 * allows the Kernel to perform its bootstrap procedure and is therefore the
 * first thing to be called by `do_bootstrap`.  Possible tasks to be dealt with
 * here include:
 *
 * - Performing sanity checks to see if there are any major hardware faults
 * - Setting up the CPU frequency and other oscillators
 * - Communicating that frequency change to any hardware component that needs
 *   to know about it (especially the flash controller)
 * - Enabling interrupts that are vital for stable operation
 *
 * If any of this fails, an on-chip LED should be used to "morse" some kind of
 * diagnostic message, if the system has one (kind of like BIOS beep codes).
