Wolfgang, Philippe, Peter and others,

I made some mistakes when dividing the whole patch into several
logical sets of individual patches. The u-boot.arm926ejs.patch was
totally wrong. I apologize here for my carelessness.

The patches attached today is againt the latest CVS (1.1.3) and I've
tested to make sure there are no more such errors. Wolfgang, please be
aware of the errors in the previous patches submitted a month ago
(Dec. 20, 2004) and delete it from your backlog if possible.

Philippe and Peter, sorry for the trouble it might cause and waste
your time. If having time, you can validate the patches on your
platform, especially the patch for ARM926EJS.

Peter, thanks for the patch for the wrong configured timer value. I
cannot understand why I set it to 0x8C instead of 0x8A at that moment.
However please be aware that that patch was kinda obsolete. The better
way to fix CFG_HZ issue (thus timer issue) is implemented in the
patches attached today, which set CFG_HZ to 1000.

Best regards,
