* Physical Memory Map:

* - 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.
