We need some name that means "U-Boot SPL with U-Boot tacked on at the end". This can optionally be padded to a defined size to make writing to hardware easier. We also have the problem that "u-boot.bin" already means something so it needs to be clear. I further fear that even if we made an "out" directory if we put u-boot.bin in there and it's not the same as the objcopy -O binary u-boot u-boot.bin as before we've violated the rule of least surprise and the end user problems from people that read "the" document (that happened to be out of date) will be our problem. In short, at least a few people have said something along the lines of "We need generic output nameo $mediums and targets" but there's two hard problems, one of which is that every SoC _needs_ things tweaked just so (no header? no boot!), sometimes wants things tweaked further (pad the final image out to be easier to write to $medium) and sometimes needs multiple files (the whole of 'SPL' will be read so it must fit into $SMALL_MEMORY). The other is naming. I don't want to block this series on this problem. I do want to say it needs to use my updated SPL framework or show that it's inadequate (and I owe another reply to part of this thread still) for this platform. Call it u-boot.s3c or .s3c24xx and lets continue talking about how to solve the general problem. -- Tom _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
