Hi Uwe

I just applied your patch and looked at the common/gx1-base/*.
How do I add my board to the code tree?

It seems board specific codes which used to be in independent
files are now placed in #ifdef chain.  Should I add another #elif...?
That sounds not right.  Is there other way to refactor?
