  842. * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
  843. * stack that meets the minimum architecture alignment requirements for DMA.
  844. * Such a buffer is useful for DMA operations where flushing and invalidating
  845. * the cache before and after a read and/or write operation is required for
  846. * correct operations.
  847. *
  848. * When called the macro creates an array on the stack that is sized such
  849. * that:
  850. *
  851. * 1) The beginning of the array can be advanced enough to be aligned.
  852. *
  853. * 2) The size of the aligned portion of the array is a multiple of the minimum
  854. * architecture alignment required for DMA.
  855. *
  856. * 3) The aligned portion contains enough space for the original number of
  857. * elements requested.
  858. *
  859. * The macro then creates a pointer to the aligned portion of this array and
  860. * assigns to the pointer the address of the first element in the aligned
  861. * portion of the array.
  862. *
  863. * Calling the macro as:
  864. *
  865. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  866. *
  867. * Will result in something similar to saying:
  868. *
  869. * uint32_t buffer[1024];
  870. *
  871. * The following differences exist:
  872. *
  873. * 1) The resulting buffer is guaranteed to be aligned to the value of
  874. * ARCH_DMA_MINALIGN.
  875. *
  876. * 2) The buffer variable created by the macro is a pointer to the specified
  877. * type, and NOT an array of the specified type. This can be very important
  878. * if you want the address of the buffer, which you probably do, to pass it
  879. * to the DMA hardware. The value of &buffer is different in the two cases.
  880. * In the macro case it will be the address of the pointer, not the address
  881. * of the space reserved for the buffer. However, in the second case it
  882. * would be the address of the buffer. So if you are replacing hard coded
  883. * stack buffers with this macro you need to make sure you remove the & from
  884. * the locations where you are taking the address of the buffer.
  885. *
  886. * Note that the size parameter is the number of array elements to allocate,
  887. * not the number of bytes.
  888. *
  889. * This macro can not be used outside of function scope, or for the creation
  890. * of a function scoped static buffer. It can not be used to create a cache
  891. * line aligned global buffer.
