Re: [PATCH] pstore: Use root address-cells/size-cells as defaults for reserved-memory

u-boot adds reserve-memory node, if it's missing, with following properties:

    reserved-memory {
         #address-cells = <2>;
         #size-cells = <2>;
         ranges;
    }

But with these default address-cells and size-cells values, pstore isn't working on A64. Root node for A64 defines 'address-cells' and 'size-cells' as 1.

dtc complains if reserved-memory has different address-cells and size-cells.

     Warning (ranges_format): /reserved-memory:ranges: empty "ranges"
     property but its #address-cells (2) differs from / (1)

This patch takes into account address-cells and size-cells of the root node and uses them as values for new reserved-memory node.

Applied to u-boot/master, thanks!
