The SBE (Self Boot Engine) are on-chip microcontrollers that perform early boot steps, as well as provide some runtime facilities (e.g., timer, secure register access, MPIPL). The latter facilities are accessed mostly via a message system called SBEFIFO. This driver provides initial emulation for the SBE runtime registers and a very basic SBEFIFO implementation that provides the timer command. This covers the basic SBE behaviour expected by skiboot when booting.
