 935  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the

 938  * the cache before and after a read and/or write operation is required for
 939  * correct operations.
 940  *
 941  * When called the macro creates an array on the stack that is sized such
 942  * that:
 943  *
 944  * 1) The beginning of the array can be advanced enough to be aligned.
 945  *
 946  * 2) The size of the aligned portion of the array is a multiple of the minimum
 947  *    architecture alignment required for DMA.
 948  *
 949  * 3) The aligned portion contains enough space for the original number of
 950  *    elements requested.
 951  *
 952  * The macro then creates a pointer to the aligned portion of this array and
 953  * assigns to the pointer the address of the first element in the aligned
 954  * portion of the array.

 962  *     uint32_t    buffer[1024];
 963  *
 964  * The following differences exist:
 965  *
 966  * 1) The resulting buffer is guaranteed to be aligned to the value of
 967  *    ARCH_DMA_MINALIGN.
 968  *
 969  * 2) The buffer variable created by the macro is a pointer to the specified
 970  *    type, and NOT an array of the specified type.  This can be very important
 971  *    if you want the address of the buffer, which you probably do, to pass it
 972  *    to the DMA hardware.  The value of &buffer is different in the two cases.
 973  *    In the macro case it will be the address of the pointer, not the address
 974  *    of the space reserved for the buffer.  However, in the second case it
 975  *    would be the address of the buffer.  So if you are replacing hard coded
 976  *    stack buffers with this macro you need to make sure you remove the & from
 977  *    the locations where you are taking the address of the buffer.
 978  *
 979  * Note that the size parameter is the number of array elements to allocate,
 980  * not the number of bytes.
 981  *
 982  * This macro can not be used outside of function scope, or for the creation
 983  * of a function scoped static buffer.  It can not be used to create a cache
 984  * line aligned global buffer.
