d3e41e7b58 cpu/sam21: removed superfluous gpio_init_sercom 
This function was a duplication of the existing gpio_init_mux,
where the exiting function is the more general one, as the mux
inititalization is not only valid for the sercom module...

bac5cda1e3 periph/i2c: convert char to uint8_t where applicapable 
In general, data transferred through I2C are bytes and thus should have
type uint8_t, not char.

Also convert uint8_t ptrs to void ptrs

076d5bda11 boards: add support for SODAQ Autonomo 
The following features were tested (briefly):
* UART (the first)
* I2C using a BMP180 on a SODAQ TPH board
* SPI0, connected to the on-board serial data flash (only DevID was read
using the periph_spi test program)
* xtimer is working (it's the same code as in samr21)

boards/sodaq-autonomo: Disable the "big" unittests because it does not fit

3123b501b5 cpu/sam21_common: add samd21 include files from ASF CMSIS 
This adds support for all samd21 variants. Notice that the previous samd21
was moved to cpu/samr21

To use this cpu variant you must set at least the following in your boards
Makefile.include:
    export CPU = samd21
    export CPU_MODEL = samd21j18a   # Not sure if this is used
    CFLAGS += -D__SAMD21J18A__  # or whatever variant you have

The samd21 include files were copied from ASF 3.30

2a4655b6f8 cpu/samd21: rewrite i2c_init_master to make use of gpio_init_sercom 
The former i2c_init_master was too complicated. It was trying to set IN/OUT
mode of the pins, but all that is needed is to set the proper MUX.

Also the configuration for the boards was incomplete (no MUX, no pad
setting).

It was tested on a SODAQ Autonomo, but not on a samr21-xpro

e0365e0bf9 atmega: use software interrupt for context swap 
Fixes #5745
For AVR based boards, three defines must be defined AVR_CONTEXT_SWAP_INIT,
AVR_CONTEXT_SWAP_INTERRUPT_VECT, and AVR_CONTEXT_SWAP_TRIGGER.
These defines are used to trigger a software interrupt used for context
switching.

When AVR_CONTEXT_SWAP_INTERRUPT_VECT is handled, the scheduler is run
and a context swap will happen if necessary, with the resulting thread
starting following the reti instruction. This results in threads running
at normal priority instead of at interrupt priority.

Atmega devices do provide a pure software interrupt. The method used
here for waspmote-pro and arduino-mega2560 is to use pin change
interrupts, set the pin to act as an output, and toggle the value to
simulate a software interrupt. The main limitation here is that a
physical pin is now occupied and must be defined for each board
supported by RIOT. On the plus side, it provides an easy method for
detecting context swaps with an oscilloscope.
