Hi,
I'd like to help a little bit with the installation documentation, at least with the boards I have and can verify the instructions.

Do I just log in and edit the wiki page?
Or would it be better to send it here, or to pwhalen (who looks like he does the edits)?

Just incase it's to send things here.  In the manual steps there are a few things that would be good to change/add.

BeagleBone:
The uboot directory has changed, so it is no longer beaglebone, but am335x_boneblack.  Please change
  /usr/share/uboot/beaglebone/
to
  /usr/share/uboot/am335x_boneblack/

PcDuino:
The PcDuino family have the Allwinner A20 chipset, and fall in the same instructions as Banana Pi and CubieBoard.  But their names, and their uboot names, are so horribly long.  But it would be nice to have them in there somehow.  Could we possibly put them in the TARGET= line?
Something like
TARGET= # Bananapi , CubieBoard , Cubieboard2 , Cubietruck
# Linksprite_pcDuino , Linksprite_pcDuino3 , Linksprite_pcDuino3_Nano

Thanks
Troy Dawson
