Hello Yuji Sasaki, I'd like you to do a code review. Please visit https://review.coreboot.org/c/coreboot/+/32693 to review the following change. Change subject: TEMP: NOT FOR REVIEW: google/mistral: Add LP5562 driver ...................................................................... TEMP: NOT FOR REVIEW: google/mistral: Add LP5562 driver Add LP5562 driver to mistral board file. BUG=b:116352348 TEST=build coreboot and chromeos-bootimage, run on mistral.

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.
