Date: Fri, 03 Aug 2012 09:49:59 -0600 From: Ian Lepore <freebsd@damnhippie.dyndns.org> To: freebsd-arm@freebsd.org Subject: Complete patchset to support DreamPlug on Freebsd 8.x Message-ID: <1344008999.10571.8.camel@revolution.hippie.lan>
index | next in thread | raw e-mail
[-- Attachment #1 --]
Here is a complete patchset for running freebsd 8.x on a dreamplug.
I've verified that you can check out a clean 8.3-RELEASE or 8-stable
tree, apply this patchset, and end up with a bootable dreamplug with
SATA, USB, and both ethernet ports working.
The kernel config file is pre-set for nfs root using bootp config, but
contains several alternate ROOTDEVNAME lines that can be un-commented to
use a filesystem on a usb or sata drive as root.
(Note that this doesn't contain the fix for the disabled-icache-pages
bug, because that's not a dreamplug-specific thing; I'll post that
separately when it's ready.)

Add support to 8.x for GlobalScale Technologies DreamPlug units.
