Summary: detect 0.1 silicon revision BF527-EZKIT as 0.0 version
Details:
detect 0.1 silicon revision BF527-EZKIT as 0.0 version on branch.
Then connected with 0.1 silicon revision BF527-EZKIT board, when kernel boots up, it says it is with 0.0 version chip.
It is an anomaly,and no workaround so far.
