Why is U-Boot needed?

U-Boot (speaking of bootloaders in general) then configures a minimal set of devices, memory, chip settings, etc., to enable the main OS to be loaded and started. The main OS init takes care of any additional configuration or initialization. So the sequence is: Processor power-on or reset.
