  /*
   * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
   * stack that meets the minimum architecture alignment requirements for DMA.
   * Such a buffer is useful for DMA operations where flushing and invalidating
   * the cache before and after a read and/or write operation is required for
   * correct operations.
   *
   * When called the macro creates an array on the stack that is sized such
   * that:
   *
   * 1) The beginning of the array can be advanced enough to be aligned.
   *
   * 2) The size of the aligned portion of the array is a multiple of the minimum
   *    architecture alignment required for DMA.
   *
   * 3) The aligned portion contains enough space for the original number of
   *    elements requested.
   *
   * The macro then creates a pointer to the aligned portion of this array and
   * assigns to the pointer the address of the first element in the aligned
   * portion of the array.
   *
   * Calling the macro as:
   *
   *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
   *
   * Will result in something similar to saying:
   *
   *     uint32_t    buffer[1024];
   *
   * The following differences exist:
   *
   * 1) The resulting buffer is guaranteed to be aligned to the value of
   *    ARCH_DMA_MINALIGN.
   *
   * 2) The buffer variable created by the macro is a pointer to the specified
   *    type, and NOT an array of the specified type.  This can be very important
   *    if you want the address of the buffer, which you probably do, to pass it
   *    to the DMA hardware.  The value of &buffer is different in the two cases.
   *    In the macro case it will be the address of the pointer, not the address
   *    of the space reserved for the buffer.  However, in the second case it
   *    would be the address of the buffer.  So if you are replacing hard coded
   *    stack buffers with this macro you need to make sure you remove the & from
   *    the locations where you are taking the address of the buffer.
   *
   * Note that the size parameter is the number of array elements to allocate,
   * not the number of bytes.
   *
   * This macro can not be used outside of function scope, or for the creation
   * of a function scoped static buffer.  It can not be used to create a cache
   * line aligned global buffer.
