Hi All,

I agree with all of the comments I have seen so far WRT
Nios configuration issues. My primary motivation is to make
sure Nios users new to u-boot, can build a __working__ version
of u-boot by simply:

    $ make DK1C20_config | DK1S10_config | etc.
    $ make

As long as this holds true, I'm happy :-)

u-boot has a clever mechanism we can use to avoid code
duplication by using the VENDOR make variable. A good
example is in board/siemens: the SCM and CCM boards
both share common code.

Since this mechanism is supported ... and it is being used by
other board families, we can do the same. It's a bit more
work ... but I believe it will satisfy everyone :-)

Understood. We can create board/altera_nios (or some other
meaningful name) and take advantage of the VENDOR variable
to accommodate common code. Stephen & Patrice, please let
me know your thoughts.
