// Description: This header file defines device structures and constant related
//              to boot configuration. BOOT_CFG structure defines layout of
//              persistent device information. It is used to control boot
//              process. BSP_ARGS structure defines information passed from
//              boot loader to kernel HAL/OAL. Each structure has version
//              field which should be updated each time when structure layout
//              change.
