 891  * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
 892  * stack that meets the minimum architecture alignment requirements for DMA.
 893  * Such a buffer is useful for DMA operations where flushing and invalidating
 894  * the cache before and after a read and/or write operation is required for
 895  * correct operations.
 896  *
 897  * When called the macro creates an array on the stack that is sized such
 898  * that:
 899  *
 900  * 1) The beginning of the array can be advanced enough to be aligned.
 901  *
 902  * 2) The size of the aligned portion of the array is a multiple of the minimum
 903  *    architecture alignment required for DMA.
 904  *
 905  * 3) The aligned portion contains enough space for the original number of
 906  *    elements requested.
 907  *
 908  * The macro then creates a pointer to the aligned portion of this array and
 909  * assigns to the pointer the address of the first element in the aligned
 910  * portion of the array.
 911  *
 912  * Calling the macro as:
 913  *
 914  *     ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
 915  *
 916  * Will result in something similar to saying:
 917  *
 918  *     uint32_t    buffer[1024];
 919  *
 920  * The following differences exist:
 921  *
 922  * 1) The resulting buffer is guaranteed to be aligned to the value of
 923  *    ARCH_DMA_MINALIGN.
 924  *
 925  * 2) The buffer variable created by the macro is a pointer to the specified
 926  *    type, and NOT an array of the specified type.  This can be very important
 927  *    if you want the address of the buffer, which you probably do, to pass it
 928  *    to the DMA hardware.  The value of &buffer is different in the two cases.
 929  *    In the macro case it will be the address of the pointer, not the address
 930  *    of the space reserved for the buffer.  However, in the second case it
 931  *    would be the address of the buffer.  So if you are replacing hard coded
 932  *    stack buffers with this macro you need to make sure you remove the & from
 933  *    the locations where you are taking the address of the buffer.
 934  *
 935  * Note that the size parameter is the number of array elements to allocate,
 936  * not the number of bytes.
 937  *
 938  * This macro can not be used outside of function scope, or for the creation
 939  * of a function scoped static buffer.  It can not be used to create a cache
 940  * line aligned global buffer.
