1007 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
1008 * stack that meets the minimum architecture alignment requirements for DMA.
1009 * Such a buffer is useful for DMA operations where flushing and invalidating
1010 * the cache before and after a read and/or write operation is required for
1011 * correct operations.
1012 *
1013 * When called the macro creates an array on the stack that is sized such
1014 * that:
1015 *
1016 * 1) The beginning of the array can be advanced enough to be aligned.
1017 *
1018 * 2) The size of the aligned portion of the array is a multiple of the minimum
1019 * architecture alignment required for DMA.
1020 *
1021 * 3) The aligned portion contains enough space for the original number of
1022 * elements requested.
1023 *
1024 * The macro then creates a pointer to the aligned portion of this array and
1025 * assigns to the pointer the address of the first element in the aligned
1026 * portion of the array.
1027 *
1028 * Calling the macro as:
1029 *
1030 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
1031 *
1032 * Will result in something similar to saying:
1033 *
1034 * uint32_t buffer[1024];
1035 *
1036 * The following differences exist:
1037 *
1038 * 1) The resulting buffer is guaranteed to be aligned to the value of
1039 * ARCH_DMA_MINALIGN.
1040 *
1041 * 2) The buffer variable created by the macro is a pointer to the specified
1042 * type, and NOT an array of the specified type. This can be very important
1043 * if you want the address of the buffer, which you probably do, to pass it
1044 * to the DMA hardware. The value of &buffer is different in the two cases.
1045 * In the macro case it will be the address of the pointer, not the address
1046 * of the space reserved for the buffer. However, in the second case it
1047 * would be the address of the buffer. So if you are replacing hard coded
1048 * stack buffers with this macro you need to make sure you remove the & from
1049 * the locations where you are taking the address of the buffer.
1050 *
1051 * Note that the size parameter is the number of array elements to allocate,
1052 * not the number of bytes.
1053 *
1054 * This macro can not be used outside of function scope, or for the creation
1055 * of a function scoped static buffer. It can not be used to create a cache
1056 * line aligned global buffer.
