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