[PATCH 0/8] Add RZ/G3E xSPI support

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

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.

Biju Das (8):
  dt-bindings: memory: Document RZ/G3E support
  memory: renesas-rpc-if: Move rpc-if reg definitions
  memory: renesas-rpc-if: Use devm_reset_control_array_get_exclusive()
  memory: renesas-rpc-if: Move rpcif_info definitions near to the user
  memory: renesas-rpc-if: Add regmap to struct rpcif_info
  memory: renesas-rpc-if: Add wrapper functions
  memory: renesas-rpc-if: Add RZ/G3E xSPI support
  spi: rpc-if: Add write support for memory-mapped area
