Thanks again for your replies.
I downloaded the 3.9-rc5 kernel from kernel.org
and it seems to have armada 370 support
(which is my mirabox) so I started with the .config from the 188.8.131.52 debian mirabox
kernel and did "make olddefconfig", then make, etc.
"make uImage" complained about a missing LOADADDR so I did "make
LOADADDR=0x0008000 uImage". Everything compiled nicely and then I booted with it, and
the bootlog is as follows:

It's probably trying to tell you that it can't find support for your machine id
In my .config are (amongst others):
# CPU Core family selection
# CONFIG_ARCH_MULTI_V6 is not set
# CONFIG_ARCH_MULTI_CPU_AUTO is not set
# Marvell SOC with device tree
# CONFIG_MACH_ARMADA_XP is not set

no, not that I know of.
Compile the kernel as zImage, then the device
tree that comes with Linux (arch/arm/boot/dts/armada-370-mirabox.dts) to a dtb and then
load both from u-boot? You just pass the dtb as 3rd parameter to the bootz command. If you
run without an initrd, just pass "-" to bootz to tell it you don't want
I'd assume that should just work, and should also get you something properly working
with openSUSE 12.3. No guarantees that all your hardware components will be supported by
the upstream code however :). Traditionally, we've had quite a bit of trouble getting
I think I understand what you write (except for the dts/dtb) but my uboot loader
doesn't have a bootz, so I don't know how to continue with this suggestion.
Then use bootm, that works just as well if you create a uImage. Enabling bootz support in
u-boot also isn't overly hard, but let's go one step at a time.
In the old days of ARM (read: last year), there used to be machine IDs that u-boot pass on
to the kernel to identify which board a particular machine identifies as. Linux then
contains a C file describing what hardware looks like in that board. This means that every
new board needed a new kernel, even if only very little changed to another, already
This scheme was deprecated by device trees. For most modern boards, you can now just pass
in a device tree (dtb) into the kernel which describes what the C file used to describe,
but in as data rather than code. That allows for a lot more flexibility.
For your Mirabox, it looks as if support for the machine ID based approach simply never
made it upstream, so you have to pass in a device tree to get Linux to actually run
anything sensible on your board.
You can compile dts files into dtb files using the dtc command line tool. Pass the dtb
into your bootm command as 3rd parameter. Also make sure you have your console= setting
correct. Then your board should boot with 3.9 :).
