    [ARM] remove a common set of __virt_to_bus definitions · b5ee9002
    Nicolas Pitre authored
    Let's provide an overridable default instead of having every machine
    class define __virt_to_bus and __bus_to_virt to the same thing.  What
    most platforms are using is bus_addr == phys_addr so such is the default.
    
    One exception is ebsa110 which has no DMA what so ever, so the actual
    definition is not important except only for proper compilation.  Also
    added a comment about the special footbridge bus translation.
    
    Let's also remove comments alluding to set_dma_addr which is not
    (and should not) be commonly used.
