In the past the only thing the first number of a QorIQ chip name has meant is an approximate positioning on the low-end/high-end spectrum. It cannot be used for grouping chips according to anything that software cares about. > Probably it will be more generic to name it "fsl,scfg-msi" Better would have a specific SoC in the name. -Scott
