+ADS GraphicsClient/ThinClient Single Board Computer
+
+For more details, contact Applied Data Systems or see
+http://www.flatpanels.com/products.html
+
+The original Linux support for this product has been provided by 
+Nicolas Pitre <nico@cam.org>.
+
+It's currently possible to mount a root filesystem via NFS providing a
+complete Linux environment.  Otherwise a ramdisk image may be used.  Use
+'make graphicsclient_config' before any 'make config'.  This will set up
+defaults for GraphicsClient/ThinClient support.
+
+The kernel zImage is linked to be loaded and executed at 0xc0200000.  
+Also the following registers should have the specified values upon entry:
+
+	r0 = 0
+	r1 = 29	(this is the GraphicsClient architecture number)
+
+Here is a tipical angel.opt option file if the kernel is loaded through
+the Angel Debug Monitor:
+
+----- begin angelboot.opt -----
+base 0xc0200000
+entry 0xc0200000
+r0 0x00000000
+r1 0x0000001d
+device /dev/ttyS1
+options "9600 8N1"
+baud 115200
+#otherfile ramdisk.gz
+#otherbase 0xc0800000
+exec minicom
+----- end angelboot.opt -----
+
+Then the kernel (and ramdisk if otherfile/otherbase lines above are
+uncommented) would be loaded with:
+
+	angelboot -f angelboot.opt zImage
+
+Here it is assumed that the board is connected to ttyS1 on your PC
+and that minicom is preconfigured with /dev/ttyS1, 9600 baud, 8N1, no flow
+control by default.
+
+If any other bootloader is used, ensure it accomplish the same, especially
+for r0/r1 register values before jumping into the kernel.
+
+
+Supported peripherals:
+- SA1100 LCD frame buffer (only 8bpp yet)
+- on-board SMC 92C94 ethernet NIC
+- SA1100 serial port
+- flash memory access
+- pcmcia
+- possibly UCB1200 audio (not tested yet)
+
+To do:
+- touchscreen driver
+- 16bpp frame buffer support
+- extra (external) serial port driver
+- some console keyboard support (maybe IR?)
+- everything else!  :-)
+
+Any contribution can be sent to nico@cam.org and will be greatly welcome!
