cpu/stm32_common: Use a different module name to prevent linker races in Travis 2016-02-12 00:49:30 +01:00			`MODULE = stm32_common_periph`

cpu/stm32_common: Do not use USEMODULE to select i2c implem `cpu/stm32_common/Makefile.dep` was never included by the global `Makefile.dep`, so declaring this `USEMODULE +=` here was never shown to the build system and never exported as `MODULE_PERIPH_I2C_X` variables. In fact, `USEMODULE` was only used to trigger the `periph.mk`/`SUBMODULES` mechanism to add matching source files names to `SRC` and so select the implementation for each CPU type. It is replaced by just explicitly selecting the right source file. 2018-10-11 15:13:15 +02:00			# Select the specific implementation for `periph_i2c`

cpu/stm32_common: split common i2c periph in 2 - i2c_1 is built for f0, f3, f7, l0 and l4 - i2c_2 is built for f4 2018-05-31 15:56:53 +02:00
cpu/stm32_common: remove inadapted periph_flash_common The `periph_flash_common` feature was only defined here to trigger inclusion of a source file with common functions. It even only defines private symbols `_lock` and `_unlock` so no reason to expose it to the build system. And in practice, all stm cpus providing `periph_flashpage` or `periph_eeprom` were required to provide `periph_flash_common` to allow including it. The previous implementation was only parsing in the modules were in `FEATURES_REQUIRED` wich did not take cases of `FEATURES_OPTIONAL` into account. And also, in the same time, as the dependencies was declared in `Makefile.include` it was processed before `Makefile.dep` so never handled cases where a module could depend on `periph_flashpage` or `periph_eeprom` feature. It is replaced by selecting the common source file when module using it are included. The now useless feature `periph_flash_common` is removed from `FEATURES_PROVIDED`. 2018-10-11 15:20:44 +02:00			`# flashpage and eeprom periph implementations share flash lock/unlock functions`
