# This makefile generates the docker files for Yocto builds.
# The containers for the current architecture are the one built using make all.
# To build containers for a different architecture, you need to call make for
# the image you want explicitely.
# The containers are named this way:
# YOCTOVERSION-TARGET for x86_64 hosts
# YOCTOVERSION-TARGET-arm64v8 for arm64 hosts
# For example you can build an arm64 container with the following command:
# make yocto/kirkstone-qemuarm64-arm64v8
# Yocto versions we are currently using.
YOCTO_VERSION = kirkstone
# Yocto BSPs we want to build for.
YOCTO_TARGETS = qemuarm64 qemuarm qemux86-64
# Supported container architectures.
YOCTO_ARCHS = amd64 arm64v8
# Architecture we want to use in gitlab CI (depends on runners arch).
CI_ARCH = arm64v8
define GEN_DOCKER
# Make all is generating architecture we use in the CI.
