There are Device Tree (DT) platforms where one kernel fits all devices - like NVidia Tegra for example. So their maintainer can add one entry into flash-kernel database and get work done.
But for other DT platforms is may not be possible. For example on Exynos5 we have Samsung ARM Chromebook and Arndale board. First one uses linux-chromebook 3.4.0 kernel while latter one uses linux-linaro kernel - and each does not support other. They also boot with different bootloaders...
With current code Exynos5 platform does not work cause all flash-kernel knows is "SAMSUNG EXYNOS5 (Flattened Device Tree)" which does not help here.
Attached patch adds support for checking model name present in Device Tree so support for Chromebook can be provided as for "Google Snow" machine.
Status changed to 'Confirmed' because the bug affects multiple users.
