   * Physical Memory Map:
   *   CS settings are defined by i.MX31:
   *     - CSD0 and CDS1 are 256MB each, starting at 0x80000000 and 0x9000000
   *     - CS0 and CS1 are 128MB each, at A0000000 and A8000000
   *     - CS2 to CS5 are 32MB each, at B0.., B2.., B4.., B6..
   *
   * HALE set-up of the bluetechnix board for now is:
   *   - 128MB DDR (2x64MB, 2x16bit), connected to 32bit DDR ram interface
   *   - NOR-Flash (Spansion 32MB MCP, Flash+16MB PSRAM), 16bit interface at CS0
   *		- S71WS256ND0BFWYM (and CS1 for 64MB S71WS512ND0 without PSRAM)
   *        the flash chip is a mirrorbit S29WS256N !
   *   - the PSRAM is hooked to CS5 (0xB6000000)
   *   - Intel Strata Flash PF48F2000P0ZB00, 16bit interface at (CS0 or) CS1
   *     - 64Mbit = 8MByte (will go away in the production set-up)
   *   - NAND-Flash NAND01GR3B2BZA6 at NAND-FC:
   *		1Gbit=128MB, 2048+64 bytes/page, 64pages x 1024 blocks
   *   - Ethernet controller SMC9118 at CS4 via FPGA, 16bit interface
   *
   * u-boot will support the 32MB nor flash and the 128MB NAND flash, the PSRAM
   * is not used right now. We should be able to reduce the SOM to NAND flash
   * only and boot from there.
