 855  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 856  * stack that meets the minimum architecture alignment requirements for DMA.
 857  * Such a buffer is useful for DMA operations where flushing and invalidating
 858  * the cache before and after a read and/or write operation is required for
 859  * correct operations.
 860  *
 861  * When called the macro creates an array on the stack that is sized such
 862  * that:
 863  *
 864  * 1) The beginning of the array can be advanced enough to be aligned.
 865  *
 866  * 2) The size of the aligned portion of the array is a multiple of the minimum
 867  *    architecture alignment required for DMA.
 868  *
 869  * 3) The aligned portion contains enough space for the original number of
 870  *    elements requested.
 871  *
 872  * The macro then creates a pointer to the aligned portion of this array and
 873  * assigns to the pointer the address of the first element in the aligned
 874  * portion of the array.
 875  *
 876  * Calling the macro as:
 877  *
 878  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
 879  *
 880  * Will result in something similar to saying:
 881  *
 882  *     uint32_t    buffer[1024];
 883  *
 884  * The following differences exist:
 885  *
 886  * 1) The resulting buffer is guaranteed to be aligned to the value of
 887  *    ARCH_DMA_MINALIGN.
 888  *
 889  * 2) The buffer variable created by the macro is a pointer to the specified
 890  *    type, and NOT an array of the specified type.  This can be very important
 891  *    if you want the address of the buffer, which you probably do, to pass it
 892  *    to the DMA hardware.  The value of &buffer is different in the two cases.
 893  *    In the macro case it will be the address of the pointer, not the address
 894  *    of the space reserved for the buffer.  However, in the second case it
 895  *    would be the address of the buffer.  So if you are replacing hard coded
 896  *    stack buffers with this macro you need to make sure you remove the & from
 897  *    the locations where you are taking the address of the buffer.
 898  *
 899  * Note that the size parameter is the number of array elements to allocate,
 900  * not the number of bytes.
 901  *
 902  * This macro can not be used outside of function scope, or for the creation
 903  * of a function scoped static buffer.  It can not be used to create a cache
 904  * line aligned global buffer.
