Maybe we could make the dma_addr_t size configurable (and disabled by

It would be far better to fix the dma_addr_t abuses.  I've already fixed
those in the pl08x driver:

struct lli {
        dma_addr_t src;
        dma_addr_t dst;
        dma_addr_t next;
        u32 cctl;
};

became:

struct pl08x_lli {
        u32 src;
        u32 dst;
        u32 lli;
        u32 cctl;
};

and similar needs to be done elsewhere in ARM specific drivers.
dma_addr_t has no business being in structures that describe data which
hardware accesses.
