Thank you for your answer. MPC8xx (I use 860) is different from the i2c point
of view; it is more like the serial driver (it uses buffer descriptors,
parameter area, etc.). I was thinking to create this driver in the
hal/powerpc/quick folder, similar to quick_smc1, but this i2c might be more
particular, so, as you suggested, I will add it in my board specific files.
Thank you again,
Radu
