Yes, we get so many of those that I tend to ignore them, assuming that
someone will pick it up and fix it.

Is this being compiled on a non-ppc/powerpc platform? That might explain it. UCC_GETH is defined in drivers/net/Kconfig, but UCC_FAST is defined in arch/powerpc/sysdev/qe_lib/Kconfig. So I supposed if you don't compile for ARCH=powerpc, then arch/powerpc/sysdev/qe_lib/Kconfig is never loaded?

If that's the case, then we're always going to have this problem with platform-dependent drivers in the /drivers/ directory. The ucc_geth driver depends on the "QE library", which is present only on some PowerPC processors, so we put the config options for the QE in arch/powerpc. But since ucc_geth is a standard Ethernet driver, it exists in drivers/net.
