+
+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!
+
