Well, it is not used by U-Boot itself, but when you have a big Linux kernel it starts overwriting itself when you uncompress it to address 0.
software issue. Maybe u-boot should give some warning about that ( if it's the cause, not yet sure ). But that's off topic here.
U-Boot does not know the uncompressed size in advance. And anyway - it's a pilot error :-) In modification of anmother famous quote: "U-Boot was not designed to stop you from doing stupid things, because that would also stop you from doing clever things."
Now, I'm just looking forward for new BestComm code, to get AC97 and IDE DMA running ( quite slow and CPU intensive right now ... ).
