PCR documentation usage changes for coreboot 4.8.1 and newer versions#42
Merged
Conversation
Documentation changes linked to PCR usage in coreboot 4.8.1 and newer versions, to be applied at the same time as linuxboot/heads#793 is merged. Linked to VBOOT+Measured boot/Measured boot changes applied directly in coreboot so that we have a common base prior of going linuxboot/heads#709 and linuxboot/heads#721 @PatrickRudolph comments welcome

is the comment re: MRC meant to imply that we should measure the MRC blob / FSP-M separately from romstage? |

@MrChromebox as I understood, coreboot VBOOT+measuredboot/measuredboot will measure it all under PCR2. @osresearch intention was to seperate them initially. Coreboot merges them all in. I would just remove that comment. @MrChromebox opinion? |

+1 on removing the comment |
Removed comment about MRC needing to be measured into different PCR since coreboot is merging them all under PCR2 in newer VBOOT+measured boot/measuredboot Ref:https://doc.coreboot.org/security/vboot/measured_boot.html
