What we planned

Improve the support of TPM2 in coreboot and SeaBIOS. Currently there is only the TCPA (TPM1.2) log support in coreboot. Additionally SeaBIOS overwrites existing entries in TPM2 log area. cbmem utility also lacks support for displaying TPM2 log area.

WORK IN PROGRESS
Reorganize runtime configuration by making it persistent across updates and accessible from user space. Also prepare a tool for offline binary modification.

WORK IN PROGRESS
Vital Product Data (VPD) support. User will have possibility to store and change VPD configuration in Read-Write section of SPI flash. Moreover, default VPD keys and values will be stored in Read-Only region to protect data against corruption. Also, sortbootorder runtime configuration will be stored in VPD Read-Write section, so access to it will be possible in OS via dedicated util.

ACPI Thermal Zones implementation. BSD systems suffer from lack of Thermal Zones and lack of temperature status on the dashboards of router distributions of BSD systems.
