896  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
897  * stack that meets the minimum architecture alignment requirements for DMA.
898  * Such a buffer is useful for DMA operations where flushing and invalidating
899  * the cache before and after a read and/or write operation is required for
900  * correct operations.
901  *
902  * When called the macro creates an array on the stack that is sized such
903  * that:
904  *
905  * 1) The beginning of the array can be advanced enough to be aligned.
906  *
907  * 2) The size of the aligned portion of the array is a multiple of the minimum
908  *    architecture alignment required for DMA.
909  *
910  * 3) The aligned portion contains enough space for the original number of
911  *    elements requested.
912  *
913  * The macro then creates a pointer to the aligned portion of this array and
914  * assigns to the pointer the address of the first element in the aligned
915  * portion of the array.
916  *
917  * Calling the macro as:
918  *
919  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
920  *
921  * Will result in something similar to saying:
922  *
923  *     uint32_t    buffer[1024];
924  *
925  * The following differences exist:
926  *
927  * 1) The resulting buffer is guaranteed to be aligned to the value of
928  *    ARCH_DMA_MINALIGN.
929  *
930  * 2) The buffer variable created by the macro is a pointer to the specified
931  *    type, and NOT an array of the specified type.  This can be very important
932  *    if you want the address of the buffer, which you probably do, to pass it
933  *    to the DMA hardware.  The value of &buffer is different in the two cases.
934  *    In the macro case it will be the address of the pointer, not the address
935  *    of the space reserved for the buffer.  However, in the second case it
936  *    would be the address of the buffer.  So if you are replacing hard coded
937  *    stack buffers with this macro you need to make sure you remove the & from
938  *    the locations where you are taking the address of the buffer.
939  *
940  * Note that the size parameter is the number of array elements to allocate,
941  * not the number of bytes.
942  *
943  * This macro can not be used outside of function scope, or for the creation
944  * of a function scoped static buffer.  It can not be used to create a cache
945  * line aligned global buffer.
