-# --- ZyXEL header format ---
-# Original Version by Benjamin Berg <benjamin@sipsolutions.net>
-#
-# The firmware image prefixed with a header (which is written into the MTD device).
-# The header is one erase block (~64KiB) in size, but the checksum only convers the
-# first 2KiB. Padding is 0xff. All integers are in big-endian.
-#
-# The checksum is always a 16-Bit System V checksum (sum -s) stored in a 32-Bit integer.
-#
-# 4 bytes: checksum of the rootfs image
-# 4 bytes: length of the contained rootfs image file (big endian)
-# 32 bytes: Firmware Version string (NUL terminated, 0xff padded)
-# 4 bytes: checksum over the header partition (big endian - see below)
-# 32 bytes: Model (e.g. "NBG6617", NUL termiated, 0xff padded)
-# 4 bytes: checksum of the kernel partition
-# 4 bytes: length of the contained kernel image file (big endian)
-# rest: 0xff padding
-#
-# The checksums are calculated by adding up all bytes and if a 16bit
-# overflow occurs, one is added and the sum is masked to 16 bit:
-# csum = csum + databyte; if (csum > 0xffff) { csum += 1; csum &= 0xffff };
-# Should the file have an odd number of bytes then the byte len-0x800 is
-# used additionally.
-#
-# The checksum for the header is calculated over the first 2048 bytes with
-# the rootfs image checksum as the placeholder during calculation.
-#
-# The header is padded with 0xff to the erase block size of the device.
