  49  * Physical Memory Map:
  50  *   CS settings are defined by i.MX31:
  51  *     - CSD0 and CDS1 are 256MB each, starting at 0x80000000 and 0x9000000
  52  *     - CS0 and CS1 are 128MB each, at A0000000 and A8000000
  53  *     - CS2 to CS5 are 32MB each, at B0.., B2.., B4.., B6..
  54  *
  55  * HALE set-up of the bluetechnix board for now is:
  56  *   - 128MB DDR (2x64MB, 2x16bit), connected to 32bit DDR ram interface
  57  *   - NOR-Flash (Spansion 32MB MCP, Flash+16MB PSRAM), 16bit interface at CS0
  58  *              - S71WS256ND0BFWYM (and CS1 for 64MB S71WS512ND0 without PSRAM)
  59  *        the flash chip is a mirrorbit S29WS256N !
  60  *   - the PSRAM is hooked to CS5 (0xB6000000)
  61  *   - Intel Strata Flash PF48F2000P0ZB00, 16bit interface at (CS0 or) CS1
  62  *     - 64Mbit = 8MByte (will go away in the production set-up)
  63  *   - NAND-Flash NAND01GR3B2BZA6 at NAND-FC:
  64  *              1Gbit=128MB, 2048+64 bytes/page, 64pages x 1024 blocks
  65  *   - Ethernet controller SMC9118 at CS4 via FPGA, 16bit interface
  66  *
  67  * u-boot will support the 32MB nor flash and the 128MB NAND flash, the PSRAM
  68  * is not used right now. We should be able to reduce the SOM to NAND flash
  69  * only and boot from there.
