The majority of our targets provide a default value for the variable
SUPPORTED_DEVICES, which is used in images to check against the
compatible on a running device:
SUPPORTED_DEVICES := $(subst _,$(comma),$(1))
At the moment, this is implemented in the Device/Default block of
the individual targets or even subtargets. However, since we
standardized device names and compatible in the recent past, almost
all targets are following the same scheme now:
device/image name: vendor_model
compatible: vendor,model
The equal redundant definitions are a symptom of this process.
Consequently, this patch moves the definition to image.mk making it
a global default. For the few targets not using the scheme above,
SUPPORTED_DEVICES will be defined to a different value in
Device/Default anyway, overwriting the default. In other words:
This change is supposed to be cosmetic.
This can be used as a global measure to get the current compatible
with: $(firstword $(SUPPORTED_DEVICES))
(Though this is not precisely an achievement of this commit.)

WNDR4700 uboot has an issue with decompressing kernel with default dictionary size (-d23 which is about 8MB).
Limiting lzma dictionary lowers memory footprint and allows device to boot the kernel.
The highest bootable dictonary size is 18, choosing 16 for an extra safety margin.
Kernel size befor and after:
-d23: 2663665 Bytes
-d16: 2892757 Bytes
Kernel size increased by 230kB (9%)

Devices with PCIe-Switches like the WNDR4700, MR24 and WNDAP660
need to have the interrupts property specified in the device-tree
for the legacy pci interrupt signaling method to work.
If the proper interrupt value is not specified, the default INTA
IRQ 12 is taken for all devices. This is especially bad, if the
device is setup to use INTC, because these interrupts will not
be serviced.
Russell Senior reported his experience on the MR24:
"The symptom is client devices can't see the beacons.
Wifi ifaces appear, can scan and hear other networks,
but clients can't see the MR24's SSIDs."
(The interrupts-property on the WNDAP620 was optional since it
uses INTA by default. Likewise the MX60W is in the same category)

With the "real HZ" debate out of the way, let's actually
use the apm821xx's default upstream config file at
arch/powerpc/configs/44x/bluestone_defconfig. From what
I can tell, it sets NO_HZ (well, this platform was for
NAS, so this is a bit unexpected) and remove any specific
HZ_$VALUE symbol.
Sadly, Daniel Engberg didn't run any before/after netperf
tests, because it would have been such a slam dunk across
the boards. In case of the apm821xx the tcp tx/rx
performance improved ~14% (from 600Mbps to 700Mps).

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.
