This was inspired by an Arch Linux provided ARM GCC 5.3.0 bug:
It gave an
"internal compiler error: in expand_expr_addr_expr_1, at expr.c:7736"
with the array version of the desig_get_unique_id.
While I was at it, fixed:
- a potential alignment issue with casting uint8_t* buf to uint32_t*
- a funny static in the string definition that does nothing (given const)
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.
STM32L1 has a different set of offsets, not just a different base
address, so we can't have common registers definitions. Also, out of
F0,F1,F2,F3,F4,L1, only the F1 has the odd note about 2x16bit registers
and 2x32bit registers with one 16bit register marked as "This field
value is also reserved for a future feature." Therefore, replace the
awkward reading out as multiple words and just copy them in.
F0,F2,F3,F4 were missing definitions altogether.
This does _not_ attempt to address the problem of the mismatched base
addresses for Medium+ and High Density L1 parts.
