* Bring back and fix up util.c functionality.Marti Bolivar2012-06-263-0/+129
| | | | | | | | | | | | | | | 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 <mbolivar@leaflabs.com>

* Bring back EXTI on F1, with deprecations for gpio.h on F1.Marti Bolivar2012-06-032-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Tested on Maple Mini with examples/mini-exti-test. Changes to Wirish are minor: use the new EXTI types exti_num and exti_cfg (see below) in place of now-deprecated variants in ext_interrupts.cpp. The way I originally did libmaple/exti.h was stupid, and fixing it turned out to be a little disruptive. libmaple/exti.h depends on libmaple/gpio.h (for AFIO), but that's a classic case of exposed implementation detail. So invert the dependency: make gpio.h depend on exti.h. Do this by adding exti_num and exti_cfg to exti.h; these respectively replace afio_exti_num and afio_exti_port. The afio_* variants are now deprecated. (Throw in a typedef and some macros at the bottom of the F1 series/gpio.h for backwards compatibility). Make exti_attach_interrupt() and exti_detach_interrupt() take exti_num/exti_cfg arguments instead of the afio_* variants. Make the EXTI dispatch routines __always_inline to defeat GCC -Os. Many renames throughout libmaple/stm32f1/ to stop using the deprecated names. Also move the previously F1-only gpio_exti_port() function into the public libmaple header. Reimplementing it in terms of rcc_clk_ids lets us deprecate the gpio_dev->exti_port field, which will save space in the future. While we're there, I notice that struct gpio_dev is defined once per series. That's dumb, as it misses the entire point of having device structs: they contain what's portable. So put the F1 version (which has the extra EXTI port field) into libmaple/gpio.h, and add the necessary exti_ports to libmaple/stm32f2/gpio.c. Sigh. We'll get rid of it eventually, at least. Clean up some other mistakes in gpio.h files as well (mostly removing util.h dependency). Sorry for the messy commit. For portability, add a new series-specific exti function, exti_select(). The F1 version in (new) libmaple/stm32f1/exti.c uses AFIO and some new private functionality in libmaple/exti.c and (new) libmaple/exti_private.h to make this convenient. We'll be able to do the SYSCFG equivalent on F2 without any trouble. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
