/* State machine */
Both component of Bootloader, it is to say SPI_MASTER and SDRAM_FAT32_LOADER components, does use several state-machines, one state-machine per process, each process communicating with another one using "MASTER/SLAVE" : the master state-machine does ask a slave to do something, and slave does notify master when its task is finished.
Theses state-machines does use led debug : an integer contains the state of state machine, and this integer is displayed on 8 leds so you know where you are, it's for that I add several crash states in order to understand why and where component does crash. In MiST-board, this is displayed on the five 7-segment I added in OSD, I add also a input in order to select one or another state machine.
