  826. * The ALLOC_CACHE_ALIGN_BUFFER macro is used to allocate a buffer on the
  827. * stack that meets the minimum architecture alignment requirements for DMA.
  828. * Such a buffer is useful for DMA operations where flushing and invalidating
  829. * the cache before and after a read and/or write operation is required for
  830. * correct operations.
  831. *
  832. * When called the macro creates an array on the stack that is sized such
  833. * that:
  834. *
  835. * 1) The beginning of the array can be advanced enough to be aligned.
  836. *
  837. * 2) The size of the aligned portion of the array is a multiple of the minimum
  838. * architecture alignment required for DMA.
  839. *
  840. * 3) The aligned portion contains enough space for the original number of
  841. * elements requested.
  842. *
  843. * The macro then creates a pointer to the aligned portion of this array and
  844. * assigns to the pointer the address of the first element in the aligned
  845. * portion of the array.
  846. *
  847. * Calling the macro as:
  848. *
  849. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  850. *
  851. * Will result in something similar to saying:
  852. *
  853. * uint32_t buffer[1024];
  854. *
  855. * The following differences exist:
  856. *
  857. * 1) The resulting buffer is guaranteed to be aligned to the value of
  858. * ARCH_DMA_MINALIGN.
  859. *
  860. * 2) The buffer variable created by the macro is a pointer to the specified
  861. * type, and NOT an array of the specified type. This can be very important
  862. * if you want the address of the buffer, which you probably do, to pass it
  863. * to the DMA hardware. The value of &buffer is different in the two cases.
  864. * In the macro case it will be the address of the pointer, not the address
  865. * of the space reserved for the buffer. However, in the second case it
  866. * would be the address of the buffer. So if you are replacing hard coded
  867. * stack buffers with this macro you need to make sure you remove the & from
  868. * the locations where you are taking the address of the buffer.
  869. *
  870. * Note that the size parameter is the number of array elements to allocate,
  871. * not the number of bytes.
  872. *
  873. * This macro can not be used outside of function scope, or for the creation
  874. * of a function scoped static buffer. It can not be used to create a cache
  875. * line aligned global buffer.
