A new blue pill variant with only 32 KiB of flash (secretly coming with
64 KiB flash) instead of the use 64 KiB flash (secretly coming with 128 KiB)
is not compatible with `make flash`. This commit changes the OpenOCD config
so that both variants can be flashed.
DEBUGGER/DEBUGGER_FLAGS/DEBUGSERVER/DEBUGSERVER_FLAGS are evaluated by the
main Makefile.include or by file included by it.
Their value does not need to be exported.
Testing
-------
`git diff --word-diff` only reports `export` being removed.
`git show --stat` reports `55 insertions(+), 55 deletions(-)`
Which is the same amount as lines that where matching
`export[[:blank::]]\+VARIABLE`.
RESET and RESET_FLAGS are evaluated by the main Makefile.include or by file
included by it. Their value does not need to be exported.
This will also prevent evaluating 'PORT' for RESET_FLAGS when not needed.

This commit fixes configuration problems when trying to use i2c pins that need to be remapped.
All B8 and B9 pins for STM32F1 need to be remapped, so a check is done if the remappable pins are selected.
In commit e90f2b439e the I2C config has been
adapted to the new I2C API. However, the pins of I2C_DEV(0) have been changed
from PB6 and PB7 to PB8 and PB9. While PB8 and PB9 also can be used for I2C1
by remapping I2C1, this is not done. As a result, I2C1 was unusable. This
commit restores the default I2C1 pins for I2C_DEV(0), resulting in I2C_DEV(0)
becoming usable again.
The STM32F103C8 secretly comes with 128KiB flash instead of 64KiB. Still, only
64KiB of it are tested and guaranteed to work. However, most of the times the
whole 128KiB flash works just fine. In the BluePill documentation this fact is
already documented and by using
$ make BOARD=bluepill CPU_MODEL=stm32f103cb
the whole 128 KiB can be used by RIOT. When using this hack routinely, it easier
to use environment variables instead. But allowing to overwrite CPU_MODEL via
environment variables seems to be a bad thing, as it is easy to forget to clear
that environment variable when changing the BOARD variable.
This commit introduces the new STM32F103C8_FLASH_HACK variable, which unlocks
the 128KiB FLASH when set to "1". The BluePill documentation has been updated
accordingly.
The file always exist so no need to do '-include'.
Replaced using:
sed -i 's|-\(include $(RIOTCPU)/.*/Makefile.features\)|\1|' \
$(git grep -l '$(RIOTCPU)/.*/Makefile.features' boards)
When flashing multiple times the flasher gets stuck.
Default configuration is used that fixes running mulitple tests.
-c 'reset halt' is needed to support debug after config is changed.
