+ * - 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.
