This won't work, "powerpc/shared/console" is shared across powerpc FAMILYs:

[dufault at gen6 powerpc]$ grep -r shared/console .
./beatnik/bspbeatnik.yml:- bsps/powerpc/shared/console/console.c
./beatnik/bspbeatnik.yml:- bsps/powerpc/shared/console/uart.c
./haleakala/bsphaleakala.yml:- bsps/powerpc/shared/console/console.c
./haleakala/bsphaleakala.yml:- bsps/powerpc/shared/console/uart.c
./motorola_powerpc/obj.yml:- bsps/powerpc/shared/console/console.c
./motorola_powerpc/obj.yml:- bsps/powerpc/shared/console/uart.c
./mvme3100/bspmvme3100.yml:- bsps/powerpc/shared/console/console.c
./mvme3100/bspmvme3100.yml:- bsps/powerpc/shared/console/uart.c
./mvme5500/bspmvme5500.yml:- bsps/powerpc/shared/console/console.c
./mvme5500/bspmvme5500.yml:- bsps/powerpc/shared/console/uart.c
[dufault at gen6 powerpc]$

There is a missing FAMILY ("mvmexxxx") for the PowerPC VME boards "beatnik" (supports MVME5500 and MVME6100), "mvme3100", and "mvme5500" where we would put a "grp.yml" file for the console baud and other shared items on the VME boards.  There are still other FAMILY members outside of that non-existent VME family that wouldn't be addressed ("haleakala", "motorola_powerpc").  Adding FAMILY "mvmexxxx" is a valuable cleanup, but not one I can do now when I'm trying to cleanly-enough fix the default console baud and then move on to other pressing items.

I'll leave "uid: ../../optconsolebaud" in "spec/build/bsps/powerpc/{beatnik,haleakala,motorola_powerpc,mvme3100,mvme5500}/bsp*yml".
