There has been some modified device trees floating on forums to
make this device work, collect the work and integrate it into
OpenWrt so it hopefully works for users.

This adds support for the Gemini-based Verbatim S08V1901-D1
also known as Gigabit Ethernet Hard Drive and perhaps other
funny names.

This is patch is identical in form and purpose as the IB-4220-B
patch. We switch over to a single "firmware" partition.
All reference design-based machines are now converted and we can
drop the legacy set-up code.
It turns out that the reference design also uses the flash layout
with a 3072KB kernel so augment the sysupgrade to do the right
thing also here.

To optimize the flash usage and to make firmware upgrades
simpler, catenate the three firmware partitions "Kern",
"Ramdisk" and "Application" into one, and use all of this
for the combined MTD-splitted kernel+rootfs.
This works fine as long as the kernel is placed in the
beginning of this firmware partition and we leave the
RedBoot partition as is, so the boot loader still can load
the kernel from the first two RedBoot partitions.
Using the RedBoot partitions "as is" can be considered
harmful, because when you flash to a RedBoot partition the
file size is used for downsizing of the partition and make
firmware upgrades fail if they are larger than the RedBoot
partition size after flashing, despite there is actually
flash there. So overriding with fixed partitions is just
generally a good idea.

The firmware update file can get big, so instead of extracting
the whole file into the tmp folder potentially running out of space
and make the upgrade fail, stream from tar xvf -O directly to the
mtd write command.
Refactor the checking of partitions and the actual upgrade into
two steps when we are at it.

The Storlink reference designs sometimes fail upgrade because
not the entire partition is used, so the size isn't equal to
the actual flash space available for the partition.
Fix this by calculating the actual partition sizes by measuring
across the partition offsets instead.

The Gemini reference design-derived devices uses a partition
format which is predictable and we can exploit this to offer
some proper upgrade path.
The kernel for these contains a hack to use this partition
format unaltered by combining the partitions "Kern" and "Ramdisk"
to one image with all of the kernel+ramdisk in memory.
Then the "Application" which is used for the rootfs go into its
own partition.
Standard flash layout:
Kern 2048k |
Ramdisk 6144k | = 9216k
Application 6144k | = 15360k
Following the pattern of the factory image we create three
images named zImage, rd.gz and hddapp.tgz (these filenames
are misleading! They are just required by the old firmware.)
and flash each individually with "mtd" during upgrades.
Since the IB-4220-V has a different layout with a bigger kernel
space we parameterize this so we can handle this too. (More
fixes are needed for that device though.)
A way to upgrade older OpenWrt on these platforms to the latest
and greatest will be to copy the file
target/linux/gemini/base-files/lib/upgrade/platform.sh
to /lib/upgrade/platform.sh
on your running system and then run sysupgrade from the image
produced after this patch.
The script is picky to sanity check the partitions before
commencing upgrade.
This was tested with a full sysupgrade on the iTian SQ201.

This makes sysupgrade work on the D-Link DIR-685 after
initial factory install.
We create the platform.sh script to support sysupgrade
on more targets as we move on with sysupgrade support.
