939 /*
940 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
941 * stack that meets the minimum architecture alignment requirements for DMA.
942 * Such a buffer is useful for DMA operations where flushing and invalidating
943 * the cache before and after a read and/or write operation is required for
944 * correct operations.
945 *
946 * When called the macro creates an array on the stack that is sized such
947 * that:
948 *
949 * 1) The beginning of the array can be advanced enough to be aligned.
950 *
951 * 2) The size of the aligned portion of the array is a multiple of the minimum
952 * architecture alignment required for DMA.
953 *
954 * 3) The aligned portion contains enough space for the original number of
955 * elements requested.
956 *
957 * The macro then creates a pointer to the aligned portion of this array and
958 * assigns to the pointer the address of the first element in the aligned
959 * portion of the array.
960 *
961 * Calling the macro as:
962 *
963 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
964 *
965 * Will result in something similar to saying:
966 *
967 * uint32_t buffer[1024];
968 *
969 * The following differences exist:
970 *
971 * 1) The resulting buffer is guaranteed to be aligned to the value of
972 * ARCH_DMA_MINALIGN.
973 *
974 * 2) The buffer variable created by the macro is a pointer to the specified
975 * type, and NOT an array of the specified type. This can be very important
976 * if you want the address of the buffer, which you probably do, to pass it
977 * to the DMA hardware. The value of &buffer is different in the two cases.
978 * In the macro case it will be the address of the pointer, not the address
979 * of the space reserved for the buffer. However, in the second case it
980 * would be the address of the buffer. So if you are replacing hard coded
981 * stack buffers with this macro you need to make sure you remove the & from
982 * the locations where you are taking the address of the buffer.
983 *
984 * Note that the size parameter is the number of array elements to allocate,
985 * not the number of bytes.
986 *
987 * This macro can not be used outside of function scope, or for the creation
988 * of a function scoped static buffer. It can not be used to create a cache
989 * line aligned global buffer.
