22  * GOYA security scheme:
23  *
24  * 1. Host is protected by:
25  *        - Range registers (When MMU is enabled, DMA RR does NOT protect host)
26  *        - MMU
27  *
28  * 2. DRAM is protected by:
29  *        - Range registers (protect the first 512MB)
30  *        - MMU (isolation between users)
31  *
32  * 3. Configuration is protected by:
33  *        - Range registers
34  *        - Protection bits
35  *
36  * When MMU is disabled:
37  *
38  * QMAN DMA: PQ, CQ, CP, DMA are secured.
39  * PQ, CB and the data are on the host.
40  *
41  * QMAN TPC/MME:
42  * PQ, CQ and CP are not secured.
43  * PQ, CB and the data are on the SRAM/DRAM.
44  *
45  * Since QMAN DMA is secured, the driver is parsing the DMA CB:
46  *     - checks DMA pointer
47  *     - WREG, MSG_PROT are not allowed.
48  *     - MSG_LONG/SHORT are allowed.
49  *
50  * A read/write transaction by the QMAN to a protected area will succeed if
51  * and only if the QMAN's CP is secured and MSG_PROT is used
52  *
53  *
54  * When MMU is enabled:
55  *
56  * QMAN DMA: PQ, CQ and CP are secured.
57  * MMU is set to bypass on the Secure props register of the QMAN.
58  * The reasons we don't enable MMU for PQ, CQ and CP are:
59  *     - PQ entry is in kernel address space and the driver doesn't map it.
60  *     - CP writes to MSIX register and to kernel address space (completion
61  *       queue).
62  *
63  * DMA is not secured but because CP is secured, the driver still needs to parse
64  * the CB, but doesn't need to check the DMA addresses.
65  *
66  * For QMAN DMA 0, DMA is also secured because only the driver uses this DMA and
67  * the driver doesn't map memory in MMU.
68  *
69  * QMAN TPC/MME: PQ, CQ and CP aren't secured (no change from MMU disabled mode)
70  *
71  * DMA RR does NOT protect host because DMA is not secured
