っローカル設定！LOCAL.CONF！

テンプレートをmeta-debianから持ってくる

$ cp <path to layer>/meta-debian/conf/local.conf.sample conf/local.conf

meta-renesasから、グラフィック・マルチメディア（EVAパッケージ関連）の設定をいただく

$ cat <path to layer>/meta-rcar-gen3/docs/sample/conf/h3ulcb/poky-gcc/mmp/local-wayland.conf

このあたりから後ろをまるっとコピー

    253 # Add systemd configuration
    254 DISTRO_FEATURES_append = " systemd"
    255 VIRTUAL-RUNTIME_init_manager = "systemd"

以下を追記する

# for R-Car Gen3 (H3ULCB)
DISTRO = "deby"

MACHINE = "h3ulcb"
SOC_FAMILY = "r8a7795"

VIRTUAL_KERNEL = "linux-renesas"

# Remove x11 (Not yet tested wayland with x11)
DISTRO_FEATURES_remove = "x11"
IMAGE_INSTALL_remove = "libx11-locale"
