Hm, I have to admit that I do not really like adding so many ifdefs into the tftp code and even into the state machine code. Can you give me a number on how much larger u-boot gets on your platform with and without the server support? If this is not too much, maybe we should include support always. If it is too much, maybe we can at least keep the state machine without ifdefs - if I see it correctly, this will only add at maximum a few bytes and STATE_RECW_WRQ will simply never be entered, correct?
Cheers Detlev
