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.
