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