The directories ppc_64 are renamed as ppc in - config/ - lib/librte_eal/common/arch/ - lib/librte_eal/common/include/arch/ The EAL directories are not really renamed, but symbolically linked, because they will be moved with their new name in the next commits. If ppc_32 needs to be supported, it can be in the same directory. The arch directories arm and x86 are already covering both 32 and 64-bit sub-architectures.
