[2012/8/21 pfefferz] Put notes here please.
[2012/8/22 patrikryd] Moved ongoing wi and todo wi from https://blueprints.launchpad.net/linaro-android/+spec/snowball-jellybean here
[2012/8/23 patrikryd] http://review.android.git.linaro.org/2669 tested. Needs +2 from review.
[2012/8/28 patrikryd] Kernel build problem http://pastebin.ubuntu.com/1171313/
[2012/9/3 patrikryd] Still build problems in kernel. Have asked Kejun to look at it.
[2012/9/6 patrikryd] According to mpoirier DT support is probably missing in LAMC
[2012/9/10 patrikryd] Need to add a few lines in the BoardConfig to build the DT for snowball
[2012/9/10 pfefferz] patrik-ryd to verify "Solve the kernel build problem with mathieu.poirier"
[2012/9/17 patrikryd] The tracking build builds today. Setting Kejun's WI to DONE
[2012/9/17 patrikryd] Sent patches for LAMC and building DT files for review
[2012/9/17 patrikryd] Set BUILD_TINY_ANDROID=true for the tracking build
[2012/9/19 patrikryd] Had to revert my patches for build DT file. Cause problem for stable build.
[2012/9/20 patrikryd] Patches for DT reviewed and merged.
[2012/9/24 patrikryd] mpoirier has figured out why we do not boot to console and will push his patches today.
[2012/9/24 pfefferz] Progress was slowed due to graphics acceleration on Snowball. Bumping to 12.10.
[2012/9/28 patrikryd] Boots to a prompt now if u-boot is updated. Need better instruction on build page.
[2012/10/02 patrikryd] Instructions on https://android-build.linaro.org/builds/~linaro-android/snowball-jb-gcc47-linaro-tracking-open/ updated.
[2012/10/02 patrikryd] created https://bugs.launchpad.net/linaro-android-build-tools/+bug/1060272
[2012/10/02 patrikryd] Proposed https://code.launchpad.net/~patrik-ryd/linaro-android-build-tools/linaro-android-build-tools for merge. Should solve Bug#1060272
[2012/10/12 patrikryd] Boot problem. U-boot wants to open init.st-ericssonu8500platform(device.rc instead of init.calaosystemssnowballplatform.rc
[2012/10/16 patrikryd] http://review.android.git.linaro.org/2903 and http://review.android.git.linaro.org/2904 should solve the current boot problem
[2012/10/17 patrikryd] The new boot problem is that the partition are not mounted. Probably a timing problem.
[2012/10/17 patrikryd] Have tested latest version of LAMC. Bug 1055644 solved. Tested on both snowball builds. Updated instructions on build server (removed mpoiriers work around and said that tracking build needs 12.10 lamc release (even though it does not exist yet :) )).
[2012/10/17 patrikryd] Looked at https://wiki.linaro.org/Platform/DevPlatform/LinuxLinaroKernelTreeProcess trying to figure out if we should use linux-linaro-tracking or linux-linaro branch on the kernel
[2012/10/17 patrikryd] neighter linux-linaro-tracking or linux-linaro branch builds for Snowball Android at the moment since there is no defconfig.
[2012/10/22 pfefferz] WI's related to FB split. See: https://blueprints.launchpad.net/linaro-android/+spec/fb-on-tracking-snowball.
[2012/10/22 pfefferz] Moving to 12.11 since its unclear if android-build based builds boot.
[2012/10/25 patrikryd] Received patches from Ushit. Created a build https://android-build.linaro.org/builds/~patrik-ryd/tracking-fb/. Will try out his patches tomorrow and push them to gerrit of the build is ok.

Headline: Snowball Jellybean boots with a tip kernel
Acceptance: Snowball Jellybean boots with a tip kernel from the STE landing team and keeps booting as development progresses.
