/* BAFL Broadcom ARC Firmware Loader.
 * 
 * This module loads an optimized ELF image into memory for ARC processors.
 * An ELF image has been previousely been processed to remove unneeded 
 * symbol tables abd other ELF tables that are not needed. 
 *
 * The format of the resultant ELF files is as follows.
 *
 *------------------------------
 *       ELF Header            |

 * The format of the ELF image must be in this format for the BAFL_Load routine
 * to read the image linearly using the BIMG interface. This will prevent 
 * multiple copies from being perform which will result in a shorter load 
 * time.

 Summary:
  Enum used to specify ARC core boot mode.

 Description:
  This enum is used to determine if an ARC core boot is the result of a
  "normal" bootup sequence or the result of a watchdog restart.  The host
  may want to have a different boot/authentication sequence depending on
  the purpose of the reboot.  E.g. in watchdog mode, the security processor
  itself may not need re-configuration but the ARC itself may still need to
  be booted.
