Modified Files:
src/sys/arch/aarch64/aarch64 [netbsd-9]: cpu.c
src/sys/arch/arm/arm32 [netbsd-9]: cpu.c
src/sys/dev/fdt [netbsd-9]: fdtbus.c
Log Message:
Pull up following revision(s) (requested by martin in ticket #614):
sys/arch/aarch64/aarch64/cpu.c: 1.32
sys/arch/arm/arm32/cpu.c: 1.138
sys/dev/fdt/fdtbus.c: 1.31
When attaching the first fdtbus, use the root "comptabile" (or failing that:
"model") property to set the cpu model (in userland aka sysctl hw.model).
When attaching the first cpu, do not overwrite a cpu model if it already
had been set.
