[RFC,0/3] MIPS VirtIO Machine

Message

Hi there,

This patchset is to add a new machine type for MIPS architecture, which
is purely a VirtIO machine.

It is design to utilize existing VirtIO infrastures but also comptitable
with MIPS's existing internal simulation tools.

It should be able to cooperate with any MIPS core and boot Generic MIPS
kernel.

For testing purpose I've built little endian kernel[1] to work with this
machine with R4X00, loongson2f, octeon, mips32r2, mips64r2 and mips64r6. 

TODO:
- Documentation
- Test against big endian kernel
- nanoMIPS options

Thanks
