Philippe Mathieu-Daudé c3a09ff68d hw/mips/fuloong2e: Fix typo in Fuloong machine name
We always miswrote the Fuloong machine... Fix its name.
Add an machine alias to the previous name for backward
compatibility.

.. _MIPS-System-emulator:
MIPS System emulator
--------------------
Four executables cover simulation of 32 and 64-bit MIPS systems in both
endian options, ``qemu-system-mips``, ``qemu-system-mipsel``
``qemu-system-mips64`` and ``qemu-system-mips64el``. Five different
machine types are emulated:
- A generic ISA PC-like machine \"mips\"
- The MIPS Malta prototype board \"malta\"
- An ACER Pica \"pica61\". This machine needs the 64-bit emulator.
- MIPS emulator pseudo board \"mipssim\"
- A MIPS Magnum R4000 machine \"magnum\". This machine needs the
64-bit emulator.
The generic emulation is supported by Debian 'Etch' and is able to
install Debian into a virtual disk image. The following devices are
emulated:
- A range of MIPS CPUs, default is the 24Kf
- PC style serial port
- PC style IDE disk
- NE2000 network card
The Malta emulation supports the following devices:
- Core board with MIPS 24Kf CPU and Galileo system controller
- PIIX4 PCI/USB/SMbus controller
- The Multi-I/O chip's serial device
- PCI network cards (PCnet32 and others)
- Malta FPGA serial device
- Cirrus (default) or any other PCI VGA graphics card
The Boston board emulation supports the following devices:
- Xilinx FPGA, which includes a PCIe root port and an UART
- Intel EG20T PCH connects the I/O peripherals, but only the SATA bus
is emulated
The ACER Pica emulation supports:
- MIPS R4000 CPU
- PC-style IRQ and DMA controllers
- PC Keyboard
- IDE controller
The MIPS Magnum R4000 emulation supports:
- MIPS R4000 CPU
- PC-style IRQ controller
- PC Keyboard
- SCSI controller
- G364 framebuffer
The Fuloong 2E emulation supports:
- Loongson 2E CPU
- Bonito64 system controller as North Bridge
- VT82C686 chipset as South Bridge
- RTL8139D as a network card chipset
The mipssim pseudo board emulation provides an environment similar to
what the proprietary MIPS emulator uses for running Linux. It supports:
- A range of MIPS CPUs, default is the 24Kf
- PC style serial port
- MIPSnet network emulation

nanoMIPS System emulator
~~~~~~~~~~~~~~~~~~~~~~~~
Executable ``qemu-system-mipsel`` also covers simulation of 32-bit
nanoMIPS system in little endian mode:
- nanoMIPS I7200 CPU
Example of ``qemu-system-mipsel`` usage for nanoMIPS is shown below:
Download ``<disk_image_file>`` from
https://mipsdistros.mips.com/LinuxDistro/nanomips/buildroot/index.html.

Start system emulation of Malta board with nanoMIPS I7200 CPU::
qemu-system-mipsel -cpu I7200 -kernel <kernel_image_file> \
-M malta -serial stdio -m <memory_size> -hda <disk_image_file> \
-append "mem=256m@0x0 rw console=ttyS0 vga=cirrus vesa=0x111 root=/dev/sda"
