Change in coreboot[master]: soc/intel/{cnl,icl}: Enable support to configure interrupt overrides
by Aamir Bohra (Code Review) 09 Nov '20

09 Nov '20

Aamir Bohra has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/34517 ) Change subject: soc/intel/{cnl,icl}: Enable support to configure interrupt overrides ...................................................................... soc/intel/{cnl,icl}: Enable support to configure interrupt overrides This implementation selects SOC_INTEL_COMMON_ITSS_INTERRUPT_OVERRIDE config. It would enable support from SOC to dynamically populate the PCI IRQ routing table based on the devices enabled from the mainboard. And pass the same to FSP to configure the IRQ entries in ITSS PIRx register. The same table can be used to generate the ACPI PIRQ mapping table.

Change in coreboot[master]: soc/intel/basecode: Add support for updating ucode loaded via FIT
by Sugnan Prabhu S (Code Review) 09 Nov '20

09 Nov '20

Sugnan Prabhu S has uploaded a new patch set (#64) to the change originally created by Rizwan Qureshi. ( https://review.coreboot.org/c/coreboot/+/27369 ) Change subject: soc/intel/basecode: Add support for updating ucode loaded via FIT ...................................................................... soc/intel/basecode: Add support for updating ucode loaded via FIT Intel’s FIT (Firmware Interface Table) based MCU (microcode/pcode patch) loading mechanism patches the microcode before CPU reset. In the current Chromebooks, field updatable FW has to be first verified by vboot. Since the MCU is loaded before reset, vboot cannot verify the same and hence we end up restricting FIT based MCU update only from RO. This patch implements a scheme which will allow chromebooks to update MCU in the field. Create 2 bootblocks (use INTEL_ADD_TOP_SWAP_BOOTBLOCK) each containing their own FIT table. First bootblock FIT has pointers to MCUs (in microcode_blob.bin) which resides in RO section. This will be used in the recovery scenario and also when booting with top-swap disabled i.e, RTC reset. Second bootblock (Normal mode) is identical to the first one except the FIT. Insert an additional pointer to a MCU that will reside in a staging area. Use the CONFIG_INTEL_TOP_SWAP_FIT_ENTRY_FMAP_REG config to insert the address of the staging area into FIT. Top swap control bit in RTC BUC register (0x3414) is used to switch between the two bootblocks. Reserve a region in the FMAP which is equal to or greater than the MCU size specified in the BWG for a particular SoC (e.g., for Skylake/Kaby Lake it is 192K). This is a RW region just like the RW_MRC_CACHE. MCU from RW-A/RW-B will be copied to this region during boot. Protect this staging area with a FPR. Basic update flow: In non-recovery mode, Once a slot has been selected and loaded, check if the current slot MCU and RW staging MCU are same. If not, update the staging area with the MCU found in the current slot and reset the system. Also, make sure that the top-swap is enabled in normal/developer mode and disabled in recovery mode. In order to enable the update feature: * The mainboard chromeos.fmd should include a new region for staging MCU e.g, RW_UCODE_STAGED. * Select config INTEL_TOP_SWAP_MULTI_FIT_UCODE_UPDATE. * Implement a call to check_and_update_ucode() and handle the failure appropriately. Add documentation to describing the MCU update procedure. Update config name and Makefile.inc TODO: Since this update mechanism is dealing mostly with a single MCU it is best suited for systems where the CPU is soldered down and not replaceable (socketed). Extend the update mechanism to systems where the CPU is replaceable, by including multiple MCU for different CPUs. TEST=Create an FW image for soraka and flash, create a chromeos-firmwareupdate shellball with a newer MCU and perform an update. Make sure that the currently loaded microcode version matches the one in firmwareupdate.
