+ * GOYA security scheme:
+ *
+ * 1. Host is protected by:
+ * - Range registers (When MMU is enabled, DMA RR does NOT protect host)
+ * - MMU
+ *
+ * 2. DRAM is protected by:
+ * - Range registers (protect the first 512MB)
+ * - MMU (isolation between users)
+ *
+ * 3. Configuration is protected by:
+ * - Range registers
+ * - Protection bits
+ *
+ * When MMU is disabled:
+ *
+ * QMAN DMA: PQ, CQ, CP, DMA are secured.
+ * PQ, CB and the data are on the host.
+ *
+ * QMAN TPC/MME:
+ * PQ, CQ and CP are not secured.
+ * PQ, CB and the data are on the SRAM/DRAM.
+ *
+ * Since QMAN DMA is secured, the driver is parsing the DMA CB:
+ * - checks DMA pointer
+ * - WREG, MSG_PROT are not allowed.
+ * - MSG_LONG/SHORT are allowed.
+ *
+ * A read/write transaction by the QMAN to a protected area will succeed if
+ * and only if the QMAN's CP is secured and MSG_PROT is used
+ *
+ *
+ * When MMU is enabled:
+ *
+ * QMAN DMA: PQ, CQ and CP are secured.
+ * MMU is set to bypass on the Secure props register of the QMAN.
+ * The reasons we don't enable MMU for PQ, CQ and CP are:
+ * - PQ entry is in kernel address space and the driver doesn't map it.
+ * - CP writes to MSIX register and to kernel address space (completion
+ * queue).
+ *
+ * DMA is not secured but because CP is secured, the driver still needs to parse
+ * the CB, but doesn't need to check the DMA addresses.
+ *
+ * For QMAN DMA 0, DMA is also secured because only the driver uses this DMA and
+ * the driver doesn't map memory in MMU.
+ *
+ * QMAN TPC/MME: PQ, CQ and CP aren't secured (no change from MMU disabled mode)
+ *
+ * DMA RR does NOT protect host because DMA is not secured
