Change in ...coreboot[master]: mb/google/mistral: Ignore REC switch if TPM isn't ready
by Patrick Georgi (Code Review) 11 Mar '20

11 Mar '20

Hello SANTHOSH JANARDHANA HASSAN, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/32272 to review the following change. Change subject: mb/google/mistral: Ignore REC switch if TPM isn't ready ...................................................................... mb/google/mistral: Ignore REC switch if TPM isn't ready The recovery button's state is cached in the TPM, but on first boot Cr50 isn't ready yet for this task, which leads to a reboot further down the road (to get TPM up). To not confuse matters further, only act on the recovery button if the TPM is in fact able to cache the state.

Change in ...coreboot[master]: TEMP: NOT FOR REVIEW: google/mistral: Limit FDR detection for verstage

Yuji Sasaki has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/32904 Change subject: TEMP: NOT FOR REVIEW: google/mistral: Limit FDR detection for verstage ...................................................................... TEMP: NOT FOR REVIEW: google/mistral: Limit FDR detection for verstage FDR switch detection and LED state change must only be functional when called in verstage. get_recovery_mode_switch() is called from ramstage as part of elog function but this is informational purpose, should not affecting LED state and boot mode. This CL is adding #if directives to limit FDR detection for verstage. When get_recovery_mode_switch() is called from other stages, it just return current FDR switch state but do not change LED state or boot mode. BUG=b:131622855 TEST=Build and run on DUT, keep pushing FDR switch and power on, verify it do not fall into secondary FDR detection loop in ramstage after "recovery requested" in verstage.
