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.
this revision does not integrate the timer fix
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.
normaly yes but you need to update a few your config to have it working see comment on your patch
Thank you for your help
