Hello,
I am following up on this thread: "Merging device trees at runtime for module-based systems" http://lists.denx.de/pipermail/u-boot/2012-November/139618.html
I do not have a modular based system, so I do not need the full flexibility of merging DT fragments at runtime. However, I am very interested in being able to select a full DT from a list of DT's at runtime. I believe this is a degenerate case of the more general N x M modular case.
The background: I have a number of different platforms running u-boot. They all use the same Linux kernel and initramfs, but different DT.
What I would love is to have a single multi-file uImage I could use on all my platforms. The idea is to introduce a new image type that is a list of device tree blobs.
The uImage would contain a list of dtb's and u-boot would select the correct one at runtime. u-boot could iterate through the list inspecting the "model" property of the root node.
Thoughts on that approach?
Cheers, Curt
