Another alternate approach could be to create one 'linux,usable-drconf-memory' property and add all the usable memory regions into it, in a similar fashion to ibm,dynamic-memory property. For a given lmb in ibm,dynamic-memory , a corresponding usable-memory entry could be created which will contain 1 or more of (base,size) duple. For each entry in this new 'linux,usable-drconf-memory' property, a counter within it will tell us how many (base,size) duple are available in it. Some part of the current code may get duplicated. Let me go back and check if I can work on a patch for this approach . thx, Chandru _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
