  858. * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
  859. * stack that meets the minimum architecture alignment requirements for DMA.
  860. * Such a buffer is useful for DMA operations where flushing and invalidating
  861. * the cache before and after a read and/or write operation is required for
  862. * correct operations.
  863. *
  864. * When called the macro creates an array on the stack that is sized such
  865. * that:
  866. *
  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.
