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