[U-Boot] Boot count limit

[Felix Radensky]

Hi,

The current implementation of boot count limit feature
relies on the availability of registers/memory that preserve
their value across reboot. Unfortunately there's no such
thing my board. I was thinking of using u-boot environment
on NOR to store intermediate boot count value and clear it
in linux via fw_setenv. Is there any problem with this approach ?

Thanks.

Felix.
