No, you don't read it correctly. What we call "shutdown" function is a
function that is used to shut down the flashing process, so it is a wake
up function for the EC that had to be shut down when we initialized the
flashing process.

You put the b4/ff/read sequence into the board_enable function, and
register a shutdown function that sends fb/ff.
