    7  * As upstream Linux does not support XIP, it cannot run in 8 MiB of HyperRAM.
    8  * Hence the 64 MiB of SDRAM on the sub-board needs to be enabled, which has
    9  * the following ramifications:
   10  *   - SCIF4 connected to the on-board USB-serial can no longer be used as the
   11  *     serial console,
   12  *   - Instead, SCIF2 is used as the serial console, by connecting a 3.3V TTL
   13  *     USB-to-Serial adapter to the CMOS camera connector:
   14  *       - RXD = CN17-9,
   15  *       - TXD = CN17-10,
   16  *       - GND = CN17-2 or CN17-17,
   17  *   - The first Ethernet channel can no longer be used,
   18  *   - USB Channel 1 loses the overcurrent input signal.
   19  *
   20  * Please make sure your sub-board matches the following switch settings:
   21  *
   22  *           SW6                SW6-1 set to SDRAM
   23  *  ON                          SW6-2 set to Audio
   24  * +---------------------+      SW6-3 set to DRP
   25  * | =   =   = = =       |      SW6-4 set to CEU
