 902  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 903  * stack that meets the minimum architecture alignment requirements for DMA.
 904  * Such a buffer is useful for DMA operations where flushing and invalidating
 905  * the cache before and after a read and/or write operation is required for
 906  * correct operations.
 907  *
 908  * When called the macro creates an array on the stack that is sized such
 909  * that:
 910  *
 911  * 1) The beginning of the array can be advanced enough to be aligned.
 912  *
 913  * 2) The size of the aligned portion of the array is a multiple of the minimum
 914  *    architecture alignment required for DMA.
 915  *
 916  * 3) The aligned portion contains enough space for the original number of
 917  *    elements requested.
 918  *
 919  * The macro then creates a pointer to the aligned portion of this array and
 920  * assigns to the pointer the address of the first element in the aligned
 921  * portion of the array.
 922  *
 923  * Calling the macro as:
 924  *
 925  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
 926  *
 927  * Will result in something similar to saying:
 928  *
 929  *     uint32_t    buffer[1024];
 930  *
 931  * The following differences exist:
 932  *
 933  * 1) The resulting buffer is guaranteed to be aligned to the value of
 934  *    ARCH_DMA_MINALIGN.
 935  *
 936  * 2) The buffer variable created by the macro is a pointer to the specified
 937  *    type, and NOT an array of the specified type.  This can be very important
 938  *    if you want the address of the buffer, which you probably do, to pass it
 939  *    to the DMA hardware.  The value of &buffer is different in the two cases.
 940  *    In the macro case it will be the address of the pointer, not the address
 941  *    of the space reserved for the buffer.  However, in the second case it
 942  *    would be the address of the buffer.  So if you are replacing hard coded
 943  *    stack buffers with this macro you need to make sure you remove the & from
 944  *    the locations where you are taking the address of the buffer.
 945  *
 946  * Note that the size parameter is the number of array elements to allocate,
 947  * not the number of bytes.
 948  *
 949  * This macro can not be used outside of function scope, or for the creation
 950  * of a function scoped static buffer.  It can not be used to create a cache
 951  * line aligned global buffer.
