* This implements simple platform support for PowerPC 44x chips. This is
* mostly used for eval boards or other simple and "generic" 44x boards. If
* your board has custom functions or hardware, then you will likely want to
* implement your own board.c file to accommodate it.

/* This is the list of boards that can be supported by this simple
* platform code. This does _not_ mean the boards are compatible,
* as they most certainly are not from a device tree perspective.
* However, their differences are handled by the device tree and the
* drivers and therefore they don't need custom board support files.
*
* Again, if your board needs to do things differently then create a
* board.c file for it rather than adding it to this list.
