^ I still think by doing this you are risking overriding starting address
for all other generic systems. make 32r6_defconfig will load config files
of all boards.
Perhaps just provide an eqm5_defconfig will work better?
Thanks.

I think at a point you mentioned a way to remove the eyeq5 config board
from the 32r6_defconfig. It would be indeed a good solution.

So you mean a defconfig in direclty in arch/mips/configs/ and not
anymore in arch/mips/configs/generic ?

Unfortunately we don't have such mechanism for now :-(

Yep. I think that's the only fesiable way.
