Change in coreboot[master]: mb/google/puff: add a region to cache SPD data
by Jamie Chen (Code Review) 04 May '20

Hello build bot (Jenkins), Furquan Shaikh, Tim Wawrzynczak, Edward O'Callaghan, Kane Chen, I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/40415 to look at the new patch set (#5). Change subject: mb/google/puff: add a region to cache SPD data ...................................................................... mb/google/puff: add a region to cache SPD data This patch adds a SPI rom region RW_SPD_CACHE on Puff and it can be used on spd_cache to reduce reading SPD data from SODIMM by smbus. It's for saving the boot time and it can be used to trigger MRC retraining when memory DIMM is changed. BUG=b:146457985 BRANCH=None TEST=Build puff successfully and verified below two items. 1.

Change in coreboot[master]: soc/intel/common/block/cse: Add boot partition related APIs
by Patrick Georgi (Code Review) 04 May '20

04 May '20

Patrick Georgi has submitted this change. ( https://review.coreboot.org/c/coreboot/+/35402 ) Change subject: soc/intel/common/block/cse: Add boot partition related APIs ...................................................................... soc/intel/common/block/cse: Add boot partition related APIs In CSE Firmware Custom SKU, CSE region is logically divided into 2 boot partitions. These boot partitions are represented by BP1(RO), BP2(RW). With CSE Firmware Custom SKU, CSE can boot from either RO(BP1) or RW(BP2). The CSE Firmware Custom SKU layout appears as below: ------------- -------------------- --------------------- |CSE REGION | => | RO | RW | DATA | => | BP1 | BP2 | DATA | ------------- -------------------- --------------------- In order to support CSE FW update to RW region, below APIs help coreboot to get info about the boot partitions, and allows coreboot to set CSE to boot from required boot partition (either RO(BP1) or RW(BP2)). GET_BOOT_PARTITION_INFO - Provides info on available partitions in the CSE region. The API provides info on boot partitions like start/end offsets of a partition within CSE region, and their version and partition status. SET_BOOT_PARTITION_INFO - Sets CSE's next boot partition to boot from. With the HECI API, firmware can notify CSE to boot from RO(BP1) or RW(BP2) on next boot. As system having CSE Firmware Custom SKU, boots from RO(BP1) after G3, so coreboot sets CSE to boot from RW(BP2) in normal mode and further, coreboot ensure CSE to boot from whichever is selected boot partition if system is in recovery mode.
