 981  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 982  * stack that meets the minimum architecture alignment requirements for DMA.
 983  * Such a buffer is useful for DMA operations where flushing and invalidating
 984  * the cache before and after a read and/or write operation is required for
 985  * correct operations.
 986  *
 987  * When called the macro creates an array on the stack that is sized such
 988  * that:
 989  *
 990  * 1) The beginning of the array can be advanced enough to be aligned.
 991  *
 992  * 2) The size of the aligned portion of the array is a multiple of the minimum
 993  *    architecture alignment required for DMA.
 994  *
 995  * 3) The aligned portion contains enough space for the original number of
 996  *    elements requested.
 997  *
 998  * The macro then creates a pointer to the aligned portion of this array and
 999  * assigns to the pointer the address of the first element in the aligned
1000  * portion of the array.
1001  *
1002  * Calling the macro as:
1003  *
1004  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
1005  *
1006  * Will result in something similar to saying:
1007  *
1008  *     uint32_t    buffer[1024];
1009  *
1010  * The following differences exist:
1011  *
1012  * 1) The resulting buffer is guaranteed to be aligned to the value of
1013  *    ARCH_DMA_MINALIGN.
1014  *
1015  * 2) The buffer variable created by the macro is a pointer to the specified
1016  *    type, and NOT an array of the specified type.  This can be very important
1017  *    if you want the address of the buffer, which you probably do, to pass it
1018  *    to the DMA hardware.  The value of &buffer is different in the two cases.
1019  *    In the macro case it will be the address of the pointer, not the address
1020  *    of the space reserved for the buffer.  However, in the second case it
1021  *    would be the address of the buffer.  So if you are replacing hard coded
1022  *    stack buffers with this macro you need to make sure you remove the & from
1023  *    the locations where you are taking the address of the buffer.
1024  *
1025  * Note that the size parameter is the number of array elements to allocate,
1026  * not the number of bytes.
1027  *
1028  * This macro can not be used outside of function scope, or for the creation
1029  * of a function scoped static buffer.  It can not be used to create a cache
1030  * line aligned global buffer.
