264 using a QEMU machine that targets a specific board, such as
265 mpc8544ds.
266
267 Unlike most e500 boards that target a specific CPU, this
268 platform works with any e500-family CPU that QEMU supports.
269 Thus, you'll need to make sure CONFIG_PPC_E500MC is set or
270 unset based on the emulated CPU (or actual host CPU in the case
271 of KVM).
