for the loongson 2f under features it reads:
"# Little endian MIPS III-compatible ISA" 
The "Little endian" puts the "el" in mipsel. mips and mipsel should only
differ in endianess. iirc there are even mips chips that can run in both modes 
depending
on initialization.

Lemote already created a version of gxemul capable of emulating the loongson 
2e. Hopefully
they will extend it to cover the 2f chip after which it could be used for 
running
an emulated install, making it easier to create compile farms and such.
