Actually AMBA has generalized past being ARM-specific.
It's just a chip-internal bus, and the silicon-IP
end of ARM Ltd has been successful enough that vendors
use it with non-ARM CPUs too.
Example: you'll notice that drivers/dma/dw_dmac.c was
first used on a non-ARM system; it's a Synopsys DesignWare
(dw) DMA controller (dmac) for AMBA2, with AHB and APB.
So let me suggest LKML, with an FYI to the ARM list,
and putting that driver in drivers/dma instead. :)
But yes, now I see what you mean: discrete DMA and SPI
drivers.
