579 * This function will advance the firmware into boot stage 3 from boot stage 2.
580 * Boot stage 3 is required to send commands to the firmware. This is achieved
581 * by setting the firmware NEED configuration register to zero, this indicates
582 * no configuration is required forcing the firmware to advance to boot stage 3.
584 * Later revisions of the firmware require the use of an alternative register
610 * This function will return the firmware to boot stage 2 from boot stage 3.
611 * Boot stage 2 is required to apply updates to the firmware. This is achieved
612 * by setting the firmware NEED configuration register to FW_PATCH_NEED_CFG,
614 * firmware will see it is missing a patch configuration and will pause in boot
618 * register here as the driver will only return to boot stage 2 if the firmware
