u-boot/include/configs/atc.h
Jon Loeliger 9c4c5ae3e1 * Patch by Jon Loeliger, Kumar Gala 2005-02-08 
- Convert the CPM2 based functionality to use new CONFIG_CPM2
    option rather than a myriad of CONFIG_MPC8560-like variants.
    Applies to MPC85xx and MPC8260 boards, includes stxgp3 and sbc8560.
    Eliminates the CONFIG_MPC8560 option entirely.  Distributes the
    new CONFIG_CPM2 option to each 8260 board.
