I've Kernel 3.2.1 and it works. So I've made a clean-built of my 3.1.6 and works too. No idea why it failed before, but I'm going to disregard that for now. I think it's safe to conclude that the problem is an incompatibility between the FreeScale supplied 2.6.35.3-571 Kernel and the current version of U-Boot.
This is possible, but both are not mainlined..
Well, the current version of U-Boot is, obviously ;-). But indeed, the FreeScale supplied 2.6.35.3-571 Kernel is not. And there's no doubt that this is a bug in the FreeScale Kernel that wasn't triggered before because their U-Boot configured the clocks differently.
Unfortunately we cannot step up to another Kernel because we need the FreeScale power supply driver for our battery and that's not yet supported in later Kernel versions.
However, the logical approach is to port the power supply driver to the current kernel, and also to push it to mainline !
I fully agree. But that driver … it's scaring me! It's make out of - I kid you not - 12 files, containing well over 6000 lines of code. They had to give it it's own directory in .../drivers/power, something no other power driver ever needed.
