/**

* @file wirish/boards.cpp
|
||||||
|
* @brief init() and board routines.
|
||||||
|
*
|
||||||
|
* 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.
