Connect MPC85XX to the PowerPC build.
The kernel config file is KERNCONF=MPC85XX, so the usual procedure applies: 1. make buildworld TARGET_ARCH=powerpc 2. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX This default config uses kernel-level FPU emulation. For the soft-float world approach: 1. make buildworld TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 2. disable FPU_EMU option in sys/powerpc/conf/MPC85XX 3. make buildkernel TARGET_ARCH=powerpc TARGET_CPUTYPE=e500 KERNCONF=MPC85XX Approved by: cognet (mentor) MFp4: e500
