A new NetBSD port is coming (WIP)!
Hello NetBSD guys,
First, sorry for cross-list posting, I didn't really know where this
e-mail belong to.
Here is a small notice to let you know that I am in the process of
adding support for the LatticeMico32 CPU  and the Milkymist SoC 
to NetBSD 6 kernel.
LatticeMico32 (LM32) is an Open Source softcore (CPU which runs as
gateware inside a FPGA) developed by Lattice Semiconductor.
LM32 can be used on several FPGA models from several FPGA vendors
(Xilinx (Virtex 4, Spartan 3, Spartan 6 etc) Lattice, Altera (DE0 board)
and maybe more).
Originally this CPU did not have any kind of MMU. Last year I developed
an MMU for LM32 with the help of the Milkymist community (and a lot of
help from Michael Walle in particular).
The LM32 softcore CPU is used in the Open Source Hardware Milkymist SoC
which is the main component of the Milkymist One board .
For now, the Milkymist SoC/board runs an embedded OS (RTEMS) and is able
to run ucLinux (no-mmu) as well.
The first goal of my work is to make NetBSD kernel (and userland) run on
the Milkymist One board (thus on the Milkymist SoC with the modified
MMU-enabled LM32 cpu).
The second goal - which explains why I am contacting you instead of
working off-the-record on my own - is to integrate my port (when
finished and fully working) upstream in the NetBSD source tree :)
So I guess I need to say hello and open my code to comments and reviews
in order to do things in a proper and clean way that will allow the
integration upstream in the future.
For now I just wanted to break the silence and to at least make you
aware of my ongoing work :)
See you around, I may ask a few questions from time to time when I feel
lost about some NetBSD internal stuff if you don't mind ;)
Don't hesitate to ask me about what I'm doing/how I'm going it and what
the hardware is capable of.
