### Add [AMD] apcb_v3_edit tool
apcb_v3_edit.py tool edits APCB V3 binaries. Specifically it will inject
up to 16 SPDs into an existing APCB. The APCB must have a magic number
at the top of each SPD slot.
### Allow enable/disable ME via CMOS
Add .enable method that will set the CSME state. The state is based on
the new CMOS option me_state, with values of 0 and 1. The method is very
stable when switching between different firmware platforms.
This method should not be used in combination with USE_ME_CLEANER.
State 1 will result in:
ME: Current Working State : 4
ME: Current Operation State : 1
ME: Current Operation Mode : 3
ME: Error Code : 2
State 0 will result in:
ME: Current Working State : 5
ME: Current Operation State : 1
ME: Current Operation Mode : 0
ME: Error Code : 0
### Move LAPIC configuration to MP init
Implementation for setup_lapic() did two things -- call
enable_lapic() and virtual_wire_mode_init().
In PARALLEL_MP case enable_lapic() was redundant as it
was already executed prior to initialize_cpu() call.
For the !PARALLEL_MP case enable_lapic() is added to
AP CPUs.
### Add ANSI escape sequences for highlighting
This patch adds ANSI escape sequences to highlight a log line based on
its loglevel to the output of "interactive" consoles that are meant to
be displayed on a terminal (e.g. UART). This should help make errors and
warnings stand out better among the usual spew of debug messages. For
users whose terminal or use case doesn't support these sequences for
some reason (or who simply don't like them), they can be disabled with a
Kconfig.
While ANSI escape sequences can be used to add color, minicom (the
presumably most common terminal emulator for UART endpoints?) doesn't
support color output unless explicitly enabled (via -c command line
flag), and other terminal emulators may have similar restrictions, so in
an effort to make this as widely useful by default as possible I have
chosen not to use color codes and implement this highlighting via
bolding, underlining and inverting alone (which seem to go through in
all cases). If desired, support for separate color highlighting could be
added via Kconfig later.
### Add cbmem_dump_console
This function is similar to cbmem_dump_console_to_uart except it uses
the normally configured consoles. A console_paused flag was added to
prevent the cbmem console from writing to itself.
### Add coreboot-configurator
A simple GUI to change settings in coreboot's CBFS, via the nvramtool utility.
### Update to NixOS 21.11
Update configs so that they work with NixOS 21.11. Drop `iasl` package
since it was replaced with `acpica-tools`.
### Move to v2021.10
Move to building the latest U-Boot.
### Support systems with >128 cores
Each time the spinlock is acquired a byte is decreased and then the
sign of the byte is checked. If there are more than 128 cores the sign
check will overflow. An easy fix is to increase the word size of the
spinlock acquiring and releasing.
### Add [samsung] sx9360 [proximity sensor] driver
Add driver for setting up Semtech sx9360 SAR sensor.
The driver is based on sx9310.c. The core of the driver is the same, but
the bindings are slightly different.
Registers are documented in the kernel tree:
Documentation/devicetree/bindings/iio/proximity/semtech,sx9360.yaml
[https://patchwork.kernel.org/project/linux-iio/patch/20211213024057.3824985-4-gwendal@chromium.org/]
### Add driver for Genesys Logic [SD Controller] GL9750
The device is a PCIe Gen1 to SD 3.0 card reader controller to be
used in the Chromebook. The datasheet name is GL9750S and the revision
is 01.
The patch disables ASPM L0s.
### Add support for Realtek RT8125
The Realtek RT8168 and RT8125 have a similar programming interface,
therefore add the PCI device ID for the RT8125 into driver for support.
### Add Fibocom 5G WWAN ACPI support
Support PXSX._RST and PXSX.MRST._RST for warm and cold reset.
PXSX._RST is invoked on driver removal.
build dependency:
soc/intel/common/block/pcie/rtd3
This driver will use the rtd3 methods for the same parent in the device
tree. The rtd3 chip needs to be added on the same root port in the
devicetree separately.
### Fix bug in vr_config
The `cpu_get_power_max()` function returns the TDP in milliwatts, but
the vr_config code interprets the value in watts. Divide the value by
1000 to fix this.
This also fixes an integer overflow when `cpu_get_power_max()` returns
a value greater than 65535 (UINT16_MAX).
### Make mixed topo work
When using a mixed memory topology with DDR4, it's not possible to boot
when no DIMMs are installed, even though memory-down is available. This
happens because the DIMM SPD length defaults to 256 when no DIMM SPD is
available. Relax the length check when no DIMMs are present to overcome
this problem.
### Add FSP 2.3 support
FSP 2.3 specification introduces following changes:
1. FSP_INFO_HEADER changes
Updated SpecVersion from 0x22 to 0x23
Updated HeaderRevision from 5 to 6
Added ExtendedImageRevision
FSP_INFO_HEADER length changed to 0x50
2. Added FSP_NON_VOLATILE_STORAGE_HOB2
Following changes are implemented in the patch to support FSP 2.3:
- Add Kconfig option
- Update FSP build binary version info based on ExtendedImageRevision
field in header
- New NV HOB related changes will be pushed as part of another patch
### Join hash calculation for verification and measurement
This patch moves the CBFS file measurement when CONFIG_TPM_MEASURED_BOOT
is enabled from the lookup step into the code where a file is actually
loaded or mapped from flash. This has the advantage that CBFS routines
which just look up a file to inspect its metadata (e.g. cbfs_get_size())
do not cause the file to be measured twice. It also removes the existing
inefficiency that files are loaded twice when measurement is enabled
(once to measure and then again when they are used). When CBFS
verification is enabled and uses the same hash algorithm as the TPM, we
are even able to only hash the file a single time and use the result for
both purposes.
### Skip FSP Notify APIs
Alder Lake SoC deselects Kconfigs as below:
- USE_FSP_NOTIFY_PHASE_READY_TO_BOOT
- USE_FSP_NOTIFY_PHASE_END_OF_FIRMWARE
to skip FSP notify APIs (Ready to boot and End of Firmware) and make
use of native coreboot driver to perform SoC recommended operations
prior booting to payload/OS.
Additionally, created a helper function `heci_finalize()` to keep HECI
related operations separated for easy guarding again config.
TODO: coreboot native implementation to skip FSP notify phase API (post
pci enumeration) is still WIP.
### Add support for PCIe Resizable BARs
Section 7.8.6 of the PCIe spec (rev 4) indicates that some devices can
indicates support for "Resizable BARs" via a PCIe extended capability.
When support this capability is indicated by the device, the size of
each BAR is determined in a different way than the normal "moving
bits" method. Instead, a pair of capability and control registers is
allocated in config space for each BAR, which can be used to both
indicate the different sizes the device is capable of supporting for
the BAR (powers-of-2 number of bits from 20 [1 MiB] to 63 [8 EiB]), and
to also inform the device of the size that the allocator actually
reserved for the MMIO range.
This patch adds a Kconfig for a mainboard to select if it knows that it
will have a device that requires this support during PCI enumeration.
If so, there is a corresponding Kconfig to indicate the maximum number
of bits of address space to hand out to devices this way (again, limited
by what devices can support and each individual system may want to
support, but just like above, this number can range from 20 to 63) If
the device can support more bits than this Kconfig, the resource request
is truncated to the number indicated by this Kconfig.
