[U-Boot] 4K padding of ARM DT blob

[Yehuda Yitschak]

Hey Tom 

In arch/arm/dts/Makfile: line 56 
"DTC_FLAGS += -R 4 -p 0x1000"

this tell the dtc tool to add a 4K padding to the device tree blob. 

i can't figure out why this is needed.
Its creating a 4KB penalty on the dtb file so i guess it has some justification. 

Thanks 

Yehuda

Can you expand on what you're referring to / code in question?  Thanks!
