c72f3d588a Surround all macro parameters with ()
All the macro arguments that are user supplied, or potentially, wrap properly
in () as good practice.

Probably missed one or two, and a lot of them are possibly unnecessary, but
it's straightforward to just do it always.

Fixes github issue #321

7681597e42 Use type suffix to avoid warnings
When compiling with all warnings enabled, some defines can lead to
warning due to missing unsigned type suffix:

warning: integer overflow in expression [-Woverflow]

This fix should not affected behavior at all, since calculation with
such overflows lead to the same actual address when writing to that
location. However, it makes the warning disappear and also defines
the right data type for a memory location.

5c14780403 [build] Remove PyYAML dependency
This converts all the YAML files to JSON files, as json parsing is built
into python instead of being a separate library requiring installation.

YAML is a superset of JSON, but putting comments in is not quite as obvious
as it is in yaml.

The following glue was used to convert yaml to json:
python -c 'import sys, yaml, json; json.dump(yaml.load(sys.stdin), sys.stdout, indent=4)' < $1 > $2

Clearly I haven't tested this on every single platform, and this
doesn't address the large blobs of yaml in the lpc4300 scripts directory,
only the cortex NVIC generation process.

I've tested a few IRQ driven example apps, and I've checked the generated
output of some known cases like the LM3s that has explicit gaps, and they are
all generated correctly.

8da7fbd71e Changed to use accessors instead of casting to volatile pointers.
In places where we were defining memory mapped peripheral buffers we
were using directly a cast to "volatile int_type *". For consistency we
should use dereferenced accessor like: &MMIO32(address)

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.

326c945b55 lm4f: Add lm4f support files copied from lm3s
Create lm4f code infrastructure from the lm3s infrastructure.

As far as the interrupt table is concerned, don't create an irq.yaml. Just
include the LM3S nvic.h. The LM3S vector table seems to be compatible with the
LM4F

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.

ff83a1ae1c Setup to document entire project using doxygen.
New doc directory with config files and generated html, LaTeX/pdf.
Makefile provided for autogeneration and explanatory README.

The project structure is hostile to doxygen, which can't cope with functions
of the same name. Doxygen is run for each family separately, and separately
for LaTeX generation. Customized layout files sort of "integrate" HTML, and
separate pdfs are generated for each family. Not ideal but seems the best
solution until doxygen changes, if at all.
