Dear Tom,

Is there any reason for not chosing the more standard 5 second delay?
Ok, so let's go with 3 seconds then ;-)
There's a pretty even distribution of 1 3 and 5 second delays (with a few 10s, 2s and 6s). If they want 1, let them have 1, it's not hard to break into, you have U-Boot starting + 1sec.
The question is who "they" are. My vote is for 5 :-)
A quick AWK oneliner in include/configs finds this statistics:
Value Count -1: 49 0: 12 1: 59 2: 30 3: 150 5: 175 6: 14 10: 38 20: 1
[And this does not take into account that for example amcc-common.h which defines a value of 5 is included by 28 other board config files...]
Best regards,
Wolfgang Denk
