+Installation Instructions:
+--------------------------
+
+1. Put the s2 switch into the following position:
+
+	 1  0
+	------
+	|x   |
+	|   x|
+	|x   |	
+	|   X|	
+	------
+
+2. Connect to the serial console and to the BDI. Power on. On the
+   serial line, you should see:
+
+	PURPLE@1.2>
+
+3. Type '8'. No echo will be displayed. In response, you should get:
+
+	7A(pass)
+
+4. From BDI, enter command:
+
+	mmw 0xb800d860 0x0042c7ff
+
+5. Then, from BDI:
+
+	erase 0xB0000000
+	erase 0xB0008000
+	erase 0xB000C000
+	erase 0xB0010000
+	erase 0xB0020000
+
+	prog 0xB0000000 <u-boot.bin> bin
+
+6. Power off. Restore the original S2 switch position. Power on.
+   U-Boot should come up.
+
+
+
+Implementation Notes:
+---------------------
+
+Due to the RAM/flash bus arbitration problem the suggested workaround
+had to be implemented. It works okay. On the downside is that you
+can't really check whether 'erase' is complete by polling flash as it
+is usually done. Instead, the flash driver simply waits for a given
+time and assumes that erase then has passed. This behaviour is
+identical to what the VxWorks driver does; also, the same timeout (6
+seconds) was chosen. Note that this timeout applies for each errase
+operation, i. e. per erased sector.
