The initialziation of the memory controller (and things like testing
and sizing available memory) have to be done by the firmware on your
board, so look in your firmware sources.
For additional chip selects, you can of course add the necessary
BRx/ORx initialization in the init function of the device driver that
will be accessing this hardware.
Best regards,

I think it's a new feature. Don't tell anyone it was an accident. :-)
