Dear Russell,

The NUC932 is not same to NUC900 series SoCs, which contains sensor interface supports, H/W JPEG image codec,TV-Out and there are not different register addressing between them,but there are the same IPs in VIC, uart, timer.so I add the nuc932 platform to my nuc900 and modify some interfaces of nuc900 to apply to nuc932, for avoiding wasteful duplication of codes.
