Also, even though the ROUND macro is already defined in common.h, the reason for redefining it in image.h is explained by Stefano Babic: "I will remark a previous comment - even if including common.h seems a good idea to avoid duplications, it makes tools like mkimage to depend on the selected board, because <board>_config must run. Even if this is not a problem for us u-boot developers, it becomes an issue when these tools are included in distros (like u-boot-tools in Ubuntu) and cannot be packaged."
