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 :-)
Yes, of course. We have to make different configuration files -- one for each board. But, do we really need different board directories with almost the same code in it?
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 :-)
Ex.: My current Stratix patch is based on the Cyclone board, because both boards are equal in context of u-boot basics need. Only the second serial i/f differs (not needed til now). So there will be more identicalness than differences for both boards.
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.
Best Regards, --Scott
