I've been thinking about doing just this for quite some time now. I've had a few informal discussions without people about. One idea is to allow attaching simple conditional expressions (like X is <, =, or > than Y) to a node. It is the responsibility of the code that parses the device tree to assign values to X and Y. For instance, they could be the names of U-Boot environment variables. If the expression is false, then the node is removed (or ignored) from the device tree. If it's true, then it's kept in. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
