867 * 1) The beginning of the array can be advanced enough to be aligned.
868 *
869 * 2) The size of the aligned portion of the array is a multiple of the minimum
870 * architecture alignment required for DMA.
871 *
872 * 3) The aligned portion contains enough space for the original number of
873 * elements requested.
874 *
875 * The macro then creates a pointer to the aligned portion of this array and
876 * assigns to the pointer the address of the first element in the aligned
877 * portion of the array.
878 *
879 * Calling the macro as:
880 *
881 * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
882 *
883 * Will result in something similar to saying:
884 *
885 * uint32_t buffer[1024];
886 *
887 * The following differences exist:
888 *
889 * 1) The resulting buffer is guaranteed to be aligned to the value of
890 * ARCH_DMA_MINALIGN.
891 *
892 * 2) The buffer variable created by the macro is a pointer to the specified
893 * type, and NOT an array of the specified type. This can be very important
894 * if you want the address of the buffer, which you probably do, to pass it
895 * to the DMA hardware. The value of &buffer is different in the two cases.
896 * In the macro case it will be the address of the pointer, not the address
897 * of the space reserved for the buffer. However, in the second case it
898 * would be the address of the buffer. So if you are replacing hard coded
899 * stack buffers with this macro you need to make sure you remove the & from
900 * the locations where you are taking the address of the buffer.
901 *
902 * Note that the size parameter is the number of array elements to allocate,
903 * not the number of bytes.
904 *
905 * This macro can not be used outside of function scope, or for the creation
906 * of a function scoped static buffer. It can not be used to create a cache
907 * line aligned global buffer.
