Both :-)
As you can see, it's not a normal multi_v7 boot: it's a multi_v7 + big endian. So that's a new thing Kevin and I have been working on over the last few weeks: since we support big endian on Marvell EBU platforms, I asked Kevin if it was possible to add it to the board farm. And so he did.
It works fine on the Mirabox. However, on the OpenBlocks, there is still a small problem: the OpenBlocks has 1 GB of soldered RAM and some of them come with 2 additional GBs of RAM on a DIMM slot. In the kernel DT, we specified a memory size of 3 GB.
On little endian configurations, as long as ATAGS_DTB_COMPAT is used, it works fine in all situations: the memory size of 3 GB indicated in the DT will be overridden by whatever the bootloader passes.
However, on big endian, ATAGS_DTB_COMPAT is not supported. And since Kevin has a 1 GB only OpenBlocks, the kernel fails to boot because it believes it has 3 GB of memory, while only 1 GB is actually present.
I believe the most reasonable course of action is to lower the memory size in the DT to 1 GB, to make sure it boots in all cases. What do you think?
Thanks,
Thomas

This sounds like the right approach -- having the DT contain safe defaults and not rely on bootloader (since in this case you can't).

Agreed.
thx,
Jason.

Have not seen it before, but OOM is probably unrelated to irq changes.

The OpenBlocks AX3-4 has a non-DT bootloader. It also comes with 1GB of soldered on RAM, and a DIMM slot for expansion.
Unfortunately, atags_to_fdt() doesn't work in big-endian mode, so we see the following failure when attempting to boot a big-endian kernel:

Fix this by setting a sane default (1 GB) in the dts file.

Kevin,
Please test when you have a moment. If it works for you, feel free to apply it directly wherever you feel it's appropriate.
Yes, this works for me as I've been using the same hack to boot several BE kernels on the openblocks recently.
Could you do the minor changelog update above (ATAG_COMPAT), add the Tested-by and send to arm@kernel.org so it gets tracked for arm-soc merge.
Also, what do you think about backporting this for -stable? At least for v3.14+ since that's when BE started working.
Kevin

Actually, BE started to work in v3.13+.

Also FYI, I put a temporary hack into my automated boot setup to use fdtput to live-patch the openblocks DTB with 1G, and you can see that openblocks is now passing boot test for big-endian:
http://lists.linaro.org/pipermail/kernel-build-reports/2014-June/003812.html
Also FYI, I added mvebu_v7_defconfig + CONFIG_CPU_BIG_ENDIAN=y to the mix, so those should start showing up in subsequent boot tests also.

Great, thanks a lot for working on adding big endian testing to your board farm. This is definitely going to be very useful!
Thanks,
