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.
Resend with adding missed u-boot mailing list
Jagdish Gediya (8):
powerpc/dts: setup fdt blob at __init_end
powerpc/dts: makefile changes to clean and build dts
binman: Add a new "start-pos" property in section class
binman: Add support for powerpc 'bootpg + resetvec' entry
powerpc: mpc85xx: select BINMAN by default
powerpc: dts: add u-boot.dtsi and mpc85xx-u-boot.dtsi
powerpc: mpc85xx: Use binman to embed dtb inside u-boot
powerpc: dts: Enable device tree support for T2080QDS
