853 * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the

858 *
859 * When called the macro creates an array on the stack that is sized such

866 *
867 * 3) The aligned portion contains enough space for the original number of
868 * elements requested.

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