description: |
The ZynqMP DDR ECC controller has an optional ECC support in 64-bit and
32-bit bus width configurations.
The Zynq DDR ECC controller has an optional ECC support in half-bus width
(16-bit) configuration.
These both ECC controllers correct single bit ECC errors and detect double bit
ECC errors.
