Hello, guys!

I was so much impressed by Warner's talk at ASIA BSDCON held last
sunday, so I decided to try to run FreeBSD/mips on my BBR-4MG, a cheap
(about $30 in Japan) router which employs ADM5120P SoC.

Following modifications are needed to generate a kernel for
configuration "ADM5120". I have not tried it yet on the router, since
I have to build a serial console adapter and find a way to boot it.

By the way, I had to ask my friend who is a FreeBSD comitter to obtain
a set of mips2-jnpr source code. I tried accessing the archive via
p4web, but I found it not a very convenient method. Is there a nifty
way to access p4 server?

Regards,
Naoki Hamada
