For the RZ/A series (and RZ/T series), it is called the
"SPI Multi I/O Bus Controller" (Chapter 17)
I have no idea why it has a different name for the same hardware (and
the same pages in the manual).
The HW version in RZ/A1 does not have HyperRAM.
But the HW version in RZ/A2 is the same as what is in R-Car Gen3.
