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.
