Yes, CHRP had PC-style floppy controllers. And decent South Bridges used on PPC
(e.g. W53C883) usually support 32-bit ISA DMA.
The South Bridge on the "AmigaOne" is a VIA686B. It's a common PC
component, and it implements an i8259 ISA DMA controller, which can't do
DMA above 16MB.
I think it _might_ have an option for 32 Bit ISA DMA, but due to the
docs being so poor, and no other information being available, it's
probably easier to do what I believe x86 Linux does on similar hardware
- use ISA DMA below 16MB only.
