6.4.4. Preloader Handoff Information

The system manager provides ten 32-bit registers to store handoff information between the preloader and the operating system. The preloader can store any information in these registers. These register contents have no impact on the state of the HPS hardware. When the operating system kernel boots, it retrieves the information by reading the preloader to OS handoff information register array. These registers are reset only by a cold reset.
