  766. * elements requested.
  767. *
  768. * The macro then creates a pointer to the aligned portion of this array and
  769. * assigns to the pointer the address of the first element in the aligned
  770. * portion of the array.
  771. *
  772. * Calling the macro as:
  773. *
  774. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  775. *
  776. * Will result in something similar to saying:
  777. *
  778. * uint32_t buffer[1024];
  779. *
  780. * The following differences exist:
  781. *
  782. * 1) The resulting buffer is guaranteed to be aligned to the value of
  783. * ARCH_DMA_MINALIGN.
  784. *
  785. * 2) The buffer variable created by the macro is a pointer to the specified
  786. * type, and NOT an array of the specified type. This can be very important
  787. * if you want the address of the buffer, which you probably do, to pass it
  788. * to the DMA hardware. The value of &buffer is different in the two cases.
  789. * In the macro case it will be the address of the pointer, not the address
  790. * of the space reserved for the buffer. However, in the second case it
  791. * would be the address of the buffer. So if you are replacing hard coded
  792. * stack buffers with this macro you need to make sure you remove the & from
  793. * the locations where you are taking the address of the buffer.
  794. *
  795. * Note that the size parameter is the number of array elements to allocate,
  796. * not the number of bytes.
  797. *
  798. * This macro can not be used outside of function scope, or for the creation
  799. * of a function scoped static buffer. It can not be used to create a cache
  800. * line aligned global buffer.
