  20  * GOYA security scheme:
  21  *
  22  * 1. Host is protected by:
  23  *        - Range registers (When MMU is enabled, DMA RR does NOT protect host)
  24  *        - MMU
  25  *
  26  * 2. DRAM is protected by:
  27  *        - Range registers (protect the first 512MB)
  28  *        - MMU (isolation between users)
  29  *
  30  * 3. Configuration is protected by:
  31  *        - Range registers
  32  *        - Protection bits
  33  *
  34  * When MMU is disabled:
  35  *
  36  * QMAN DMA: PQ, CQ, CP, DMA are secured.
  37  * PQ, CB and the data are on the host.
  38  *
  39  * QMAN TPC/MME:
  40  * PQ, CQ and CP are not secured.
  41  * PQ, CB and the data are on the SRAM/DRAM.
  42  *
  43  * Since QMAN DMA is secured, the driver is parsing the DMA CB:
  44  *     - checks DMA pointer
  45  *     - WREG, MSG_PROT are not allowed.
  46  *     - MSG_LONG/SHORT are allowed.
  47  *
  48  * A read/write transaction by the QMAN to a protected area will succeed if
  49  * and only if the QMAN's CP is secured and MSG_PROT is used
  50  *
  51  *
  52  * When MMU is enabled:
  53  *
  54  * QMAN DMA: PQ, CQ and CP are secured.
  55  * MMU is set to bypass on the Secure props register of the QMAN.
  56  * The reasons we don't enable MMU for PQ, CQ and CP are:
  57  *     - PQ entry is in kernel address space and the driver doesn't map it.
  58  *     - CP writes to MSIX register and to kernel address space (completion
  59  *       queue).
  60  *
  61  * DMA is not secured but because CP is secured, the driver still needs to parse
  62  * the CB, but doesn't need to check the DMA addresses.
  63  *
  64  * For QMAN DMA 0, DMA is also secured because only the driver uses this DMA and
  65  * the driver doesn't map memory in MMU.
  66  *
  67  * QMAN TPC/MME: PQ, CQ and CP aren't secured (no change from MMU disabled mode)
  68  *
  69  * DMA RR does NOT protect host because DMA is not secured
