I understand this patch will need to be improved, but I am posting it now, so that others can possibly test it.
Just fyi: On the ALKML there are IPU patches from Sascha Hauer for the kernel. Applying Sascha's patches to the kernel and this patch to U-Boot makes the kernel crash with a NULL pointer [1].
I haven't looked into the details, wild guessing is that the U-Boot patch enables some interrupts the IPU driver isn't ready to handle before he's done his own initialization.
Note that this is only fyi.
Best regards
Dirk
