As far as I understand, the A1 and S4 families are not fully compatible
with the Meson architecture, and we haven't provided additional ARCH_*
for them.
In my opinion, it's a good time to split the Meson architecture into
proper subsets, or rename it treewide (maybe only config option
ARCH_MESON => ARCH_AMLOGIC).
