7 title: Renesas Reduced Pin Count Interface (RPC-IF)
10 - Sergei Shtylyov <sergei.shtylyov@gmail.com>
13 Renesas RPC-IF allows a SPI flash or HyperFlash connected to the SoC to
16 The flash chip itself should be represented by a subnode of the RPC-IF node.
19 - if it contains "jedec,spi-nor", then SPI is used;
20 - if it contains "cfi-flash", then HyperFlash is used.
