ARC: [kbuild] Retire CONFIG_ARC_CPU_REL_4_10 (742f8af6) · Commits · 戴 / test

Back when ARC700 4.10 was released, the related kernel features were tied to this config item so they could be disabled in one shot (i.e. LLOCK/SCOND, SWAPE, RTSC..) That having happened a while back, all new ARC customers weill get 4.11+ so those features can be assumed to be present and need not be tied to a top-level (we still retain the ability to individually disable them). Further, since ARCv2 also shares some of those feautes, removing it simplifies things a bit in Kconfig Signed-off-by:
