I don't think this means it's CPU dependend.
Assume we need 5 more init routines for the I2C code. It makes sense
to put all this in the i2c_init() code. It makes no sense to me to
put all this in the board.c file - we have only one I2C sub-system,
so there should be only one init function call for it.
