The EREF defines some architecture categories not defined 19*4882a593Smuzhiyun by the Power ISA. For these EREF-specific categories, the existence of 20*4882a593Smuzhiyun a property named fsl,eref-[CAT], where [CAT] is the abbreviated category 21*4882a593Smuzhiyun name with all uppercase letters converted to lowercase, indicates that 22*4882a593Smuzhiyun the category is supported by the implementation. 23*4882a593Smuzhiyun 24*4882a593Smuzhiyun - fsl,portid-mapping 25*4882a593Smuzhiyun Usage: optional 26*4882a593Smuzhiyun Value type: <u32> 27*4882a593Smuzhiyun Definition: The Coherency Subdomain ID Port Mapping Registers and 28*4882a593Smuzhiyun Snoop ID Port Mapping registers, which are part of the CoreNet 29*4882a593Smuzhiyun Coherency fabric (CCF), provide a CoreNet Coherency Subdomain 30*4882a593Smuzhiyun ID/CoreNet Snoop ID to cpu mapping functions. Certain bits from 31*4882a593Smuzhiyun these registers should be set if the coresponding CPU should be 32*4882a593Smuzhiyun snooped. This property defines a bitmask which selects the bit 33*4882a593Smuzhiyun that should be set if this cpu should be snooped. 34
