Very new gcc versions add a warning on switch cases that fall through.
While there's an option that accepts any comment as explaining it, it's
easier in our case to just use one of the "blessed" comments. We can't
use the [[]] attributes for standards code, and the gcc specific
attributes are worse than the comments. This has no functional change
whatsoever.
Clearly staging branch testers weren't testing.
Also, clearly the separation of RST_ bits and RCC_ bits is a complicated
annoyance.
Fixes: d9615a2eb728 update to modern include apis
Added --terse and --mailback options to the make stylecheck target. It
also does continue even if it enounters a possible error.
We decided on two exceptions from the linux kernel coding standard:
- Empty wait while loops may end with ; on the same line.
- All blocks after while, if, for have to be in brackets even if they
only contain one statement. Otherwise it is easy to introduce an
error.
Checkpatch needs to be adapted to reflect those changes.
All #includes now explicitly use the "<libopencm3/stm32/rcc.h>" format.
If you want to get rid of the "libopencm3" prefix in your local project you
can add a respective -I entry in your Makefile (not recommended though).
All .ld files and .a libs are installed in $(TOOLCHAIN_DIR)/lib
directly (as before), but are now renamed to avoid potential
conflicts now or in the future. Examples:
libopencm3_lpc13xx.a
libopencm3_lpc13xx.ld
libopencm3_stm32.a
libopencm3_stm32.ld
