Hmmm, so all the dtbs get built, trouble is we need to specify which dtb gets used by SPL. This is why the DEFAULT_DEVICE_TREE gets set. A solution to do what you're asking is to have a dtb in SPL that works for all socs (dl/qp/q) for each board (sabreauto/sabresd). I'm afraid it might get too big to fit in sram. I'll give it a try tomorrow. As for the u-boot proper, in order to have one u-boot.itb file that works on all socs we need to support MULTI_FIT in u-boot proper and make u-boot chose from the fit table the right dtb. I'll try to do that for the next version of this patchset. I'll keep you up to date with the development. _______________________________________________ U-Boot mailing list [email protected] https://lists.denx.de/listinfo/u-boot
