+	# Now setup SDRAM.  This is tricky and configuration is very important for reliability!  The current calculations
+	# are based on 2 x Micron MT48LC16M16A2-75 memory (4 M x 16 bit x 4 banks).  If you use this file as a reference
+	# for a new board that uses different SDRAM devices or clock rates, you need to recalculate the value inserted
+	# into the SDRAM_CR register.  Using the memory datasheet for the -75 grade part and assuming a master clock
+	# of 132.096 MHz then the SDCLK period is equal to 7.6 ns.  This means the device requires:
+	#
+	#	CAS latency = 3 cycles
+	#	TXSR = 10 cycles
+	#	TRAS = 6 cycles
+	#	TRCD = 3 cycles
+	#	TRP = 3 cycles
+	#	TRC = 9 cycles
+	#	TWR = 2 cycles
+	#	9 column, 13 row, 4 banks
+	#	refresh equal to or less then 7.8 us for commercial/industrial rated devices
+	#
+	#	Thus SDRAM_CR = 0xa6339279
