+ 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.
