In this talk, we briefly look back at the works we have published to the upstream coreboot for Intel Sapphire Rapids, and present the improvement we have made for Cloud Firmware that has been verified on Intel Birch Stream.

Besides those specific features for Intel FSP, other improvement can be applied to all platforms (X86 and ARM).

With the enhancement of debugging and the system booting process (e.g., dynamically enable FSP log, dynamically overwrite Linux payload’s kernel command line, optionally skip MRC training by reusing the current MRC data for faster boot time after an image update), we believe the community can benefit from our work.
