+Device tree support is available for p2041rdb for below mentioned boot,
+1. NOR Boot
+2. NAND Boot
+3. SD Boot
+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="p2041rdb" (Change default device tree name if required)
+2. CONFIG_OF_CONTROL
+3. CONFIG_MPC85XX_HAVE_RESET_VECTOR if reset vector is located at

+
+If device tree support is enabled in defconfig, use 'u-boot-with-dtb.bin'
+instead of u-boot.bin for all boot.
