I searched for some space on this CPU for implementing this feature, but could not find any (at least 4 bytes = 1 register), which not lost his value on a reset of this CPU.
There is reset counter register on Kirkwood which counts the time for which H/w Reset is pressed-n-hold. This is generally used to trigger "Factory Reset" Kind of function using reset key.
I don't think you are searching for the same. Do you?
No, he doesn't. He needs a register that is guaranteed to keep it''s values across a processor reset.
BTW: What's your end use case?
The boot counter counts the number of (failed) boot attempts (i. e. processor resets minus one) after power on. See http://www.denx.de/wiki/view/DULG/UBootBootCountLimit
