Currently, little endian is only supported on powernv and pseries, however, Kconfigs still allow us to include other platforms in a LE kernel, this may result in space wasting or even build error if some BE-only platforms always assume they are built for a BE kernel. So just modify the Kconfigs of BE-only platforms to remove them from being built for a LE kernel. For 32bit only platforms, nothing needs to be done, because CPU_LITTLE_ENDIAN depends on PPC64. For 64bit supported platforms, add CPU_BIG_ENDIAN to dependencies explicitly, so that these platforms will be disabled for LE [Suggested-by: Cédric Le Goater <clg@fr.ibm.com>].

The powersurge cpu boards can be used in the generation
|
|
of powermacs that have a socket for an upgradeable cpu card,
|
|
including the 7500, 8500, 9500, 9600. Support exists for
|
|
both dual and quad socket upgrade cards.
