[Qemu-devel] [PATCH] Add more devices to MIPS system emulation

[Aurelien Jarno <aurelien@aurel32.net>]

Hello all,

This patch, initially posted by Thiemo Seufer, adds more devices to the
MIPS system emulation, most importantly a RTC emulation which e.g. keeps
timestamps on a linux filesystem sane.

I have only modified it to use the patch I posted on the mailing list a
few minutes ago.
