The xSPI IP found on RZ/G3E SoC similar to RPC-IF interface, but it can support writes on memory-mapped area. Even though the registers are different, the rpcif driver code can be reused for xSPI by adding wrapper function to it. This patch series tested on RZ/G2L and RZ/G3E by overwriting boot partitions.
