+	Correct me if I'm wrong, folks, but the way I understand it
+	is this: Using DCACHE as initial RAM for Stack, etc, does not
+	require any physical RAM backing up the cache. The cleverness
+	is that the cache is being used as a temporary supply of
+	necessary storage before the SDRAM controller is setup. It's
+	beyond the scope of this list to expain the details, but you
+	can see how this works by studying the cache architecture and
+	operation in the architecture and processor-specific manuals.
+
+	OCM is On Chip Memory, which I believe the 405GP has 4K. It
+	is another option for the system designer to use as an
+	initial stack/ram area prior to SDRAM being available. Either
+	option should work for you. Using CS 4 should be fine if your
+	board designers haven't used it for something that would
+	cause you grief during the initial boot! It is frequently not
+	used.
+
+	CFG_INIT_RAM_ADDR should be somewhere that won't interfere
+	with your processor/board/system design. The default value
+	you will find in any recent u-boot distribution in
+	Walnut405.h should work for you. I'd set it to a value larger
+	than your SDRAM module. If you have a 64MB SDRAM module, set
+	it above 400_0000. Just make sure your board has no resources
+	that are supposed to respond to that address! That code in
+	start.S has been around a while and should work as is when
+	you get the config right.
