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