  761. * elements requested.
  762. *
  763. * The macro then creates a pointer to the aligned portion of this array and
  764. * assigns to the pointer the address of the first element in the aligned
  765. * portion of the array.
  766. *
  767. * Calling the macro as:
  768. *
  769. * ALLOC_CACHE_ALIGN_BUFFER(uint32_t, buffer, 1024);
  770. *
  771. * Will result in something similar to saying:
  772. *
  773. * uint32_t buffer[1024];
  774. *
  775. * The following differences exist:
  776. *
  777. * 1) The resulting buffer is guaranteed to be aligned to the value of
  778. * ARCH_DMA_MINALIGN.
  779. *
  780. * 2) The buffer variable created by the macro is a pointer to the specified
  781. * type, and NOT an array of the specified type. This can be very important
  782. * if you want the address of the buffer, which you probably do, to pass it
  783. * to the DMA hardware. The value of &buffer is different in the two cases.
  784. * In the macro case it will be the address of the pointer, not the address
  785. * of the space reserved for the buffer. However, in the second case it
  786. * would be the address of the buffer. So if you are replacing hard coded
  787. * stack buffers with this macro you need to make sure you remove the & from
  788. * the locations where you are taking the address of the buffer.
  789. *
  790. * Note that the size parameter is the number of array elements to allocate,
  791. * not the number of bytes.
  792. *
  793. * This macro can not be used outside of function scope, or for the creation
  794. * of a function scoped static buffer. It can not be used to create a cache
  795. * line aligned global buffer.
