[Jia Jianwei]

      I use the code of VT8623 to active DDR RAM, but only BANK 0 is working, BANK 1 is not
working.If I only use BANK0 or BANK1, it is working well.  I tried to active it twice with
only one bank setting, yes , It's working with memtest, but, PCI burst does not work,
All PCI bus master device do not work.
Anybody can tell me Why?

Best Regards,
