Mips Magnum has a floppy disk controller which is memory-mapped. It is=20
connected to jazz IRQ controller (works in Qemu) and to jazz DMA=20
controller (not done in Qemu). The problem I'm still facing is that it=20
is intimately linked with i8257 DMA engine, and I wasn't able to easily=20
decouple them.
