- * The Intel Mount Evans SoC's Integrated Management Complex uses the

- * This driver doesn't use DMA for memory operations when a chip select
- * override is not provided due to the native chip select timing behavior.
- * As a result no DMA configuration is done for the controller and this
- * configuration is not tested.
+ * DMA-based mem ops are not configured for this device and are not tested.
