/**
|
|
* Initialize the system hardware.
|
|
* This function is responsible for putting the entire system to a state that
|
|
* 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).
