896 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
897 * stack that meets the minimum architecture alignment requirements for DMA.
898 * Such a buffer is useful for DMA operations where flushing and invalidating
899 * the cache before and after a read and/or write operation is required for
900 * correct operations.
901 *
902 * When called the macro creates an array on the stack that is sized such
903 * that:
904 *
905 * 1) The beginning of the array can be advanced enough to be aligned.
906 *
907 * 2) The size of the aligned portion of the array is a multiple of the minimum
908 * architecture alignment required for DMA.
909 *
910 * 3) The aligned portion contains enough space for the original number of
911 * elements requested.
912 *
913 * The macro then creates a pointer to the aligned portion of this array and
914 * assigns to the pointer the address of the first element in the aligned
915 * portion of the array.
916 *
917 * Calling the macro as:
918 *
919 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
920 *
921 * Will result in something similar to saying:
922 *
923 * uint32_t buffer[1024];
924 *
925 * The following differences exist:
926 *
927 * 1) The resulting buffer is guaranteed to be aligned to the value of
928 * ARCH_DMA_MINALIGN.
929 *
930 * 2) The buffer variable created by the macro is a pointer to the specified
931 * type, and NOT an array of the specified type. This can be very important
932 * if you want the address of the buffer, which you probably do, to pass it
933 * to the DMA hardware. The value of &buffer is different in the two cases.
934 * In the macro case it will be the address of the pointer, not the address
935 * of the space reserved for the buffer. However, in the second case it
936 * would be the address of the buffer. So if you are replacing hard coded
937 * stack buffers with this macro you need to make sure you remove the & from
938 * the locations where you are taking the address of the buffer.
939 *
940 * Note that the size parameter is the number of array elements to allocate,
941 * not the number of bytes.
942 *
943 * This macro can not be used outside of function scope, or for the creation
944 * of a function scoped static buffer. It can not be used to create a cache
945 * line aligned global buffer.
