I found that U-boot 2009 does  much more detailed checking regarding the
CPU IDs. But also found discrepancies in the CPU reporting while running
U-boot 2009 using the BDI 2000. With the BDI2000 my CPU was detected as
8547E and with a standalone boot, U-Boot got 8548E.

See if the CPU is detected incorrectly while booting stand alone.
