OSTree-enabled image for raspberry Pi
Bug-AGL: SPEC-254 v2 [jsmoeller]: change rpi fdt addr to 200M (fix cma), re-add inherit gobject-introspection (!) v3 [oytis]: move boot logic to editable uEnv.txt Change-Id: Ic54aadc8377ed1e2a8f2f4ab87db2a7a6660cd15 Signed-off-by: Anton Gerasimov <anton@advancedtelematic.com> Signed-off-by: Jan-Simon Möller <jsmoeller@linuxfoundation.org>
