Bug#631396: flash-kernel: Please add support for Toshiba AC100

[Julian Andres Klode]

Package: flash-kernel
Severity: wishlist

This bug is for adding support for the Toshiba AC100, a
Tegra 2 based notebook, to flash-kernel. The AC100 boots
from an Android boot partition located on its internal
eMMC storage.

I am including the code currently used in the 
“Toshiba Tegra AC100 Hardware enablement” PPA
for Ubuntu, written by Oliver Grawert.

We could in generalise this a bit by replacing
ac100 with android, the code probably works
for multiple other Android devices as well.

A Recommends/Suggests for abootimg would need
to be added as well.
