[PATCH 1/4] cpu: Rename {powerpc, ppc} => ppc64 (filesystem)

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The driver only supports VIR_ARCH_PPC64 and VIR_ARCH_PPC64LE.

Just shuffling files around and updating the build system
accordingly. No functional changes.
