  793. * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
  794. * stack that meets the minimum architecture alignment requirements for DMA.
  795. * Such a buffer is useful for DMA operations where flushing and invalidating
  796. * the cache before and after a read and/or write operation is required for
  797. * correct operations.
  798. *
  799. * When called the macro creates an array on the stack that is sized such
  800. * that:
  801. *
  802. * 1) The beginning of the array can be advanced enough to be aligned.
  803. *
  804. * 2) The size of the aligned portion of the array is a multiple of the minimum
  805. * architecture alignment required for DMA.
  806. *
  807. * 3) The aligned portion contains enough space for the original number of
  808. * elements requested.
  809. *
  810. * The macro then creates a pointer to the aligned portion of this array and
  811. * assigns to the pointer the address of the first element in the aligned
  812. * portion of the array.
  813. *
  814. * Calling the macro as:
  815. *
  816. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  817. *
  818. * Will result in something similar to saying:
  819. *
  820. * uint32_t buffer[1024];
  821. *
  822. * The following differences exist:
  823. *
  824. * 1) The resulting buffer is guaranteed to be aligned to the value of
  825. * ARCH_DMA_MINALIGN.
  826. *
  827. * 2) The buffer variable created by the macro is a pointer to the specified
  828. * type, and NOT an array of the specified type. This can be very important
  829. * if you want the address of the buffer, which you probably do, to pass it
  830. * to the DMA hardware. The value of &buffer is different in the two cases.
  831. * In the macro case it will be the address of the pointer, not the address
  832. * of the space reserved for the buffer. However, in the second case it
  833. * would be the address of the buffer. So if you are replacing hard coded
  834. * stack buffers with this macro you need to make sure you remove the & from
  835. * the locations where you are taking the address of the buffer.
  836. *
  837. * Note that the size parameter is the number of array elements to allocate,
  838. * not the number of bytes.
  839. *
  840. * This macro can not be used outside of function scope, or for the creation
  841. * of a function scoped static buffer. It can not be used to create a cache
  842. * line aligned global buffer.
