    	[sskfile] secondary.pem 
    	[bootloader, authentication=rsa, aeskeyfile=encr_key.nky, encryption=aes] fsbl.elf

  new_bif:
  {
  	image
  	{
  		{ type = bootimage, file = base.pdi }
  	}
  	image
  	{
  		name = apu_ss, id = 0x1c000000
  	    { load = 0x1000, file = system.dtb }
           { exception_level = el-2, file = u-boot.elf }
           { core = a72-0, exception_level = el-3, trustzone, file = bl31.elf }
