Subject: [PATCH 16/77] [build.sh,dts] added devicetree-Overlay

compile bpi-r2-mac.dts like this:

dtc -@ -I dts -O dtb -o bpi-r2-mac.dtb bpi-r2-mac.dts

in uboot you can load DTO with this (after loading base ftd):
loaddto=echo "loaddto:${dto}";fdt addr ${dtaddr};fdt resize 8192; setexpr fdtovaddr ${dtaddr} + F000;
  fatload ${device} ${partition} ${fdtovaddr} ${bpi}/${board}/${service}/dtb/${dto} && fdt apply ${fdtovaddr}

uboot needs option CONFIG_OF_LIBFDT_OVERLAY=y
