-First, some build notes on the Silicon Turnkey eXpress XTc.
-
-This board has both 87x/88x procesor options at various
-frequencies. The configuration file has some macros for setting
-the clock speed, not all have been tested. They all have
-a 10MHz input clock. Please do not check in a configuration
-file that selects a high speed not available on all processors.
-We chose the 66MHz core and bus speed, which should be OK on
-all boards. If you have a processor, lucky you! :-)
-Just build a new configuration with that speed, check
-the macro configuration to ensure it's correct. If the
-macro is updated, please check that in, but keep default
-processor 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 move
-the addresses around a little bit so one copy would work. The
-flash got fragmented, and we are working on a better solution.
-There is an "xtc.cfg" floating around for the BDI2000, use
-that for programming a new version of U-Boot. You can probably
-find 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 code
-should automatically determine the amount of memory.
-
-There are a couple of different board versions, visually
-they 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 available
-because it would cause U-Boot to generate a board data structure
-(the bd_t) with multiple MAC addresses and be incompatible with
-standard 8xx kernel builds. You can use/test the second FEC
-in U-Boot by assigning an 'eth1addr' and selecting the second
-FEC as the port to use.
-
-Since this is just a development board and not a product, STx
-does not assign unique MAC addresses. We just pilfer the
-"default" ones used by Wolfgang on some other boards. Please
-ensure you assign unique MAC addresses when using these boards.
-
-The serial port baud rate is 38400, because that's the way
-I like it :-)
-
-Thanks to Pantelis for lots of the work on this board port.
-
-Have Fun!
