That would be a good idea. > It may still be worth doing something like this, but would a middle > groun of making it loop something like a 100 times be an option? Using 10 is already the middle ground between the existing code using 1000 and the pre-1999 behaviour of checking on every iteration, i.e. 1. Until an U-Boot upgrade is available, using 100 would cause a delay of 8 seconds between timeout checks.
