- * This code is based on emCORE, adds a couple of improvements thanks to
- * some extra features in Apple's ROM:
- * - Generic Im3Info header valid for all payloads. It is done by moving
- * the certificate to a fixed position (before data), and using a 'magic'
- * value (0x300) for signature offset.
- * - Some integer overflows in ROM make it possible to use the free space
- * available in Im3Hdr, resulting a maximum payload size of:
- * 128 KiB - 0x50 bytes (IM3INFO_SZ) - 700 bytes (CERT_SIZE).
