Integrate ARMs DS-5

Registered by Zach Pfeffer on 2011-09-15

There are 3 pieces to this: a ssh server for DS-5 host <-> target communication, gdbserver for application debugging and a
gator daemon and kernel module for system profiling with Streamline

There's a PPA at https://launchpad.net/~linaro-maintainers/+archive/arm-ds5 for the work thats already been done on Ubuntu.

Whiteboard

Headline:
The linaro Android builds has support for ARMs DS-5.

Acceptance:
The ARM landing team has confirmed that DS-5 (gator) works on at least the upstream Panda build and gator is included in all staging builds.

DS-5 5.8 gator daemon and module ( former includes Android.mk ) sources now available under http://git.linaro.org/gitweb?p=arm/ds5/gator.git;a=summary

[patrik-ryd, 2011/10/04] Added work items.
[patrik-ryd, 2011/10/06] builds for panda, still need to verify that I did not break beagle.
[patrik-ryd, 2011/10/07] the panda boots and has gator insmoded and the gatord is running.
[patrik-ryd, 2011/10/07] Pathes sent for review.
[patrik-ryd, 2011/10/10] Need some changes in the gator git to be able to move to the next WI. Waiting on ARM LT.
[patrik-ryd, 2011/10/10] Enabled in daily upstream build.
[patrik-ryd, 2011/10/12] Snowball, Origen & imx53 kernels need to have profiling and tracers enabled (http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.dui0482e/BABECIDJ.html)
[patrik-ryd, 2011/10/12] Adding WI to track progress on configs for different kernels.
[patrik-ryd, 2011/10/18] Waiting for LTs to update configs. Investigating why gator driver is missing on builds on buildserver, but available in local build.
[patrik-ryd, 2011/10/20] Still investigating why gator driver is missing on builds on buildserver, but available in local build.
[fboudra, 2011/10/21] Fix WI: config for Snowball staging build is on hold while we make a new staging kernel.
[patrik-ryd, 2011/10/21] Added a dependency between gator and the other kernel modules to solve the build problem on the server.
[patrik-ryd, 2011/10/26] Verifying that everything actually works is blocked by https://bugs.launchpad.net/linaro-android/+bug/881848
[patrik-ryd, 2011/10/26] The new kernel configs are handled by https://bugs.launchpad.net/linaro-landing-team-samsung/+bug/882053
[mansson 2011-10-28] Still blocked by Kernel Configuration missing. Action to ask Landing Teams to carry these patches in order to speed up the delivery.
[2011-11-17] The gdb problem has be solved and some LTs have provided configs.
[2011-11-22] Only Origen missing support in kernel. Recommend we close this and write a bug for Origen to enable gator in user space when #882053 is set as delivered for Origen.

[2011-11-23 patrik-ryd] Implemented with teh following known bugs...
https://bugs.launchpad.net/linaro-android/+bug/892899 "gatord does not start up in Snowball. Missing gator.ko"
