That would mean I cannot reuse the code in dma-mapping.c, right?
Sure you can. All you need to do is turn of BAT mapping, which
is as easy as using the 'nobats' command line parameter and
all of this code should just work for you.
... but I guess I have to setup my own page table for the reserved
DMA memory area and implement my own alloc_pages() function!?
No, that's already done for you behind all of these functions.
Thanks.
