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