Booting NetBSD/evbarm on QEMU (IntegratorCP)

[Sergio López <slp%sinrega.org@localhost>]

Hi,

As part of a personal project to get familiar with the ARM
architecture, I've been working on getting NetBSD/evbarm to boot on
QEMU. I've based my work on the present support for ARM Integrator
evaluation board.

Right now, it boots and its able to mount root from ramdisk and NFS
(though I've only tested the latter). This emulated board also
includes a PL181 device for memory cards, but is not yet supported.

You can find the patch here:

And a ready to use image here:

http://blogs.nologin.es/slopez/uploads/netbsd.gz.ub

It can be used with something like this: "qemu-system-arm -M
integratorcp -cpu arm1136 -m 128m -kernel netbsd.gz.ub -serial stdio
-net nic -net tap". This image doesn't contain a ramdisk, so you'll
need an NFS with NetBSD/evbarm root, and a properly configured DHCP
server.

Please note that I'm not familiar with the NetBSD contributing
process, so if you think it could be convenient to commit this work to
the repository, please tell me which changes to the code and/or
administrative tasks must be done to meet your standards.

 Thanks.
