So digging a bit deeper - since I have am arm compiler after all - I
note that 'sizeof(detailed_timings)' is 88.

Which is completely wrong. It should be 72 bytes (an array of 4
structures, each 18 bytes in size).

I have not dug deeper, but that is clearly the issue.

Now, why that only happens on that spear3xx_defconfig, I have no idea.
