Android on ARM Fast Models

Registered by Zach Pfeffer on 2012-02-29

Fast models help to validate programmer's view model even before the silicon is available. Linaro Android needs to support Arm fast models like Cortext A9,Cortex A15 ,Cortex A7, Cortex A15x1-A7x1 combinations.

We'll:

Run Android on A15 fast model
Run Android on A7 fast model
Run Android on A15/A7 fast model

Notes:
[2012/2/28 pfefferz] Put notes here.
[2012/2/29 vishalbhoj] I could boot landing team's kernel + one patch from Dave's kernel to add support RTSM fastmodels along with tiny_android userspace using NFS (saw some android related logs)but could not get the shell at the end.Need to figure out how to enable CLCD to boot android with full GUI.
[2012/3/1 vishalbhoj] android now boots on fastmodel to console.CLCD driver needs to be fixed to have android boot to GUI.Need to decide if filesystem should reside on NFS or MMC. MMC is currently not working on fastmodel.
[2012/3/5 pfefferz] Make sure we split out FAST_MODEL when it done.
[2012/3/11 mansson] TINY_ANDROID in android-build probably by Wednesday.
[2012/3/14 vishalbhoj] Android builds has been setup at https://android-build.linaro.org/builds/~linaro-android/vexpress-rtsm-ics-gcc46-armlt-stable-open/
[2012/3/21 vishalbhoj] one can ssh with "-X' option into flexlm server and then start the simulator which would get the Fastmodel's window at the local host machine. ARM is internally lookig at the bottlenecks in the Fastmodel's performance.They hope to improve the mmc performance once they move to virtio interface .

Meta:
Roadmap id: ANDROID2012-Q1-FAST-MODEL-PLATFORM
Headline: Android runs on A15, A7 and A15/A7 fast models
Acceptance: Android builds from android-build that run on A15, A7 and A15/A7 fast models and documentation.
