/* Note, the board is populated with NOR flash and NAND flash.  By default, the
 * board is configured to boot from NOR flash.  Due to board-level logic, it is
 * not possible to access NAND flash in this configuration (contention on EMI
 * bus when using EMICS1#).  Furthermore, the logic to generate EMI_A26 seems to
 * be flawed, limiting access to NOR flash to 64MB.  The flash setup below
 * reflects these issues.
 *
 * Board mods are required to enable boot-from-NAND, but currently untested and
 * unsupported due to lack of a suitable board.
