From a new poky git repo, on the zeus branch.

git clean -dffx
source oe-init-build-env > /dev/null
bitbake-layers layerindex-fetch meta-oe meta-python
bitbake-layers layerindex-fetch -b master meta-arm meta-arm-toolchain
bitbake-layers add-layer ~/yocto/meta-arm/meta-arm-bsp
echo -e '\nDL_DIR ?= "/yocto/downloads"\nBB_GENERATE_MIRROR_TARBALLS = "1"\nSSTATE_DIR ?= "/yocto/sstate-cache"' >> conf/local.conf
echo -e '\nINHERIT += "testimage"' >> conf/local.conf
MACHINE=gem5-arm64 bitbake core-image-sato


I'm running debian-10, which is probably why it was not seen by
others.

Jon
