0007 * As upstream Linux does not support XIP, it cannot run in 8 MiB of HyperRAM.
0008 * Hence the 64 MiB of SDRAM on the sub-board needs to be enabled, which has
0009 * the following ramifications:
0010 * - SCIF4 connected to the on-board USB-serial can no longer be used as the
0011 * serial console,
0012 * - Instead, SCIF2 is used as the serial console, by connecting a 3.3V TTL
0013 * USB-to-Serial adapter to the CMOS camera connector:
0014 * - RXD = CN17-9,
0015 * - TXD = CN17-10,
0016 * - GND = CN17-2 or CN17-17,
0017 * - The first Ethernet channel can no longer be used,
0018 * - USB Channel 1 loses the overcurrent input signal.
0019 *
0020 * Please make sure your sub-board matches the following switch settings:
0021 *
0022 * SW6 SW6-1 set to SDRAM
0023 * ON SW6-2 set to Audio
0024 * +---------------------+ SW6-3 set to DRP
