src/sys/arch/evbsh3/conf: NEXTVOD files.nextvod mk.nextvod std.nextvod
src/sys/arch/evbsh3/nextvod: clock_machdep.c nextvod.c stasc.c
Log Message:
Add placeholders/boilerplate for NextVoD.
STMicroelectronics support needs to be written for both the CPU and
devices. This config and related files is absolute bare bones to get
a scaffolding kernel to compile to actually work on that support.
Don't hold your breath.
