860  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
861  * stack that meets the minimum architecture alignment requirements for DMA.
862  * Such a buffer is useful for DMA operations where flushing and invalidating
863  * the cache before and after a read and/or write operation is required for
864  * correct operations.
865  *
866  * When called the macro creates an array on the stack that is sized such
867  * that:
868  *
869  * 1) The beginning of the array can be advanced enough to be aligned.
870  *
871  * 2) The size of the aligned portion of the array is a multiple of the minimum
872  *    architecture alignment required for DMA.
873  *
874  * 3) The aligned portion contains enough space for the original number of
875  *    elements requested.
876  *
877  * The macro then creates a pointer to the aligned portion of this array and
878  * assigns to the pointer the address of the first element in the aligned
879  * portion of the array.
880  *
881  * Calling the macro as:
882  *
883  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
884  *
885  * Will result in something similar to saying:
886  *
887  *     uint32_t    buffer[1024];
888  *
889  * The following differences exist:
890  *
891  * 1) The resulting buffer is guaranteed to be aligned to the value of
892  *    ARCH_DMA_MINALIGN.
893  *
894  * 2) The buffer variable created by the macro is a pointer to the specified
895  *    type, and NOT an array of the specified type.  This can be very important
896  *    if you want the address of the buffer, which you probably do, to pass it
897  *    to the DMA hardware.  The value of &buffer is different in the two cases.
898  *    In the macro case it will be the address of the pointer, not the address
899  *    of the space reserved for the buffer.  However, in the second case it
900  *    would be the address of the buffer.  So if you are replacing hard coded
901  *    stack buffers with this macro you need to make sure you remove the & from
902  *    the locations where you are taking the address of the buffer.
903  *
904  * Note that the size parameter is the number of array elements to allocate,
905  * not the number of bytes.
906  *
907  * This macro can not be used outside of function scope, or for the creation
908  * of a function scoped static buffer.  It can not be used to create a cache
909  * line aligned global buffer.
