JP11 is used to select the bus width of the external SDRAM.
When the jumper is at position 1-2, the external SDRAM is 32-bit wide and memory size
is 32MB. The memory consists of 2 chips in parallel, each 16MB and 16-bit wide.
When the jumper is at position 2-3, the external SDRAM is 16-bit wide and memory size
is 16MB. In this position one memory chip is disabled and only one chip is active (16MB
and 16-bit wide).
