2020-05-04soc/intel/common/block/cse: Add boot partition related APIsSridhar Siricilla
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.

2020-03-18soc: Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

2020-03-15soc/intel/common/block/cse: Modify handling of HMRFPO_ENABLE commandSridhar Siricilla
Below changes are done: 1. Allow execution of HMRFPO_ENABLE command if CSE meets below prerequisites: - Current operation mode(COM) is Normal and Curret working state(CWS) is Normal. -(or) COM is Soft Temp Disable and CWS is Normal if ME's Firmware SKU is Custom. 2. Check response status. 3. Add documentation for send_hmrfpo_enable_msg(). 4. Rename padding field of hmrfpo_enable_resp to reserved. The HMRFPO (Host ME Region Flash Protection Override) mode prevents CSE to execute SPI I/O cycles to CSE region, and unlocks the CSE region to perform updates to it. This command is only valid before EOP(End of Post). For Custom SKU, follow below procedure to place CSE in HMRFPO mode: 1. Ensure CSE boots from BP1. When CSE boots from BP1, it will have opmode Temp Disable Mode. 2. Send HMRFPO_ENABLE command to CSE. Then, CSE enters HMRFPO mode. CSE Firmware Custom SKU Image Layout: = [RO] + [RW + DATA PART] = [BP1] + [BP2 + DATA PART] Here, BP1 will have reduced functionality of BP2, and the BP1 will be CSE's RO partition and [BP2 + DATA PART] together will represent CSE's RW partition. CSE can boot from either BP1(RO) or BP2(RW). CSE Image Layout in Consumer SKU: BP2 + BP3 + DATA PART TEST=Verfied on hatch board.
