Then we need to clean up other part of the code: system_rev should be
not declared globally in the file and must be removed. In the same time,
get_board_rev() should be changed. It seems it is in any case wrong,
because it returns the same value, and this means get_cpu_rev().

As this is a cpu revision and not a board revision, it is not correct.
If the board revision cannot be determined correctly at runtime, we
should return a fixed value. but certainly not the cpu revision.

Best regards,
Stefano Babic
