This reverts commit adb393bdd6cd6734fa2672bd174aca4588a68016. This relands commit 6260bf712a836762b18d80082505e981e040f4bc. Reason for revert: The original CL did not handle some devices correctly. With the fixes: * commit 36721a4 (mb/google/brya: Add GPIO_IN_RW to all variants' early GPIO tables) * commit 3bfe46c (mb/google/guybrush: Add GPIO EC in RW to early GPIO tables) * commit 3a30cf9 (mb/google/guybrush: Build chromeos.c in verstage This CL also fix the following platforms: * Change to always trusted: cyan. * Add to early GPIO table: dedede, eve, fizz, glados, hatch, octopus, poppy, reef, volteer. * Add to both Makefile and early GPIO table: zork. For mb/intel: * adlrvp: Add support for get_ec_is_trusted(). * glkrvp: Add support for get_ec_is_trusted() with always trusted. * kblrvp: Add support for get_ec_is_trusted() with always trusted. * kunimitsu: Add support for get_ec_is_trusted() and initialize it as early GPIO. * shadowmountain: Add support for get_ec_is_trusted() and initialize it as early GPIO. * tglrvp: Add support for get_ec_is_trusted() with always trusted. For qemu-q35: Add support for get_ec_is_trusted() with always trusted. We could attempt another land.

This reverts commit 6260bf712a836762b18d80082505e981e040f4bc. Reason for revert: This CL did not handle Intel GPIO correctly.

2021-09-16vboot_logic: Set VB2_CONTEXT_EC_TRUSTED in verstage_mainHsuan Ting Chen
vboot_reference is introducing a new field (ctx) to store the current boot mode in crrev/c/2944250 (ctx->bootmode), which will be leveraged in both vboot flow and elog_add_boot_reason in coreboot. In current steps of deciding bootmode, a function vb2ex_ec_trusted is required. This function checks gpio EC_IN_RW pin and will return 'trusted' only if EC is not in RW. Therefore, we need to implement similar utilities in coreboot. We will deprecate vb2ex_ec_trusted and use the flag, VB2_CONTEXT_EC_TRUSTED, in vboot, vb2api_fw_phase1 and set that flag in coreboot, verstage_main. Also add a help function get_ec_is_trusted which needed to be implemented per mainboard.

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.

Push clearing the recovery mode switch until after FSP code runs, so that a manual recovery request (three-finger salute) will function correctly under this condition. (2) The recovery mode switch value is needed at BS_WRITE_TABLES for adding an event to elog. (Previously this was done by stashing the value in CBMEM_ID_EC_HOSTEVENT.)

2019-11-20security/vboot: Remove selected_region from struct vboot_working_dataYu-Ping Wu
Since we already have pre-RAM cache for FMAP (CB:36657), calling load_firmware() multiple times is no longer a problem. This patch replaces vboot_get_selected_region() usage with vboot_locate_firmware(), which locates the firmware by reading from the CBMEM cache. In addition, returning false from vboot_is_slot_selected() implies the recovery path was requested, i.e., vb2_shared_data.recovery_reason was set. Therefore, we simply remove the vboot_is_slot_selected() check from vboot_check_recovery_request().

Two functions retrieve vboot recovery_reason: * vboot_handoff_get_recovery_reason * vboot_get_recovery_reason_shared_data Previously, when CBMEM comes online, a vboot_handoff data structure is created, and depending on the architecture, coreboot may eventually lose access to vboot_working_data. After implementing vboot_working_data CBMEM migration, vboot_working_data is always guaranteed to be accessible. vboot_get_recovery_reason_shared_data is corrected to also allow accessing vboot_working_data in ramstage and postcar. Now, vboot_handoff_get_recovery reason returning a valid recovery reason implies that vboot_get_recovery_reason_shared_data should *also* return a valid recovery reason. Thus we may remove the former.
