Ivan Grokhotkov	3b583c150f	bootloader: disconnect VRTC from SAR input in bootloader_random_disable ... Bootloader enables SAR ADC in test mode to get some entropy for the RNG. The bits which control the ADC test mux were not disabled, which caused extra ~24uA current to be drawn from VRTC, increasing deep sleep current consumption. This change disables relevant test mode bits in bootloader_random_disable.	2017-02-21 17:07:15 +08:00
