Notice I said system, not architecture. The way the device registers are fixed is what I mean by native endianness. If the purpose of adding this property now is to support GUTS on the ARM SoCs, then I'd argue using this property is probably wrong. If the PPC systems are designed with BE device registers and ARM systems with LE, then this property is not needed. > I think the property here is fine. Unless you have studied the FSL ARM based SoCs, then there is not enough information here to tell.
