pastebin):
Turns out there's hardware crypto acceleration on the DreamPlug's Marvell
Kirkwood processor, via the mv_cesa Linux kernel module, but it's not
supported by OpenSSL without some patches. I updated my Pastebin with the
info below, having set it up thanks to the following posts:
{{{

}}}
Here are the steps to make it work:
{{{
Assumptions and prerequisites:
- DreamPlug
- Debian Squeeze system
- GlobalScale stock (or other replacement-worthy) kernel
- build-essential, bzip2, devscripts, fakeroot & wget packages
- Boot partition (probably /dev/sda1) mounted on /boot
- Plenty of free space for sources
To get to this point, see:
http://code.google.com/p/dreamplug/downloads/list
Run as root (n.b. you are trusting plugapps.com):
wget --directory-prefix=/usr/src http://download.gna.org/cryptodev-linux
/cryptodev-linux-1.0.tar.gz
wget --directory-prefix=/usr/src
http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.38.7.tar.bz2
wget --directory-prefix=/usr/src http://plugapps.com/mirror/with-

wget --directory-prefix=/boot http://plugapps.com/mirror/with-
linux/2.6.38/2.6.38.7/dream-2.6.38.7-uImage
wget --directory-prefix=/boot http://plugapps.com/mirror/with-
linux/2.6.38/2.6.38.7/dream-2.6.38.7.config
wget --directory-prefix=/boot http://plugapps.com/mirror/with-
linux/2.6.38/2.6.38.7/sheeva-2.6.38.7-System.map
tar -C / -x -v -z --no-same-owner --no-same-permissions -f
/usr/src/sheeva-2.6.38.7-Modules.tar.gz
depmod -eF /boot/sheeva-2.6.38.7-System.map 2.6.38.7
tar -C /usr/src -x -v -j --no-same-owner --no-same-permissions -f
/usr/src/linux-2.6.38.7.tar.bz2
cp /boot/dream-2.6.38.7.config /usr/src/linux-2.6.38.7/.config
tar -C /usr/src -x -v -z --no-same-owner --no-same-permissions -f /usr/src
/cryptodev-linux-1.0.tar.gz
Reboot. In U-Boot, from the serial/JTAG console:
setenv mainlineLinux yes
setenv arcNumber 2659
printenv
Use `setenv _ENV_ _VALUE_` to change "uImage" to "dream-2.6.38.7-uImage".
Now:
saveenv
reset
Let the system boot. Now, as root:
make -C /usr/src/linux-2.6.38.7 oldconfig
make -C /usr/src/linux-2.6.38.7 prepare
make -C /usr/src/linux-2.6.38.7
Watch for this output, near the top, and hit ^C once you've seen the
second line:
HOSTLD scripts/mod/modpost
HOSTCC scripts/kallsyms
(All you need from this potentially lengthy `make` is modpost.) Continue:
rm /lib/modules/2.6.38.7/build
rm /lib/modules/2.6.38.7/source
ln -s /usr/src/linux-2.6.38.7 /lib/modules/2.6.38.7/build
ln -s /usr/src/linux-2.6.38.7 /lib/modules/2.6.38.7/source
make -C /usr/src/cryptodev-linux-1.0 install
depmod -eF /boot/sheeva-2.6.38.7-System.map 2.6.38.7
modprobe cryptodev
apt-get source openssl
apt-get build-dep openssl

As of 0.9.8o in Debian Squeeze, OpenSSL doesn't include /dev/crypto
acceleration support for AES192 or AES256 CBC, nor for SHA digests. There
are some older patches for this, but they don't apply cleanly to this
version.
