Ok, so let's put the JEDEC SPD data in the device tree then. But I fail to see how that changes the "split"? There's still two sources of configuration, one from firmware used at boot and one from a data structure that the kernel uses. I do think sticking to an existing well-defined data structure such as SPD data is to be preferred over doing an open-coded new binding. This way, some platforms that might or might not have SPD in hardware can use the same code paths (i.e. a board that has memory on a DIMM instead of soldered down, or that uses soldered-down SPD). -Olof _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
