First, some build notes on the Silicon Turnkey eXpress XTc.This board has both 87x/88x procesor options at variousfrequencies.  The configuration file has some macros for settingthe clock speed, not all have been tested.  They all havea 10MHz input clock.  Please do not check in a configurationfile that selects a high speed not available on all processors.We chose the 66MHz core and bus speed, which should be OK onall boards.  If you have a processor, lucky you! :-)Just build a new configuration with that speed, checkthe macro configuration to ensure it's correct.  If themacro is updated, please check that in, but keep defaultprocessor speed.The board is likely to have more than 1Mbyte of NOR boot flash.It was also configured with a high boot vector (Dan's fault)so the standard 8xx mapping doesn't work well. We had to movethe addresses around a little bit so one copy would work.  Theflash got fragmented, and we are working on a better solution.There is an "xtc.cfg" floating around for the BDI2000, usethat for programming a new version of U-Boot.  You can probablyfind it on the Silicon Turnkey eXpress (www.silicontkx.com),Embedded Alley Solutions (embeddedalley.com), or Denx (denx.de)servers.The board will also have various SDRAM sizes, but the codeshould automatically determine the amount of memory.There are a couple of different board versions, visuallythey use different BGA or surface mount memory parts.  However,they are logically the same board.Now, some operational notes.The board has the option of sporting two FEC Ethernet ports.The second port isn't configured to be automatically availablebecause it would cause U-Boot to generate a board data structure(the bd_t) with multiple MAC addresses and be incompatible withstandard 8xx kernel builds.  You can use/test the second FECin U-Boot by assigning an 'eth1addr' and selecting the secondFEC as the port to use.Since this is just a development board and not a product, STxdoes not assign unique MAC addresses.  We just pilfer the"default" ones used by Wolfgang on some other boards.  Pleaseensure you assign unique MAC addresses when using these boards.The serial port baud rate is 38400, because that's the wayI like it :-)Thanks to Pantelis for lots of the work on this board port.Have Fun!	-- Dan15 August 2005
