   15   The ZynqMP DDR ECC controller has an optional ECC support in 64-bit and
   16   32-bit bus width configurations.

   18   The Zynq DDR ECC controller has an optional ECC support in half-bus width
   19   (16-bit) configuration.
   20 
   21   These both ECC controllers correct single bit ECC errors and detect double bit
   22   ECC errors.
