Radomir Dopieralski e0733d153e SAMD: configurable brownout, separate the variables 2020-07-09 12:17:07 +02:00
Radomir Dopieralski 83a27edd20 SAMD: make the brownout detection level configurable per board 
Not all boards have external flash or other components that make them
require 2.7V -- sometimes we can get considerably longer battery life
by decreasing this requirement.

In particular, pewpew10 and pewpew_m4 are powered directly from
battery, with no LDO, and should work fine down to 1.6V.
