My value was at 1000000. Switching back to 1000 didn't solve my problem,
but instead causes erase and write operations on nand flash to timeout
as well. My u-boot was built on commit
03bab0091948196b9558248684c04f60943ca4b5 of the at-91 tree. Rebasing it
to the current version with the changed timer code caused u-boot to not
boot at all on my hardware. I just made a simple board port and didn't
change much, but I add my diff against u-boot-at91 anyway. It should
work on the Atmel Board as well, but I don't own any.
Thank you for your help
