coreboot 24.05 release
========================================================================
The coreboot project is pleased to announce the release of coreboot version
24.05. This update represents three months of hard work and commitment from our
community. With over 20 new members and contributions from more than a hundred
fifty other people in coding, reviewing patches, and other areas, this release
showcases the strength of our collaborative efforts.
With this release, coreboot has expanded its support, adding 25 new platforms or
variants and 2 new processors, further demonstrating our dedication to offering
flexible and adaptable firmware solutions. From laptops and servers to embedded
devices, coreboot 24.05 is designed to enhance a variety of hardware platforms
with its strong features.
We are grateful to all the contributors who have made this release possible.
Your expertise and collaborative efforts continue to propel the coreboot project
forward. We value the participation of everyone in the community, from long-time
developers to those new to the project, and encourage you to explore the new
opportunities that coreboot 24.05 offers.
Our next release will be 24.08, scheduled for mid-August.
Significant or interesting changes
----------------------------------
### Mark 64-bit support as stable
A significant amount of work has gone into fully supporting 64-bit coreboot
builds. There are still additional pieces that are happening, but with SMM
holding page tables itself, we can consider SMM support stable and safe enough
for general use.
### security/tpm: support compiling in multiple TPM drivers
Previously, boards could only be built with code supporting TPM 1.x or TPM 2.x
specifications. This has been updated with code allowing both to be built in
simultaneously, allowing the system to query the TPM. For systems with
soldered-down TPMs or firmware TPM solutions, it’s still possible to specify a
single TPM version so that the code for the other version isn’t included.
### arch/arm64: Add EL1/EL2/EL3 support for arm64
Previously, arch/arm64 required coreboot to run on EL3 due to EL3 register
access. This might be an issue when, for example, one boots into TF-A first and
drops into EL2 for coreboot afterwards.
This patch aims at making arch/arm64 more versatile by removing the current EL3
constraint and allowing arm64 coreboot to run on EL1, EL2 and EL3.
The strategy is to add a Kconfig option (ARM64_CURRENT_EL) which allows us to
specify coreboot's EL upon entry. Based on that, we access the appropriate ELx
registers. So, for example, when running coreboot on EL1, we would not access
vbar_el3 or vbar_el2 but instead vbar_el1. This way, we don't generate faults
when accessing higher-EL registers.
Additional coreboot changes
---------------------------
* util/smmstoretool: support processing ROMs
* cpu/x86: Link page tables in stage if possible
* lib/lzmadecode: Allow for 8 byte reads on 64bit to speed up decompression
