Hm, this might clash with the github PR:
"mpc85xx: add support for Freescale (NXP) P2020RDB"
<https://github.com/openwrt/openwrt/pull/1688> since
he seemingly disabled (commented it out, but left it in place)
the ramdisk feature for his p2020.

I've notified Pawel as well. I don't really think this is much of an
issue and both of you are currently familiar with the target
and the devices. I'm fine with just a short note whenever the feature
should be enabled for all targets or just those the individual 
subtargets and I'll then make the change locally.

Thanks,
Christian
