Hi Viktor,

first a disclaimer:

It is a lot of time that I don't work with msp430 silicon, so my knowledge
it is not up to date,
so please take this a a starting point: I think a RIOT msp430 maintainer
could make a more clean and polite job than me,
and I think it would be a GREAT thing.

Now some info and a recipe to try get a working RIOT port to "the new"

I have arranged a build for chronos board with the fork:

https://github.com/attdona/RIOT (some minor patches about removing
duplicated types definition and the new msp430 gcc ISR syntax)

and with the following compiler version (not mandatory, just for

msp430-elf-gcc -v
Using built-in specs.
Target: msp430-elf
Configured with: /home/attilio/MIOT/gcc_repo/gcc/configure
--prefix=/usr/local/gcc-msp430-elf-dev-20141215 --target=msp430-elf
--with-newlib --enable-languages=c
Thread model: single
gcc version 5.0.0 20141105 (experimental) (GCC)

The ugly part it is that I needed to patch the compiler !!!

You will find the instructions into cpu/msp430-common/gcc-patch/README.md

I've just verified that the platform build successfully but I have not
tested the fw.

Let me know if it works for you.
