Dear Prafulla Wadaskar,

If possible, the memory controller should be configured such that the
banks are mapped at different addresses then, so that they again form
a contiguous RAM area.

If this is not possible (because the bank base addresses cannot be
adjusted), then we have a problem.

Best regards,
