Correct. More or less.
Of the 3 devices (RZ/A1, RZ/A2, R-Car), RZ/A1 only supported SPI.
RZ/A2 and R-Car now support SPI and HyperFlash.
But in my laziness, I never upstreamed the RZ/A1 driver 2 year ago...so here we are :)

I'm trying to figure out if the differences are 'technical' or
'ideological' (ie, R-Car use cases vs RZ use cases).
Of course we can do anything we want in our vendor BSPs, but I'd like
to see a common upstream path.
