# Description: Adds a new OF-based serial driver instead of the bit-banging # one.
# Patch author: David Woodhouse <dwmw2@infradead.org>
# Upstream status: Well, this should replace the hacky workaround
# introduced in the powerpc-serial patch. not yet enabled though as i am
# unsure how this will work on PReP hardware.
