 881  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 882  * stack that meets the minimum architecture alignment requirements for DMA.
 883  * Such a buffer is useful for DMA operations where flushing and invalidating
 884  * the cache before and after a read and/or write operation is required for
 885  * correct operations.
 886  *
 887  * When called the macro creates an array on the stack that is sized such
 888  * that:
 889  *
 890  * 1) The beginning of the array can be advanced enough to be aligned.
 891  *
 892  * 2) The size of the aligned portion of the array is a multiple of the minimum
 893  *    architecture alignment required for DMA.
 894  *
 895  * 3) The aligned portion contains enough space for the original number of
 896  *    elements requested.
 897  *
 898  * The macro then creates a pointer to the aligned portion of this array and
 899  * assigns to the pointer the address of the first element in the aligned
 900  * portion of the array.
 901  *
 902  * Calling the macro as:
 903  *
 904  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
 905  *
 906  * Will result in something similar to saying:
 907  *
 908  *     uint32_t    buffer[1024];
 909  *
 910  * The following differences exist:
 911  *
 912  * 1) The resulting buffer is guaranteed to be aligned to the value of
 913  *    ARCH_DMA_MINALIGN.
 914  *
 915  * 2) The buffer variable created by the macro is a pointer to the specified
 916  *    type, and NOT an array of the specified type.  This can be very important
 917  *    if you want the address of the buffer, which you probably do, to pass it
 918  *    to the DMA hardware.  The value of &buffer is different in the two cases.
 919  *    In the macro case it will be the address of the pointer, not the address
 920  *    of the space reserved for the buffer.  However, in the second case it
 921  *    would be the address of the buffer.  So if you are replacing hard coded
 922  *    stack buffers with this macro you need to make sure you remove the & from
 923  *    the locations where you are taking the address of the buffer.
 924  *
 925  * Note that the size parameter is the number of array elements to allocate,
 926  * not the number of bytes.
 927  *
 928  * This macro can not be used outside of function scope, or for the creation
 929  * of a function scoped static buffer.  It can not be used to create a cache
 930  * line aligned global buffer.
