Any particular reason to special-case it, when we already need code to do it the other way for every other fsl soc? > On mpc82xx-pq2 we could > add a immr "device" to search for. Enh. The soc node *is* the immr "device". I'd rather add a node for the "initial" registers (they generally don't involve configuring the immr "bus" itself, but rather the chipselect bus and other miscellaneous things) if needed, get rid of /soc/reg, and have ranges cover the whole immr. And why is 82xx-pq2 special? Wouldn't you need this on 83xx, 85xx, and 86xx as well? -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
