905  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
906  * stack that meets the minimum architecture alignment requirements for DMA.
907  * Such a buffer is useful for DMA operations where flushing and invalidating
908  * the cache before and after a read and/or write operation is required for
909  * correct operations.
910  *
911  * When called the macro creates an array on the stack that is sized such
912  * that:
913  *
914  * 1) The beginning of the array can be advanced enough to be aligned.
915  *
916  * 2) The size of the aligned portion of the array is a multiple of the minimum
917  *    architecture alignment required for DMA.
918  *
919  * 3) The aligned portion contains enough space for the original number of
920  *    elements requested.
921  *
922  * The macro then creates a pointer to the aligned portion of this array and
923  * assigns to the pointer the address of the first element in the aligned
924  * portion of the array.
925  *
926  * Calling the macro as:
927  *
928  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
929  *
930  * Will result in something similar to saying:
931  *
932  *     uint32_t    buffer[1024];
933  *
934  * The following differences exist:
935  *
936  * 1) The resulting buffer is guaranteed to be aligned to the value of
937  *    ARCH_DMA_MINALIGN.
938  *
939  * 2) The buffer variable created by the macro is a pointer to the specified
940  *    type, and NOT an array of the specified type.  This can be very important
941  *    if you want the address of the buffer, which you probably do, to pass it
942  *    to the DMA hardware.  The value of &buffer is different in the two cases.
943  *    In the macro case it will be the address of the pointer, not the address
944  *    of the space reserved for the buffer.  However, in the second case it
945  *    would be the address of the buffer.  So if you are replacing hard coded
946  *    stack buffers with this macro you need to make sure you remove the & from
947  *    the locations where you are taking the address of the buffer.
948  *
949  * Note that the size parameter is the number of array elements to allocate,
950  * not the number of bytes.
951  *
952  * This macro can not be used outside of function scope, or for the creation
953  * of a function scoped static buffer.  It can not be used to create a cache
954  * line aligned global buffer.
