So after talking about it at the last Linaro Connect, I'vefinally gotten around to making a first pass at providing config fragments for the linaro kernel. I'd like to propose merging this for 12.04, and doing so early so we can make sure that all the desired config options are present in the fragments and to allow the vairous linaro build systems to begin migrating their config generation over.
The current tree is here:
http://git.linaro.org/gitweb?p=people/jstultz/android.git%3Ba=shortlog%3Bh=r...
The most relevant commit being:

This includes config fragments for a linaro-base, an android-ization fragment, and board configs for panda, origen and imx53.
I suspect we'll need an ubuntu specific fragment as well as all the other board fragments.
There is likely to be quite a bit of churn as we decide what sort of configs are really common and which are board specific. But that's ok.
Configs are generated from the config fragments, as follows:
./scripts/kconfig/merge_config.sh ./configs/linaro-base.conf ./configs/android.conf ./configs/panda.conf
You may see warnings, which are not fatal, but should be reported so they can be properly cleaned up.
I'm asking for Build folks to take a look at the above and consider how they might merge in fragment assembly into their system replacing their current config generation.
I'd ask Landing teams to take a look at this, and report any missing config options or fragment chunks they'd like to see.
I have updated origen.conf and linaro-base.conf for testing Samsung LT kernel. The results are updated in [1].
I'll take a look at the changes and try to merge them into my tree.
Ok. I've merged most of what you added, but made some tweaks of my own to quiet some of the warnings at merge time.
Let me know if you see anything badly missing. Some of the items I dropped look like they're from feature branches?
Right, some of the config options should better move to the feature branches. I have cleaned up origen.conf so that we can now boot linux-linaro-tracking kernel till the console. Code dropped at [1].
With the help of a couple of patches[2], I was able to get Ubuntu booting up till home screen.
I haven't tested Android though.
Following is the list of added patches. 0b066ba ARM: EXYNOS: Increase DMA pool allocator size for framebuffer This patch is not required if CMA patches are added to the kernel.
fb8fa05 ARM: EXYNOS: Add clkdev lookup entry for lcd clock A rebased version of this patch is queued for 3.4-rc1.
