BTW, I am willing to make the change so that the code uses
the symbols:


as suggested.  I like it.

However, now I need answers to the following question:  Do you want
me to retrofit code into all the Config files to #define CONFIG_HAS_ETHx
where it currently also has CONFIG_ETHxADDR defined, or where the code
has a board name even though a CONIG_ETHxADDR is not defined too?

Happy to do this, just realize that to be backwards compatible
with existing config files, I'll have to change many config files.
I can not test them all.  I can test the 4 I have in front of me.

FYI, I am also willing to remove the #ifdef conditionality from
the bd_t structure around these ETH addr fields as well, but with
the caveat that it changes other people's bd_t structures and
potentially messes up their Linux interfaces.  Again, I can't
test all that either...
