Thank you Rafal for adding this!  Our proposal is to replace with BCMBCA (and I
have a WIP patchset for that). Agree there are pros and cons using
single general config versus individual chip config(we have 15 BCA chip
now in the kernel) as you and Florian were discussing in another
thread. But we feel
single config has more advantage as it can produce the same image to
test all the chips and it is easier to maintain.  That is why we moved BCM63138
ARCH_BCM_63XX to ARCH_BCMBCA.
