librambutan/wirish/stm32f2, branch legacy

Bring back and fix up util.c functionality.

2012-06-26T22:03:40Z

Rip out the existing nonportable pieces, and shove them under wirish/stm32f1, using weak symbols so users who only want libmaple proper don't end up with build errors. Add stubbed-out (and only partially functional) definitions for F2 targets under wirish/stm32f2. The behavior on F103 targets is the same as it was before (though the assertion framework has always been broken and badly needs replacement, that awaits another commit). We additionally now skip re-enabling USB on F1 targets without USB, to make things work on value line MCUs. Signed-off-by: Marti Bolivar

STM32F2: Add timer_get_af().

Pull some code out of the F2 pinMode() into a utility function. This feels generally useful enough to be exposed to the users (it will, for example, make it easier to implement input capture in a clean way). Signed-off-by: Marti Bolivar

STM32F2: fix pinMode() for PWM, PWM_OPEN_DRAIN.

Make it so the call to gpio_set_modef() actually happens. Signed-off-by: Marti Bolivar

Bring timer initialization back to init().

Turns out the F1 code was pretty portable after all, so take it from the F1 boards_setup.cpp and stick it back into boards.cpp. The only change needed was to add a call to the newly-minted timer_has_cc_channel() (and this is necessary on F103 XL-density, anyway). Also assert LeafLabs copyright in boards.cpp. We really need to do this throughout the library; it's basically been rewritten since Perry. Signed-off-by: Marti Bolivar
