Ah, this explains a lot. Thanks for this explanation. Um... do you have any plans how to handle this in a clean way that will scale for additional SoCs and boards as well, and that eventually can be used for other architectures, too? I guess you will have to address the same issues in your Linux ports? Do you consider using the device tree to implement the capability to adjust the software configuration to the specifics of the current hardware? I think this would be really beneficial both for U-Boot and Linux. I have to admit that I'm pretty much stuck between a rock and a hard place. I highly appreciate the fact that Samsung starts contributing code to Linux and now also U-Boot mainline trees,. and as such I want to encourage you all as much as possible, and not put any road blocks in your way when it can be avoided. I already hesitated when I rejected all these base address plus offset things and demanded these to be changed to C structs. I am well aware that is causes a lot of effort on your side without any immediately visible benefit (your code is already running, so why change it?). On the other hand, I have to keep an eye at the overall code quality, and to make sure the coderemains maintenable. >From the patches I've seen so far I fear that we weill quickly see the code copmplexity explode when it comes to handling different SoC and board combinations within a single U-Boot image. I would like to point out that we should not go the way that is currently being used in the ARM Linux kernel. We will not duplicate the MACH_ID concepts used there and the resulting code methods. Instead, when we need to add such flexible configuration, we will go the device tree way. I hope such comment still comes in time to help you taking the right turns.
