 'make thinclient_config' before any 'make config'.  This will set up
 defaults for 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 = 24	(this is the ThinClient 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 0x00000018
+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 ThinClient 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
 - possibly UCB1200 audio (not tested yet)
 
 To do:
 - touchscreen driver
-- flash memory access
 - 16bpp frame buffer support
 - extra (external) serial port driver
 - pcmcia
