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
|
||||
can be found at http://www.linux-mips.org/wiki/Qemu.
