7df63fcae0 First coarse run to fix coding style in locm3.
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.

99d7b21032 define platform specific constants for all chips
previously, only stm32 chips passed the information about which chip to
build on into the compiler. this information is essential to dispatch,
thus defining LPC13XX, LPC17XX, LPC43XX and LM3S in analogy to
STM32F1..4.

75c2165827 build common .o files everywhere (fixes issue #29)
vector.o, nvic.o, scb.o and assert.o are available on every platform,
but at least some of them differ between the implementations. they
already got built explicityly on some platforms; now adding them to the
common Makefile.include.

a69d83d312 unified vector table initialization
the cortex generic interrupts get moved to lib/cm3/vector.c, the
platorms' individual irq names, initialization and handler prototypes go
to platoform specific irq.h files.

as the vector.c file heavily depends on platoform specific headers, it
can't be built once-and-for-all in lib/cm3/, so there are inclusion
stubs in the various architecture dirs; this might be better solved with
Makefile / include path handling.

one particular file is lib/lpc43xx/vector.c; that platform's
initialization code contains an additional section to copy everything
from flash to ram (which probably performs better there). that code
still resides in the inclusion stub, and gets mashed in using defines.
would need a cleaner implementation together with the Makefile solution.

this commit contains some files of the upcoming efm32 branch, from which
it was cherry-picked.

the .bin files produced from before and after this commit only differ in
lpc43xx, where the startup sequence was subtly modified.

fc4047e4b4 Add assert macros to aid in debugging.
Adds libopencm3/cm3/assert.h header that provides assertion check macros
similar to those provided by the standard C library.

Thanks to Nicolas Schodet for help.

74cd991e7e Use a specific symbol for data source address in flash
That way, data source address does not depend on any other unrelated change in
linker script.

This also fixes cases when .data input section is aligned on 8 bytes.  The new
version does not provide any address for the output section so that it is
aligned to the strictest input section.  The _data_loadaddr symbol will
always take this alignment into account.

2a35377980 Clean up and make linker scripts more uniform
This includes:

 - fix some comments indent,
 - add entry point,
 - align exported symbols,
 - remove unneeded "." assignments.

3441bba1c4 Changed local build target for library and linker files.
- The library files are now being built into the lib subdirectory of the
  source.
- The linker files for each library are being copied into the lib source
  subdirectory.

Motivation: The relative locations of files in the source directory after make
are now the same as after make install now. This makes it easier to
reuse examples with their makefiles outside of the libopencm3
sourcecode directory.
