  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
