+	  Make sure your ROM base does not include any file-header
+	  information that is prepended to the kernel.
+
+	  For example, the bootable U-Boot format (created with
+	  mkimage) has a 64 byte header (0x40).  So while the image
+	  you write to flash might start at say 0x20080000, you have
+	  to add 0x40 to get the kernel's ROM base as it will come
+	  after the header.
