Partitioning notes:

Vendor firmware (based on CameoAP99) defines two additional partitions:
"mac" @0x3b0000, size 0x10000 and "lp" @0x3c0000, size 0x30000.

The "mac" partition stores LAN MAC address and hardware board name.
However, the vendor firmware uses addresses from "nvram" partition, and
the board name is used only for informational purposes in the Web
interface (included in the pages' header), not affecting the firmware
image check.

The "lp" partition is supposed to contain a "language pack" (which can
be used to add an additional language support to the Web interface) and
is flashed separately, using the vendor firmware upgrade page.

Since these partitions are absolutely useless for OpenWrt and
overwriting them doesn't prevent downgrading to obsolete vendor
firmware, this patch appends the valueable space to "firmware".

Installation instructions:

- Upgrade from OpenWrt ar71xx with "sysupgrade -f -n"
or
- Upload as a firmware update via the vendor Web-interface
or
- Connect UART and use "loady" to upload and run OpenWrt initramfs
  image, then sysupgrade from it (TFTP client doesn't work)
or
- Before powering up hold "reset" button and keep it pressed for about
  15 seconds after, then access fail safe Web server on 192.168.0.1 (the
  old uIP TCP/IP protocol stack is not compatible with modern Linux, the
  kernel, so you'll need to use some other OS to do this). Can be
  performed without a Web-browser too:
    curl http://192.168.0.1/cgi/index \
      -F Send=@openwrt-ath79-tiny-dlink_dir-615-e4-squashfs-factory.bin
