because it does not have any dma operations.
Oh, it does work, with and without MMU, and is fully PIO based, no DMA or IRQ.
When I first wrote it for the linux kernel, it was already PIO based. I only
made a small port for barebox :)
The only thing which should be amended later is in the gadget layer, where g_serial.use_acm variable should be configurable by board code, but that's not related to any MMU issue.
Cheers.
