/*
* 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, KMD is parsing the DMA CB:
* - KMD 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 KMD 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, KMD 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 KMD uses this DMA and KMD
* 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
