#     powerpc/64: Set default CPU in Kconfig
#     
#     Since 0069f3d14e7a ("powerpc/64e: Tie PPC_BOOK3E_64 to PPC_E500MC"),
#     the only possible BOOK3E/64 are E500, so no need of a default CPU
#     over the E5500.
#     When the user selects book3e, he must have a e500 compatible compiler,
#     and it won't work anymore with the default -mcpu=power64, see
#     commit d6b551b8f90c ("powerpc/64e: Fix build failure with GCC 12
#     (unrecognized opcode: `wrteei')")
#     
#     For book3s/64, replace GENERIC_CPU by POWERPC64_CPU to match the PPC32
#     POWERPC_CPU, and set a default mpcu value in Kconfig directly.
#     
#     When a user selects a particular CPU, he must ensure his compiler has
#     the requested capability. Therefore, remove hidden fallback, instead
#     offer user the possibility to say he wants to use toolchain default.
