In the hardware manuals, it is almost always labeled as the "Renesas SPI Multi I/O Bus Controller". However, the HW IP is usually referred to within Renesas as the "SPIBSC" block. This driver has been tested on an RZ/A1H RSK and RZ/A2M EVB. The testing mostly consisted of formatting an area as JFFS2 and doing copying of files and such. While the HW changed a little between the RZ/A1 and RZ/A2 generations, the IP block in the RZ/A2M was taken from the R-Car H3 design, so in theory this driver should work for R-Car Gen3 as well.
