975 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
976 * stack that meets the minimum architecture alignment requirements for DMA.
977 * Such a buffer is useful for DMA operations where flushing and invalidating
978 * the cache before and after a read and/or write operation is required for
979 * correct operations.
980 *
981 * When called the macro creates an array on the stack that is sized such
982 * that:
983 *
984 * 1) The beginning of the array can be advanced enough to be aligned.
985 *
986 * 2) The size of the aligned portion of the array is a multiple of the minimum
987 * architecture alignment required for DMA.
988 *
989 * 3) The aligned portion contains enough space for the original number of
990 * elements requested.
991 *
992 * The macro then creates a pointer to the aligned portion of this array and
993 * assigns to the pointer the address of the first element in the aligned
994 * portion of the array.
995 *
996 * Calling the macro as:
997 *
998 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
999 *
1000 * Will result in something similar to saying:
1001 *
1002 * uint32_t buffer[1024];
1003 *
1004 * The following differences exist:
1005 *
1006 * 1) The resulting buffer is guaranteed to be aligned to the value of
1007 * ARCH_DMA_MINALIGN.
1008 *
1009 * 2) The buffer variable created by the macro is a pointer to the specified
1010 * type, and NOT an array of the specified type. This can be very important
1011 * if you want the address of the buffer, which you probably do, to pass it
1012 * to the DMA hardware. The value of &buffer is different in the two cases.
1013 * In the macro case it will be the address of the pointer, not the address
1014 * of the space reserved for the buffer. However, in the second case it
1015 * would be the address of the buffer. So if you are replacing hard coded
1016 * stack buffers with this macro you need to make sure you remove the & from
1017 * the locations where you are taking the address of the buffer.
1018 *
1019 * Note that the size parameter is the number of array elements to allocate,
1020 * not the number of bytes.
1021 *
1022 * This macro can not be used outside of function scope, or for the creation
1023 * of a function scoped static buffer. It can not be used to create a cache
1024 * line aligned global buffer.
