*
* This file is mostly interesting for the init() function, which
* configures Flash, the core clocks, and a variety of other available
* peripherals on the board so the rest of Wirish doesn't have to turn
* things on before using them.
*
* Prior to returning, init() calls boardInit(), which allows boards
* to perform any initialization they need to. This file includes a
* weak no-op definition of boardInit(), so boards that don't need any
* special initialization don't have to define their own.
*
* How init() works is chip-specific. See the boards_setup.cpp files
* under e.g. wirish/stm32f1/, wirish/stmf32f2 for the details, but be
* advised: their contents are unstable, and can/will change without
* notice.
