That's what I was wondering about. Is this really a good idea? Effectively, in the Linux kernel the device tree is being used as a big blob of initdata, except that it cannot free the memory allocated by the device tree when it is complete. As it is right now, device trees seem to weigh in between 4-8kB, a pretty insignificant size for memory that cannot be reclaimed. However, if firmware blobs start getting added to the tree that size could balloon pretty quickly. I'm not actually opposed to the feature, and I understand that it is needed for the new u-boot image format, but I think we need some usage guidelines in place when this feature is merged. As much as possible I think we should be directing developers to use the existing firmware loading facilities in the Linux kernel. Cheers, g. -- Grant Likely, B.Sc., P.Eng.
