    1. Default environment will be used for secure boot flow
     which can't be edited or saved.
    2. Command for secure boot is predefined in the default
     environment which will run on autoboot (and autoboot is
     the only option allowed in case of secure boot) and it
     looks like this:
     #define CONFIG_SECBOOT \
     "setenv bs_hdraddr 0xe8e00000;"                 \
     "esbc_validate $bs_hdraddr;"                    \
     "source $img_addr;"                             \
     "esbc_halt;"
     #endif
    3. Boot Script can contain esbc_validate commands and bootm command.
     Uboot source command used in default secure boot command will
     run the bootscript.
    4. Command esbc_halt added to ensure either bootm executes
     after validation of images or core should just spin.
