- *
- * Dynamic DMA mapping support.
- *
- * On RM200 there is no hardware dynamic DMA address translation,
- * so consistent alloc/free are merely page allocation/freeing.
- * The rest of the dynamic DMA mapping interface is implemented
- * in <asm/pci.h>.
- *
- * These routines assume that the RM has all it's memory at physical
- * addresses of < 512mb.
