Move the last few register defines back to their relevant headers, add
doxygen and groups. While these registers _were_ "common" they were the
_only_ common things, so it's simpler for future work (merging f7 with
f2/4) to move them back separately.
F3's flash interface is actually quite different, don't try and force
sharing code that isn't really related. The "PGERR" is a very different
bit than the parallelism error that f2/4/7 have.
All the "f" type flash parts have an EOP flag, even if it's in different
bit positions. Add a header for this common functionality, and move
it's implementation to the existing common file.
Turns out, there's lots of common code for flash. Pull up prefetch
on/off to start with, as there's only a single bit name different.
Pull up the definitions of common API functions too, starting with
flash_set_ws. Even if the implementations are different, things that
meant to be the same, should be defined centrally.
to remove variations, redundancies, add missing, fix errors. All c files
refer only to the dispatch style headers in /include/stm32. Those headers
#include memorymap.h and cm3/common.h. All references to
these are removed from the family specific headers. Ethernet untouched as
it appears incomplete.
Added dummy spi.c for F0/F3. Fix some doxygen anomalies.
- Makefiles of other stm32s updated accordingly.
- f3/rcc.c updated to some definition changes.
- f3/flash.c removed in order to use flash_common_f234.c to comply with new organization.
