Note that U-Boot is always chainloaded from cboot starting with L4T release 28. cboot always loads U-Boot to a fixed address, so making the builds position independent isn't strictly necessary. However, position independent builds can be convenient because if U-Boot is ever loaded to an address different from its link address, it will still be able to boot.
