hw/misc/iotkit-secctl: Add remaining simple registers
Add remaining easy registers to iotkit-secctl: * NSCCFG just routes its two bits out to external GPIO lines * BRGINSTAT/BRGINTCLR/BRGINTEN can be dummies, because QEMU's bus fabric can never report errors Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 20180220180325.29818-18-peter.maydell@linaro.org
