Is RPC dead and can we send it off to Valhalla? Support for ARMv3 was removed in gcc-9, so there is a Kconfig dependency on the compiler version to prevent broken builds. You can use the gcc-8 builds from kernel.org[1]. Russell still uses this machine with an older compiler though, and I guess he will keep using newer kernels for as long as gcc-8 can build them. No idea which ethernet card he uses, there are at least three of them.
