These config symbols are for setting -mcpu. Kernels built with CONFIG_GENERIC_CPU should also work on e5500/e6500. The problem is that CONFIG_PPC_QEMU_E500 doesn't select E500 (I didn't notice it before because usually CORENET_GENERIC is enabled as well). Note that your patch, by eliminating the dependency on E500, would make it possible to build a book3s kernel with E5500_CPU/E6500_CPU, which doesn't make any sense. -Scott
