/* This file describes the header format for the single image. The image is broken
up into several pieces. The image contains this header plus 1 or more sections.
Each section contains a binary block that could be a kernel, filesystem, etc. The
only garentee for this is that the very first section MUST be executable. Meaning
that the bootloader will be able to take the address of the header start, add the
header size, and execute that binary block. The header has its own checksum. It
starts hdr_size-4 bytes from the start of the header.
