X5777BXGABC: SIlicon 2.0

Hi

We are facing NOR Flash booting issue in our board which has Processor X5777BXGABC (silicon Rev 2.0) and it is migrated from X5777AXGABC (silicon Rev 1.1).

We are able to access the NOR flash and its data in both the silicon version boards  but booting is not happening in one board which has 2.0 Silicon .

We have made boot config setting such that it boots SD 1st or NOR as second boot device (SYSBOOT [5.:0] :000101).
