Actually https://review.coreboot.org/#/c/18504/ https://review.coreboot.org/#/c/18511/ (not sure if needed) and https://review.coreboot.org/#/c/18513/ (works but might be improved) fix this issue. -- Arthur Heymans -- coreboot mailing list: [email protected] https://www.coreboot.org/mailman/listinfo/coreboot
