No Connects on PowerPC BGA Packages

I intend on upgrading my PowerPC 60X device, can I generate a common BGA footprint and

route signals to pins which are labeled NC (no connects)?

A superset of the MPC60X BGA footprint was maintained across multiple parts to allow for a sin-

gle footprint to be used for multiple parts. In other devices labeling a pin as a 'NC' meant that the

user was required to not connect anything on that pin. This is not the case for the MPC60X foot-

print.
