- Qemu is a software emulator which among other architectures also
- can simulate a MIPS32 4Kc system. This patch adds support for the
- system architecture that currently is being simulated by Qemu. It
- will eventually be removed again when Qemu has the capability to
- simulate actual MIPS hardware platforms. More information on Qemu
