+ * Gaudi security scheme:
+ *
+ * 1. Host is protected by:
+ * - Range registers
+ * - MMU
+ *
+ * 2. DDR is protected by:
+ * - Range registers (protect the first 512MB)
+ *
+ * 3. Configuration is protected by:
+ * - Range registers
+ * - Protection bits
+ *
+ * MMU is always enabled.
+ *
+ * QMAN DMA channels 0,1 (PCI DMAN):
+ * - DMA is not secured.
+ * - PQ and CQ are secured.
+ * - CP is secured: The driver needs to parse CB but WREG should be allowed
+ * because of TDMA (tensor DMA). Hence, WREG is always not
+ * secured.
+ *
+ * When the driver needs to use DMA it will check that Gaudi is idle, set DMA
+ * channel 0 to be secured, execute the DMA and change it back to not secured.
+ * Currently, the driver doesn't use the DMA while there are compute jobs
+ * running.
+ *
+ * The current use cases for the driver to use the DMA are:
+ * - Clear SRAM on context switch (happens on context switch when device is
+ * idle)
+ * - MMU page tables area clear (happens on init)
+ *
+ * QMAN DMA 2-7, TPC, MME, NIC:
+ * PQ is secured and is located on the Host (HBM CON TPC3 bug)
+ * CQ, CP and the engine are not secured
+ *
