- * How init() does this is chip-specific. See the chip-specific pieces
- * of Wirish (under e.g. wirish/stm32f1/, wirish/stmf32f2) for
- * details.
+ * 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.
