Om2009 testing release 4

[Micael Henriksson]

The major reason for Qi's existence is maintainability. U-Boot has a
problem with all drivers for different HW being copied from the kernel
tree. When the kernel is updated/patched, the fixes don't
automagically appear in U-Boot.
Qi instead try to do as little as possible to be HW independant. Then
you can use a mini-kernel to make a boot menu. In this way you get all
the fixes from upstream development without the need of any manual
copy/paste and possible further debugging to get it to work.
