Dear Tom Rini,

But still, the kernel decided i2c probing is dangerous/unreliable, maybe we should follow, or at least allow boards to follow?
The kernel is in a very different situation - it is supposed to run on perfect hardware.
In U-Boot, we have to dead with green hardware that is in a completely unknown state, or with hardware that _might_ be broken in one way or another. For us tools doing low-level accesses are invaluable - even if they include the risk to hang a system.
Best regards,
Wolfgang Denk
