 966 /*
 967  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 968  * stack that meets the minimum architecture alignment requirements for DMA.
 969  * Such a buffer is useful for DMA operations where flushing and invalidating
 970  * the cache before and after a read and/or write operation is required for
 971  * correct operations.
 972  *
 973  * When called the macro creates an array on the stack that is sized such
 974  * that:
 975  *
 976  * 1) The beginning of the array can be advanced enough to be aligned.
 977  *
 978  * 2) The size of the aligned portion of the array is a multiple of the minimum
 979  *    architecture alignment required for DMA.
 980  *
 981  * 3) The aligned portion contains enough space for the original number of
 982  *    elements requested.
 983  *
 984  * The macro then creates a pointer to the aligned portion of this array and
 985  * assigns to the pointer the address of the first element in the aligned
 986  * portion of the array.
 987  *
 988  * Calling the macro as:
 989  *
 990  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
 991  *
 992  * Will result in something similar to saying:
 993  *
 994  *     uint32_t    buffer[1024];
 995  *
 996  * The following differences exist:
 997  *
 998  * 1) The resulting buffer is guaranteed to be aligned to the value of
 999  *    ARCH_DMA_MINALIGN.
1000  *
1001  * 2) The buffer variable created by the macro is a pointer to the specified
1002  *    type, and NOT an array of the specified type.  This can be very important
1003  *    if you want the address of the buffer, which you probably do, to pass it
1004  *    to the DMA hardware.  The value of &buffer is different in the two cases.
1005  *    In the macro case it will be the address of the pointer, not the address
1006  *    of the space reserved for the buffer.  However, in the second case it
1007  *    would be the address of the buffer.  So if you are replacing hard coded
1008  *    stack buffers with this macro you need to make sure you remove the & from
1009  *    the locations where you are taking the address of the buffer.
1010  *
1011  * Note that the size parameter is the number of array elements to allocate,
1012  * not the number of bytes.
1013  *
1014  * This macro can not be used outside of function scope, or for the creation
1015  * of a function scoped static buffer.  It can not be used to create a cache
1016  * line aligned global buffer.
