In current implementation, PowerPC does not support device tree in U-Boot. This patch enables device tree support for PowerPC platform .
T2080AQDS board used as first platform.
Dtb is embedded in the U-Boot following below steps using binmam tool.
1. Remove bootpg and resetvec section if required 2. Append dtb using binman 3. Append bootpg and resetvec section back if removed in 1st step.
To enable binman tool, 'binman' node has been added in the device tree.
