What about these ones?
git grep 'cpu = ' config/arm | grep -v auto
config/arm/arm64_altra_linux_gcc:cpu = 'armv8.2-a'
config/arm/arm64_ampereone_linux_gcc:cpu = 'armv8.6-a'
config/arm/arm64_bluefield3_linux_gcc:cpu = 'armv8.4-a'
config/arm/arm64_cdx_linux_gcc:cpu = 'armv8-a'
config/arm/arm64_hip10_linux_gcc:cpu = 'armv8-a'
