.. code-block:: none

   Nordic Owned Partitions

   Memory partition table with permission attributes common to its partitions.
   This is a special case of the Nordic Owned Memory binding.

   Every compatible node is expected to be a child of a memory node, where the
   listed partitions belong.

   A single memory node can contain multiple partition tables, each with a
   different set of permissions. For each such table, the smallest memory region
   spanning the contained partitions will be recorded in the UICR. These regions
   are allowed to contain gaps between the partitions, but this is discouraged.

   Example:

     mram1x: mram@e000000 {
         compatible = "nordic,mram";
         reg = <0xe000000 0x200000>;
         ...

         rx-partitions {
             compatible = "nordic,owned-partitions";
             perm-read;
             perm-execute;
             #address-cells = <1>;
             #size-cells = <1>;

             slot0_partition: partition@c0000 {
                 label = "image-0";
                 reg = <0xc0000 0x40000>;
             };
         };

         rw-partitions {
             compatible = "nordic,owned-partitions";
             perm-read;
             perm-write;
             #address-cells = <1>;
             #size-cells = <1>;

             slot1_partition: partition@100000 {
                 label = "image-1";
                 reg = <0x100000 0x50000>;
             };
             storage_partition: partition@150000 {
                 label = "storage";
                 reg = <0x150000 0x6000>;
             };
         };
     };

   From this example, two memory regions will be inferred:

     - 0x0E0C0000--0x0E100000, with read & execute permissions, containing the
       partition labeled "image-0".
     - 0x0E100000--0x0E156000, with read & write permissions, containing the
       partitions labeled "image-1" and "storage".
