So what we want to know here is whether this is a general-purpose
SPI block, or if it's a special-purpose SPI block that can only be
used for accessing flashes.

If it's the former that part should be broken out into drivers/spi
of course...

But the register map seems a bit special-purpose so it could
very well be that this is for flash control only. So maybe you can
spill some beans from a datasheet here?

A clock divider at offset 0x10 already tells us that this is probably
a PL022 derivate, just that we don't know how much it has
been hacked with... does this thing contain AMBA identifiers
at the end of the IO-region, usually at 0x0fe0 thru 0x0fff?
