consistent_alloc() on PPC

Hi , 
I am facing some problems porting my drivers to the PPC platform . Am
currently using consistent_alloc() and consistent_free() to
allocate/free (non-cached) DMA ble memory.
Is there any function/patch/macro, equivalent to
phy_to_virt()/virt_to_phy() for memory returned by consistent_alloc()?

Regards

Imo not.  I ended up writing a private version of it, along these
lines:

static inline unsigned long private_io_to_bus(void *addr)
{
        return iopa((unsigned long)addr) + offset;
}

Wouldn't hurt if you could generalize it somehow.
