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().

2019-06-21vboot: remove vboot_handoff_get_recovery_reasonJoel Kitching
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.

Its spreading copies got out of sync. And as it is not a standard header but used in commonlib code, it belongs into commonlib. While we are at it, always include it via GCC's `-include` switch. Some Windows and BSD quirk handling went into the util copies. We always guard from redefinitions now to prevent further issues.
