This CANWBS defines the coherency of memory accesses to be not marked IOWB cacheable/shareable. Its value further implies the coherency impact from a pair of mismatched memory attributes (e.g. in a nested translation case): 0x0: Use of mismatched memory attributes for accesses made by this device may lead to a loss of coherency. 0x1: Coherency of accesses made by this device to locations in Conventional memory are ensured as follows, even if the memory attributes for the accesses presented by the device or provided by the SMMU are different from Inner and Outer Write-back cacheable, Shareable.
