The coreboot community has done a tremendous amount of work on the
codebase over the last three and a half month. We've had over 1600
commits in that time period, doing ongoing cleanup and improvement.

It can be hard to remember at times how much the codebase really has
improved, but looking back at coreboot code from previous years, it's
really impressive the changes that have happened. We'd like to thank
everyone who has been involved in these changes. It's great to work
with everyone involved, from the people who make the small cleanup
patches and review all of the incoming changes to the people working
on new chipsets and SoCs. We'd additionally like to thank all of those
individuals who make the effort to become involved and report issues
or push even a single patch to fix a bug that they've noticed.

### cpu/mp_init.c: Only enable CPUs once they execute code
On some systems the BSP cannot know how many CPUs are present in the
system. A typical use case is a multi socket system. Setting the enable
flag only on CPUs that actually exist makes it more flexible.
### cpu/x86/smm: Add PCI resource store functionality
In certain cases data within protected memmory areas like SMRAM could
be leaked or modified if an attacker remaps PCI BARs to point within
that area. Add support to the existing SMM runtime to allow storing
PCI resources in SMRAM and then later retrieving them.
This helps prevent moving BARs around to get SMM to access memory in
areas that shouldn't be accessed.
### acpi: Add SRAT x2APIC table support
For platforms using X2APIC mode add SRAT x2APIC table
generation. This allows to setup proper SRAT tables.
### drivers/usb/acpi: Add USB _DSM method to enable/disable USB LPM per port
This patch supports projects to use _DSM to control USB3 U1/U2
transition per port.
More details can be found in
https://web.archive.org/web/20230116084819/https://learn.microsoft.com/en-us/windows-hardware/drivers/bringup/usb-device-specific-method---dsm-
The ACPI and USB driver of linux kernel need corresponding functions
to support this feature. Please see
https://git.kernel.org/pub/scm/linux/kernel/git/mnyman/xhci.git/log/?h=port_check_acpi_dsm
### drivers/efi: Add EFI variable store option support
Add a driver to read and write EFI variables stored in a region device.
This is particularly useful for EDK2 as payload and allows to reuse
existing EFI tools to set/get options used by the firmware.
The write implementation is fault tolerant and doesn't corrupt the
variable store. A faulting write might result in using the old value
even though a 'newer' had been completely written.
Implemented basic unit tests for header corruption, writing existing
data and append new data into the store.
Initial firmware region state:
Initially the variable store region isn't formatted. Usually this is
done in the EDK2 payload when no valid firmware volume could be found.
It might be useful to do this offline or in coreboot to have a working
option store on the first boot or when it was corrupted.
Performance improvements:
Right now the code always checks if the firmware volume header is valid.
This could be optimised by caching the test result in heap. For write
operations it would be good to cache the end of the variable store in
the heap as well, instead of walking the whole store. For read
operations caching the entire store could be considered.
Reclaiming memory:
The EFI variable store is append write only. To update an existing
variable, first a new is written to the end of the store and then the
previous is marked invalid. This only works on PNOR flash that allow to
clear set bits, but keep cleared bits state.
This mechanisms allows a fault tolerant write, but it also requires to
"clean" the variable store for time to time. This cleaning would remove
variables that have been marked "deleted".
Such cleaning mechanism in turn must be fault tolerant and thus must use
a second partition in the SPI flash as backup/working region.
For now to cleaning is done in coreboot.

2023-05-08 01:29:47 +02:00
Fault checking:
The driver should check if a previous write was successful and if not
mark variables as deleted on the next operation.
### drivers/ocp/ewl: Add EWL driver for EWL type 3 error handling
Add EWL (Enhanced Warning Log) driver which handles Intel EWL HOB
and prints EWL type 3 primarily associated with MRC training failures.
