Ubuntu Platform Enablement for ARM Fast Models

Registered by Ricardo Salveti

Linaro is now working on supporting ARM Fast Models for early development on models before the silicon is available. This blueprint is to cover the platform enablement that's needed to support the Fast Models as a normal target, including:
 - Getting it to work properly with our images (e.g nano and developer)
 - Setting up the CI kernel builds for the kernel that has the Fast Model support
 - Enabling a kernel package and making it available the same way we're doing with our other kernel flavors
 - Change the linaro-image-tools to make it understand what is a Fast Model, and how to produce a valid image for it (special kernel image with device tree, rootfs image for a virtual sd card, etc)
 - Providing support for both the big.LITTLE and LAVA team, changing and optimizing our images as necessary

The initial targets would be A15, A7, A15/A7 models.

[rsalveti, Mar 28, 2012] The remaining WI can be tracked as a bug, then we can close down the blueprint as it seems we're done with it.
