Dreamplug serial console, plus faster boot

Some months ago, I put my hands on a Dreamplug device. I haven't done too much with it, just put arch on it. Now I decided to log in again, and play around with it. First I need to log in with the serial console. In order to do that, I need to be able to use my serial (ttyUSB0) as a simple user. I first added myself to the dialout group:

sudo gpasswd dialout -a matelakat

And as I don't want to log on/off, I activated the group memberships:

newgrp dialout

And off you go, I just had to start minicom:

Let's make booting a bit faster. See here. I will make a note of my original bootcommand here (The whole stuff needs to be one line!)

bootcmd=setenv ethact egiga0; ${x_bootcmd_ethernet}; setenv ethact egiga1;
 ${x_bootcmd_ethernet}; ${x_bootcmd_usb}; ${x_bootcmd_kernel};
 setenv bootargs ${x_bootargs} ${x_bootargs_root};
 bootm 0x6400000;

And so it is modified to:

${x_bootcmd_usb}; ${x_bootcmd_kernel};
 setenv bootargs ${x_bootargs} ${x_bootargs_root};
 bootm 0x6400000;

With this:

Marvell>> setenv bootcmd '${x_bo...

And save the stuff:

Marvell>> saveenv

And reset

Marvell>> reset

So that the device will boot significantly faster.
