalent in BSD-licensed libpayload code. I am also
relicensing <commonlib/compression.h> (written by me) and
<commonlib/compiler.h> (same stuff exists in libpayload).
Finally, I am extracting the cb_err error code definitions from
<types.h> into a new BSD-licensed header so that future commonlib/bsd
code can build upon a common set of error values. I am making the
assumption here that the enum constants and the half-sentence fragments
of documentation next to them by themselves do not meet the threshold of
copyrightability.
