meta-raspberrypi: AGL support for Raspberry Pi
Yocto/OE layer that extends the recipes for mesa and the supported Linux kernel for Raspberry Pi for successful build of AGL with Wayland, Weston and Qt. It is based on the existing ports of Tizen and GENIVI Development Platform for Raspberry Pi. Change-Id: Icfed9e888c2abaf26c14ab402d0a90215862afbd Signed-off-by: Leon Anavi <leon.anavi@konsulko.com>
