+4. spiflash boot
+
+to enable device tree support for other boot, below configs need to be
+enabled in relative defconfig file,
+1. config_default_device_tree="t1024rdb" (change default device tree name if required)
+2. config_of_control
+3. config_mpc85xx_have_reset_vector if reset vector is located at
+   config_reset_vector_address - 0xffc
