Recently, upgrade device autodetection has been added to the mvebu target.
This exposes some shortcomings of the generic export_bootdevice function,
e.g. on the Turris Omnia: export_bootdevice silently reports the root
partition to be the boot device. This makes the sysupgrade process fail at
several places.
Fix this by clearly distinguishing between /proc/cmdline arguments which
specify the boot disk, and those which specify the root partition. Only in
the latter case, strip off the partition, and do it consistently.
root=PARTUUID=<pseudo PARTUUID for MBR> (any partition) and root=/dev/*
(any partition) are accepted.
The root of the problem is that the *existing* export_bootdevice in
/lib/upgrade/common.sh behaves differently, if the kernel is booted with
root=/dev/..., or if it is booted with root=PARTUUID=...
In the former case, it reports back major/minor of the root partition,
in the latter case it reports back major/minor of the complete boot disk.
Targets, which boot with root=/dev/... *and* use export_bootdevice /
export_partdevice, have added workarounds to this behaviour, by specifying
*negative* increments to the export_partdevice function.
Consequently, those targets have to be adapted to use positive increments,
otherwise they are broken by the change to export_bootdevice.

sunxi sysupgrade was based on the x86 implementation; sync fixes and other
changes from the current x86 version:
x86: fix sysupgrades on disks with 4k block size
x86: sysupgrade: move partition table change check to platform_check_image
x86: sysupgrade: refactor platform_do_upgrade
x86: sysupgrade: explicitly rescan disk after writing partition table

When existing partitions are retained, the dd call writing the uboot image
in the space before the first partition was accidentally writing the whole
image, making the code for individual partitions redundant. Limit the copy
to 1016KiB (the first 8KiB are skipped, and the first partition starts at
1024KiB).
In addition, conv=notrunc is replaced with conv=fsync. It seems this was an
oversight, as notrunc doesn't make sense for block devices and all other dd
commands use conv=fsync.

To achieve this, device tree compatible string was used as boardname and
the value of it will be checked against supported_devices list.
It should be noted that we do not distinguish between
sun5i-a13-olimex-som and sun5i-a13-olinuxino as they share the same dts
file.
The other thing is that we need to gunzip the generated firmware to do
fwtool check.
