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

Please consult adding these properties if they're not found with the
bootloader team using libfdt calls from there. All bl changes should
be self-contained.
I understand it won't be possible for released products, but hopefully
this could change for the next ones.
