  764. * Calling the macro as:
  765. *
  766. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  767. *
  768. * Will result in something similar to saying:
  769. *
  770. * uint32_t buffer[1024];
  771. *
  772. * The following differences exist:
  773. *
  774. * 1) The resulting buffer is guaranteed to be aligned to the value of
  775. * ARCH_DMA_MINALIGN.
  776. *
  777. * 2) The buffer variable created by the macro is a pointer to the specified
  778. * type, and NOT an array of the specified type. This can be very important
  779. * if you want the address of the buffer, which you probably do, to pass it
  780. * to the DMA hardware. The value of &buffer is different in the two cases.
  781. * In the macro case it will be the address of the pointer, not the address
  782. * of the space reserved for the buffer. However, in the second case it
  783. * would be the address of the buffer. So if you are replacing hard coded
  784. * stack buffers with this macro you need to make sure you remove the & from
  785. * the locations where you are taking the address of the buffer.
  786. *
  787. * Note that the size parameter is the number of array elements to allocate,
  788. * not the number of bytes.
  789. *
  790. * This macro can not be used outside of function scope, or for the creation
  791. * of a function scoped static buffer. It can not be used to create a cache
  792. * line aligned global buffer.
