387 | Qemu is a software emulator which among other architectures also |
388 | can simulate a MIPS32 4Kc system. This patch adds support for the | |
389 | system architecture that currently is being simulated by Qemu. It | |
390 | will eventually be removed again when Qemu has the capability to | |
391 | simulate actual MIPS hardware platforms. More information on Qemu | |
392 | can be found at http://www.linux-mips.org/wiki/Qemu. | |
