however this got missed in between, so sending it across again.

If you're not adding a partition table, you can drop the address-
and size-cells properties, as they determine what the reg value of
the child looks like.


Sorry, somehow I missed this query. Will check and update it.


Currently IPQ boot loaders patches the partition information into the SPI node. To parse that, we need the address-cells and size-cells properties.

Also, this patch is now integrated into the below series
