//! Possible boot modes.

// TODO: b/312605899 - find full list of supported boot modes
// Looks like we need only compliant items from map: system/core/bootstat/bootstat.cpp
// kBootReasonMap
// It might be required to assemble this type in format: <reason>,<sub_reason>,<detil>,...
// Bootloaders must provide a kernel set or a blunt set reason, and are strongly encouraged to
// provide a subreason if it can be determined. For example, a power key long press that may or may
// not have ramoops backup would have the boot reason "reboot,longkey".
