Yes! > How many boards do we realistically support and need to test? How many *.dtb files to we build where we don't care? I guess we should "have" a tool that creates a full build of all dtb files over all architectures we have that use FDT and populate a directory with them. Do the same with new import DTS. Then have another tool that decompiles and compares the trees, abstracting away any systematic differences and create a readable diff. Most of the time when things break some nodes have been moved or been renamed. We need to adjust the driver frontends in that case. This should be fairly easy to spot in the diffs. Practically it will be impossible to avoid breakage - let's do it in -current and do it early, then call for testing by anyone with hardware. Martin
