  864. * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
  865. * stack that meets the minimum architecture alignment requirements for DMA.
  866. * Such a buffer is useful for DMA operations where flushing and invalidating
  867. * the cache before and after a read and/or write operation is required for
  868. * correct operations.
  869. *
  870. * When called the macro creates an array on the stack that is sized such
  871. * that:
  872. *
  873. * 1) The beginning of the array can be advanced enough to be aligned.
  874. *
  875. * 2) The size of the aligned portion of the array is a multiple of the minimum
  876. * architecture alignment required for DMA.
  877. *
  878. * 3) The aligned portion contains enough space for the original number of
  879. * elements requested.
  880. *
  881. * The macro then creates a pointer to the aligned portion of this array and
  882. * assigns to the pointer the address of the first element in the aligned
  883. * portion of the array.
  884. *
  885. * Calling the macro as:
  886. *
  887. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  888. *
  889. * Will result in something similar to saying:
  890. *
  891. * uint32_t buffer[1024];
  892. *
  893. * The following differences exist:
  894. *
  895. * 1) The resulting buffer is guaranteed to be aligned to the value of
  896. * ARCH_DMA_MINALIGN.
  897. *
  898. * 2) The buffer variable created by the macro is a pointer to the specified
  899. * type, and NOT an array of the specified type. This can be very important
  900. * if you want the address of the buffer, which you probably do, to pass it
  901. * to the DMA hardware. The value of &buffer is different in the two cases.
  902. * In the macro case it will be the address of the pointer, not the address
  903. * of the space reserved for the buffer. However, in the second case it
  904. * would be the address of the buffer. So if you are replacing hard coded
  905. * stack buffers with this macro you need to make sure you remove the & from
  906. * the locations where you are taking the address of the buffer.
  907. *
  908. * Note that the size parameter is the number of array elements to allocate,
  909. * not the number of bytes.
  910. *
  911. * This macro can not be used outside of function scope, or for the creation
  912. * of a function scoped static buffer. It can not be used to create a cache
  913. * line aligned global buffer.
