/*
 * 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
 *
