Aruba Ap315 SPI help

I am trying to find out where is the hardware info(serial number, mac address etc like calibration-data is per-device and should not be interchanged between different boards) at the spi (MX25U3235F ) of the Aruba 315. There is another topic about Aruba 303 someone says that there is a appsbl partition but I cannot findout where is the appsbl partition at the MX25U3235F chip. Can you help me about it?

Here is the SPI(MX25U3235F ) binwalk output.
