+DDR Configuration
+-----------------
+
+The K3 DDRSS driver (drivers/ram/k3-ddrss/k3-ddrss.c) configures the DDR during
+the R5 SPL stage. The driver utilizes an auto-generated configuration file
+containing necessary settings for the DDR. It configures the frequency, timing
+parameters, training algorithms etc. for DDR initialization. The configuration
+DTSI can be generated using the `Sysconfig tool <https://dev.ti.com/sysconfig>`_
+and selecting the software product as "DDR Configuration for \*" as well as the
+required device.
