I think the DMA descriptors need to be 32 byte (0x20) aligned.
That's the reason the example application was set up like this.
But you can just as easily turn them into pointers which point to 32
byte aligned areas in a nocache region.
Just wondering if that's possible with the code because I think it
would be easier with the existing linkcmds to assign a nocache area as
you need and then split it by hand.

I would prefer to use a generic linker section definition and then
simply define global data structures in the right section with the right
alignment (see RTEMS_ALIGN()).
