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?
