/*
 * Gaudi security scheme:
 *
 * 1. Host is protected by:
 *        - Range registers
 *        - MMU
 *
 * 2. DDR is protected by:
 *        - Range registers (protect the first 512MB)
 *
 * 3. Configuration is protected by:
 *        - Range registers
 *        - Protection bits
 *
 * MMU is always enabled.
 *
 * QMAN DMA channels 0,1 (PCI DMAN):
 *     - DMA is not secured.
 *     - PQ and CQ are secured.
 *     - CP is secured: The driver needs to parse CB but WREG should be allowed
 *                      because of TDMA (tensor DMA). Hence, WREG is always not
 *                      secured.
 *
 * When the driver needs to use DMA it will check that Gaudi is idle, set DMA
 * channel 0 to be secured, execute the DMA and change it back to not secured.
 * Currently, the driver doesn't use the DMA while there are compute jobs
 * running.
 *
 * The current use cases for the driver to use the DMA are:
 *     - Clear SRAM on context switch (happens on context switch when device is
 *       idle)
 *     - MMU page tables area clear (happens on init)
 *
 * QMAN DMA 2-7, TPC, MME, NIC:
 * PQ is secured and is located on the Host (HBM CON TPC3 bug)
 * CQ, CP and the engine are not secured
 *
