8 title: Intel HPS Copy Engine
11   - Matthew Gerlach <matthew.gerlach@linux.intel.com>
14   The Intel Hard Processor System (HPS) Copy Engine is an IP block used to copy
15   a bootable image from host memory to HPS DDR.  Additionally, there is a
16   register the HPS can use to indicate the state of booting the copied image as
17   well as a keep-a-live indication to the host.
