915  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
916  * stack that meets the minimum architecture alignment requirements for DMA.
917  * Such a buffer is useful for DMA operations where flushing and invalidating
918  * the cache before and after a read and/or write operation is required for
919  * correct operations.
920  *
921  * When called the macro creates an array on the stack that is sized such
922  * that:
923  *
924  * 1) The beginning of the array can be advanced enough to be aligned.
925  *
926  * 2) The size of the aligned portion of the array is a multiple of the minimum
927  *    architecture alignment required for DMA.
928  *
929  * 3) The aligned portion contains enough space for the original number of
930  *    elements requested.
931  *
932  * The macro then creates a pointer to the aligned portion of this array and
933  * assigns to the pointer the address of the first element in the aligned
934  * portion of the array.
935  *
936  * Calling the macro as:
937  *
938  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
939  *
940  * Will result in something similar to saying:
941  *
942  *     uint32_t    buffer[1024];
943  *
944  * The following differences exist:
945  *
946  * 1) The resulting buffer is guaranteed to be aligned to the value of
947  *    ARCH_DMA_MINALIGN.
948  *
949  * 2) The buffer variable created by the macro is a pointer to the specified
950  *    type, and NOT an array of the specified type.  This can be very important
951  *    if you want the address of the buffer, which you probably do, to pass it
952  *    to the DMA hardware.  The value of &buffer is different in the two cases.
953  *    In the macro case it will be the address of the pointer, not the address
954  *    of the space reserved for the buffer.  However, in the second case it
955  *    would be the address of the buffer.  So if you are replacing hard coded
956  *    stack buffers with this macro you need to make sure you remove the & from
957  *    the locations where you are taking the address of the buffer.
958  *
959  * Note that the size parameter is the number of array elements to allocate,
960  * not the number of bytes.
961  *
962  * This macro can not be used outside of function scope, or for the creation
963  * of a function scoped static buffer.  It can not be used to create a cache
964  * line aligned global buffer.
