+ADS GraphicsMaster Single Board Computer
+
+For more details, contact Applied Data Systems or see
+http://www.applieddata.net/products.html
+
+The original Linux support for this product has been provided by
+Nicolas Pitre <nico@cam.org>. Continued development work by
+Woojung Huh <whuh@applieddata.net>
+
+Use 'make graphicsmaster_config' before any 'make config'.
+This will set up defaults for GraphicsMaster support.
+
+The kernel zImage is linked to be loaded and executed at 0xc0400000.
+
+Linux can  be used with the ADS BootLoader that ships with the
+newer rev boards. See their documentation on how to load Linux.
+
+Supported peripherals:
+- SA1100 LCD frame buffer (8/16bpp...sort of)
+- SA1111 USB Master
+- on-board SMC 92C96 ethernet NIC
+- SA1100 serial port
+- flash memory access (MTD/JFFS)
+- pcmcia, compact flash
+- touchscreen(ucb1200)
+- ps/2 keyboard
+- console on LCD screen
+- serial ports (ttyS[0-2])
+  - ttyS0 is default for serial console
+- Smart I/O (ADC, keypad, digital inputs, etc)
+  See http://www.applieddata.com/developers/linux for IOCTL documentation
+  and example user space code. ps/2 keybd is multiplexed through this driver
+
+To do:
+- everything else!  :-)
+
+Notes:
+
+- The flash on board is divided into 3 partitions.  mtd0 is where
+  the zImage is stored.  It's been marked as read-only to keep you
+  from blasting over the bootloader. :)  mtd1 is
+  for the ramdisk.gz image.  mtd2 is user flash space and can be
+  utilized for either JFFS or if you're feeling crazy, running ext2
+  on top of it. If you're not using the ADS bootloader, you're
+  welcome to blast over the mtd1 partition also.
+
+- 16bpp mode requires a different cable than what ships with the board.
+  Contact ADS or look through the manual to wire your own. Currently,
+  if you compile with 16bit mode support and switch into a lower bpp
+  mode, the timing is off so the image is corrupted.  This will be
+  fixed soon.
+
+Any contribution can be sent to nico@cam.org and will be greatly welcome!
