At early boot, register r8 may contain an ATAGs or DTB pointer. When an appended DTB is found, its address is stored in r8, for extraction of the RAM base address later. However, if r8 contained an ATAGs pointer before, that pointer will be lost, and the provided ATAGs is no longer folded into the provided DTB. Fix this by leaving r8 untouched.

Let me know what you want to do. Thanks.Fixing the original is fine for me, of course. Thanks!Please submit a replacement for 8960/1, thanks.Done.
Gentle ping. This fix is still not present in linux-next for over 2 weeks...
