Is this somewhere reproducible?
Maybe we can try my patch from:

http://lists.denx.de/pipermail/u-boot/2008-October/041817.html

also for this board. The I2C deblocking is in i2c_make_abort () ...
If this works better, maybe we use this I2C deblocking mechanism as
new standard?

Couldnt use this board also the CFI driver?
