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