  41        Kernel will compare hash values to check if
  42        the loaded program are exact as what you expect
  43        To ensure the hash value you fill is right.
  44        The steps to obtain hash value are listed below;
  45
  46            (1) Turn off SBCHK_BASE_HASH_CHECK
  47            (2) Download images and record kernel log
  48            (3) Find the string pattern '[SBCHK_BASE]' in kernel log
  49            (4) The hash value of '/system/bin/sbchk' is calculated
  50                [SBCHK_BASE] Calculate the hash value of '/system/bin/sbchk' =
  51                xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  52            (5) Fill hash value in SBCHK_ENGINE_HASH
  53            (6) The hash value of '/system/lib/modules/sec.ko' is calculated
  54                [SBCHK_BASE] Calculate the hash value of '/system/lib/modules/sec.ko' =
  55                xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  56            (7) Fill hash value in SBCHK_MODULE_HASH
  57            (8) The hash value of '/system/lib/modules/ccci.ko' is calculated
  58                [SBCHK_BASE] Calculate the hash value of '/system/lib/modules/ccci.ko' =
  59                xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  60            (9) Fill hash value in MODEM_CORE_MODULE_HASH
  61            (10) The hash value of '/system/lib/modules/ccci_plat.ko' is calculated
  62                [SBCHK_BASE] Calculate the hash value of '/system/lib/modules/ccci_plat.ko' =
  63                xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  64            (11) Fill hash value in MODEM_PLAT_MODULE_HASH
  65            (12) The hash value of 'init.rc' is calculated
  66                [SBCHK_BASE] Calculate the hash value of 'init.rc' =
  67                xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
  68            (13) Fill hash value in INIT_RC_HASH
  69
  70        PLEASE NOTE THAT !!!!!!
  71        The hash value may be changed if compile tool chain is updated or customer modify this user space program
  72        Before delivering boot image, please double check if the hash value should be updated or not.
