Yeah, most definitely under construction. Keep? Maybe reference the Intel docs instead. ¯\_(ツ)_/¯

Board Support Package (BSP)

The BSP is essential code that will make the HPS device work with the computer's OS (operating system). The BSP contains a small program called a boot loader or boot manager that places the OS and device drivers into memory. The contents/components of the BSP depend on the particular hardware and OS.

Specific tasks that the BSP performs include the following, in order:

• Initialize the processor.
• Initialize the bus.
• Initialize the interrupt controller.
• Initialize the clock.
• Initialize the RAM (random access memory) settings.
• Configure the segments (if applicable).
• Run the boot loader.
• In addition to the foregoing, a BSP can contain directives, compilation parameters, and hardware parameters for configuring the OS.
