Hello Patrick Rudolph, Subrata Banik, Balaji Manigandan, Aamir Bohra, Rizwan Qureshi, V Sowmya, build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, Furquan Shaikh,
I'd like you to reexamine a change. Please visit
https://review.coreboot.org/c/coreboot/+/35402
to look at the new patch set (#38).
Change subject: soc/intel/common/block/cse: Add boot partition related APIs ......................................................................
soc/intel/common/block/cse: Add boot partition related APIs
The CSE region is logically divided into 3 boot partitions when redundancy is enabled. These boot partitions are represented by BP1, BP2 and BP3. In chrome, CSE can boot from either BP1 or BP2. The CSE image layout appears as below.. ------------- ------------------ -------------------------- |CSE REGION | => | RO | RW | => | BP1 | BP2 + BP3 + DATA | ------------- ------------------ --------------------------
In order to support CSE FW update to RW region, below APIs help coreboot to get info about the boot partitions, and allows the coreboot to set CSE to boot from required boot partition(either BP1(RO) or 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 the next boot partition to boot for CSE. With the HECI API, firmware can notify CSE to boot from BP1 or BP2 on next boot.
