AIUI the mp kernel flavour is for armhf (armv7) only, whereas the dreamplug is armel (v5). I don't know about APPENDED_DTB on armhf. I suppose armv7 platforms are much more likely to support fdt in their u-boot. The main danger with CONFIG_ARM_APPENDED_DTB is that there might, by coincidence, happen to be something which looks like a DTB in the memory right after where the kernel is. If for some reason we find ourselves compelled to enable that option then teaching bootloaders to zero a few bytes after the kernel is one option, as is teaching e.g. flash-kernel to append a few zeroes to the image. It also seems like it ought to be possible to replace any use of CONFIG_ARM_APPENDED_DTB with a devio shim. I think that sounds preferable since it confines the pain to the platforms with the shortcomings... Ian. -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
