I suspect what you want is

        dma-ranges = <0x80000000 0 0x80000000>;

to translate dma_addr_t 0x80000000-0xffffffff to phys_addr_t 0x0-0x7fffffff
rather than phys_addr_t 0x800000000-0x87fffffff.

Interesting. Where does the ROM address space resides on integrator then considering
address 0 is used for DMA.

The ROM is at physical address 0x20000000, don't ask me
why :-)

The RAM is typically at 0x00000000-0x0fffffff, on up to four parallell
tiles, i.e. up to four completely independent CPUs are booted off the
same ROM and using a set of shared peripherals.

Thanks, I'll fix up my patch.

Feel free to add my ack after the fixup if you need one.

Thanks!

Yours,
