[Merge] lp:~morphis/goget-ubuntu-touch/add-turbo-bootstrap-support into lp:goget-ubuntu-touch

[Simon Fels]

The proposal to merge lp:~morphis/goget-ubuntu-touch/add-turbo-bootstrap-support into lp:goget-ubuntu-touch has been updated.

Commit Message changed to:

Add bootstrap support for turbo device

The bootloader on turbo does not have support for fastboot format <partition> or fastboot boot <image>. Therefor we have to workaround this by using a OEM specific bootloader command to reboot into recovery and a new command in system-image-upgrader to format the cache partition. The new command "format cache" will do an rm -rf /cache but will exclude all files on /cache/recovery as that is where we store OTA updates, a SWAP file etc.

Adding this new command doesn't cause harm for any other device as the
system-image-upgrader script will just warn for an unknown command but
not fail.

Also this adds an alias for turbo which is named "smdk" from the bootloader which can't be changed anymore on our production devices.
