+	 *
+	 * 0x1000	YAMON functions
+	 * 0x5000	YAMON code

+	 *
+	 * The User's Manual unfortunately does not say where does the SDRAM
+	 * portion used by YAMON end.
+	 *
+	 * Looking into the YAMON 02.21 sources, it looks like the first free
+	 * address is computed dynamically and depends on the size of the YAMON
+	 * image. From the YAMON binary, it appears to be 0xc0d50 or roughly
+	 * 772 KiB for that particular version.
+	 *
+	 * Linux is linked to 1MiB which seems to be a safe bet and a reasonable
+	 * upper bound for memory taken by YAMON. We will use it too.
