880  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
881  * stack that meets the minimum architecture alignment requirements for DMA.
882  * Such a buffer is useful for DMA operations where flushing and invalidating
883  * the cache before and after a read and/or write operation is required for
884  * correct operations.
885  *
886  * When called the macro creates an array on the stack that is sized such
887  * that:
888  *
889  * 1) The beginning of the array can be advanced enough to be aligned.
890  *
891  * 2) The size of the aligned portion of the array is a multiple of the minimum
892  *    architecture alignment required for DMA.
893  *
894  * 3) The aligned portion contains enough space for the original number of
895  *    elements requested.
896  *
897  * The macro then creates a pointer to the aligned portion of this array and
898  * assigns to the pointer the address of the first element in the aligned
899  * portion of the array.
900  *
901  * Calling the macro as:
902  *
903  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
904  *
905  * Will result in something similar to saying:
906  *
907  *     uint32_t    buffer[1024];
908  *
909  * The following differences exist:
910  *
911  * 1) The resulting buffer is guaranteed to be aligned to the value of
912  *    ARCH_DMA_MINALIGN.
913  *
914  * 2) The buffer variable created by the macro is a pointer to the specified
915  *    type, and NOT an array of the specified type.  This can be very important
916  *    if you want the address of the buffer, which you probably do, to pass it
917  *    to the DMA hardware.  The value of &buffer is different in the two cases.
918  *    In the macro case it will be the address of the pointer, not the address
919  *    of the space reserved for the buffer.  However, in the second case it
920  *    would be the address of the buffer.  So if you are replacing hard coded
921  *    stack buffers with this macro you need to make sure you remove the & from
922  *    the locations where you are taking the address of the buffer.
923  *
924  * Note that the size parameter is the number of array elements to allocate,
925  * not the number of bytes.
926  *
927  * This macro can not be used outside of function scope, or for the creation
928  * of a function scoped static buffer.  It can not be used to create a cache
929  * line aligned global buffer.
