HAL Driver for Zigbee,Thread,ZWave and NFC

From matrix github account i can see that Zigbee and ZWave drivers are implemented on MALOS level. Also i dont find any info about NFC ( there is some unstable git project but its status unclear ). Thread network is supported by EMS358X chip , however i dont find any documentation for it.

Please help me with following questions

  1. Where can i find SPI spec for Zigbee,ZWave,Thread and NFC
  2. Could Thread and Zigbee work at same time on same chip?
