    ARC: boot log: refactor printing abt features not captured in BCRs · 73e284d2
    Vineet Gupta authored
    On older arc700 cores, some of the features configured were not present
    in Build config registers. To print about them at boot, we just use the
    Kconfig option i.e. whether linux is built to use them or not.
    So yes this seems bogus, but what else can be done. Moreover if linux is
    booting with these enabled, then the Kconfig info is a good indicator
    anyways.
    
    Over time these "hacks" accumulated in read_arc_build_cfg_regs() as well
    as arc_cpu_mumbojumbo(). so refactor and move all of those in a single
    place: read_arc_build_cfg_regs(). This causes some code redcution too:
