905 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
906 * stack that meets the minimum architecture alignment requirements for DMA.
907 * Such a buffer is useful for DMA operations where flushing and invalidating
908 * the cache before and after a read and/or write operation is required for
909 * correct operations.
910 *
911 * When called the macro creates an array on the stack that is sized such
912 * that:
913 *
914 * 1) The beginning of the array can be advanced enough to be aligned.
915 *
916 * 2) The size of the aligned portion of the array is a multiple of the minimum
917 * architecture alignment required for DMA.
918 *
919 * 3) The aligned portion contains enough space for the original number of
920 * elements requested.
921 *
922 * The macro then creates a pointer to the aligned portion of this array and
923 * assigns to the pointer the address of the first element in the aligned
924 * portion of the array.
925 *
926 * Calling the macro as:
927 *
928 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
929 *
930 * Will result in something similar to saying:
931 *
932 * uint32_t buffer[1024];
933 *
934 * The following differences exist:
935 *
936 * 1) The resulting buffer is guaranteed to be aligned to the value of
937 * ARCH_DMA_MINALIGN.
938 *
939 * 2) The buffer variable created by the macro is a pointer to the specified
940 * type, and NOT an array of the specified type. This can be very important
941 * if you want the address of the buffer, which you probably do, to pass it
942 * to the DMA hardware. The value of &buffer is different in the two cases.
943 * In the macro case it will be the address of the pointer, not the address
944 * of the space reserved for the buffer. However, in the second case it
945 * would be the address of the buffer. So if you are replacing hard coded
946 * stack buffers with this macro you need to make sure you remove the & from
947 * the locations where you are taking the address of the buffer.
948 *
949 * Note that the size parameter is the number of array elements to allocate,
950 * not the number of bytes.
951 *
952 * This macro can not be used outside of function scope, or for the creation
953 * of a function scoped static buffer. It can not be used to create a cache
954 * line aligned global buffer.
