From d5e54913433fff89609adfc4b96fefcf807a9030 Mon Sep 17 00:00:00 2001 From: David Gibson Date: Wed, 5 Nov 2008 14:20:17 +0000 Subject: powerpc: udbg-based backend for hvc_console This adds a new backend for the hvc console based on the low-level udbg callbacks. This effectively implements a working runtime console in terms of the simple udbg primitives. This is kind of a hack - since udbg isn't something you really want to be using routinely - but it's really useful during bringup. This can be used to quickly implement a userspace-usable console while you're working on a proper driver for whatever console I/O device the hardware has. Or, it can be used to avoid writing a full blown tty/console driver entirely for quick-and-dirty I/O hardware that will later be replaced by something else.
