Ulf, I was thinking this already.. I just thought that I was missing something which is why I asked the questions. I'll send a patch to the group for review later.

If you don't explicitly 'saveenv' there is no 'ver'
variable to read
from linux... And it can't be good for the flash to force u-boot to
save on every
boot.
So if I update (from linux for example) 'ver' doesn't get
updated unless
u-boot is doing a saveenv on every boot...
Maybe saving the environment (with ver) should be forced if "ver" is not the same as the U-Boot version.
