build system: Refactor component.mk to not need component_common.mk New makefile component_wrapper.mk allows some variables to be set before component.mk is evaluated. This properly fixes problems with sdkconfig being hard to access in all phases of the build. Including component_common.mk is no longer necessary and will print a deprecation warning for components which use it. 2016-11-09 21:20:55 -05:00			`# Main bootloader Makefile.`

disable PHY and RF when stop WiFi and disable BT 1. Add disable PHY and RF when WiFi and BT are both disabled(including call sniffer disable API). 2. Do not init PHY and RF when cpu start. Init PHY and RF when call Wifi or BT start APIs(including sniffer enable API). 3. Add a temporary lib: librtc_clk.a and will delete it when CPU frequency switching function is done. 4. Add an function to get OS tick rate. 5. Do not put the whole pp.a in iram0, only put lmac.o, ieee80211_misc.o, ets_time.o and wdev.o in iram0. 2017-02-16 06:05:07 -05:00			`COMPONENT_ADD_LDFLAGS += -L $(IDF_PATH)/components/esp32/lib/ -lrtc_clk -lrtc`
