[U-Boot] Boot count support on P1020

[Felix Radensky]

Hi,

I'd like to enable boot count feature on custom P1020 based board.
If my understanding is correct, the implementation requires some
register or memory location that preserves its value across reboots.

Can Freescale folks on the list please point to such location in P1/P2
SoCs.

Thanks a lot.

Felix.
