     13  Renesas RPC-IF allows a SPI flash or HyperFlash connected to the SoC to
     14  be accessed via the external address space read mode or the manual mode.
     15
     16  The flash chip itself should be represented by a subnode of the RPC-IF node.
     17  The flash interface is selected based on the "compatible" property of this
     18  subnode:
     19  - if it contains "jedec,spi-nor", then SPI is used;
     20  - if it contains "cfi-flash", then HyperFlash is used.
