Tom Rini 6e7df1d151 global: Finish CONFIG -> CFG migration At this point, the remaining places where we have a symbol that is defined as CONFIG_... are in fairly odd locations. While as much dead code has been removed as possible, some of these locations are simply less obvious at first. In other cases, this code is used, but was defined in such a way as to have been missed by earlier checks. Perform a rename of all such remaining symbols to be CFG_... rather than CONFIG_...

Overview
--------
The LS1046A Freeway Board (iFRWY) is a high-performance computing,
evaluation, and development platform that supports the QorIQ LS1046A
LayerScape Architecture processor. The FRWY-LS1046A provides SW development
platform for the Freescale LS1046A processor series, with a complete
debugging environment. The FRWY-LS1046A  is lead-free and RoHS-compliant.
