4baffa02ce ipq806x: switch to full dual-boot for the nbg6817 sysupgrade support
Instead of writing to the currently booted partition set, this
implements full dual-boot support for sysupgrade by always writing to
the other, currently inactive, partition set and toggling the dualflag
after a successful flash.

The currently active/ booted partition set is determined by parsing
/proc/cmdline for its rootfs parameter (supplied by the DTS), instead
of reading from the 0:DUAL_FLAG mtd, in order to prevent (potentially)
bricking both partition sets.

42fe7b3bbe ipq806x: request the first free loop device dynamically for the nbg6817 sysupgrade
Instead of hardcoding /dev/loop0, it's safer to query for the first
free loop device and assign that dynamically. While /dev/loop0 is a
reasonable assumption immediately following "losetup --detach-all",
detaching the mounted overlay is no longer strictly necessary once
dual-boot support has been added for the nbg6817.

b36cf0be30 ipq806x: use absolute the device path in $kernel for the nbg6817 sysupgrade
Harmonize the variable usage for $kernel and $rootfs to always contain
the full device path, instead of just its basename.

b6868e2f47 ipq806x: fix ZyXEL NBG6817 sysupgrade
Use the first found directory in the tar archive instead of relying on
a directory named according to the userspace boardname.

It allows to change the boardname without adding another compatibility
layer to the zyxel sysupgrade.

33f09cf151 ipq806x: convert to dt-based board-detection
Use the generic board detection method:
- Board name: First compatible string from the device tree
- Board model: Model property from the device tree

Change occurrences of board name in userspace by the compatible
string, and removed target specific board detection script

Replace the definition of SUPPORTED_DEVICES in Device/Default
to extract the dt compatible string from each device definition.
Additionally, for devices supported by lede-17.01, append
the value of BOARD_NAME to SUPPORTED_DEVICES in the device
definition.

9a221c6d69 ip806x: nbg6817: sysupgrade support both targets for kernel/ rootfs partitions
With this commit and the previous "nbg6817: don't hardcode the rootfs location
by using append-rootblock instead" applied, it is possible to boot- and
sysupgrade from both dual-boot sets (the primary mmcblk0p4+mmcblk0p5 or the
alternative mmcblk0p7+mmcblk0p8). However the sysupgrade support does not
toggle between both dual-boot sets between firmware upgrades so far.

The partition map of the eMMC used in the nbg6817 is:

Found valid GPT with protective MBR; using GPT.
Disk /dev/mmcblk0: 7471104 sectors, 3.6 GiB
Logical sector size: 512 bytes
Disk identifier (GUID): XXX
Partition table holds up to 12 entries
First usable sector is 34, last usable sector is 7471070
Partitions will be aligned on 2-sector boundaries
Total free space is 1 sectors (512 bytes)

   9          299042          823329   256.0 MiB   FFFF  bu1
  10          823330         7471069   3.2 GiB     FFFF  bu2

rootfs_data is the ext4 formatted overlay of the OEM firmware, LEDE
ignores it due to its (too) small size.

romd/ bu1 are initialized with zeroes (0x00) and unused.

bu2 is formatted with ext4 and used for streamboost and other optional
functionality by the OEM firmware, it is reformatted during factory
resets of the OEM firmware.

header/ header_1 contains version information for the corresponding
vendor firmwares installed to kernel/rootfs or kernel_1/ rootfs_1, the
format hasn't been completely reverse engineered so far and remains
left untouched by LEDE:

e4e984f2a0 treewide: use only board_name function to get name
Do not parse /tmp/sysinfo/board_name, /proc/cpuinfo or the device tree
compatible string directly. Always use the board_name function to get
the board name.

The admswconfig package still reads /proc/cpuinfo directly. The code
looks somehow broken and the whole adm5120 which uses this package
looks unmaintained. Leave it as it is for now.
