Device tree support and how to enable it for different configs
--------------------------------------------------------------
Device tree support is available for t2080rdb 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="t2080rdb" (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
If device tree support is enabled in defconfig,
1. use 'u-boot-with-dtb.bin' for NOR boot.
2. use 'u-boot-with-spl-pbl.bin' for other boot.
