+         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.
