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: | bloat-o-meter2 arch/arc/kernel/setup.o.0 arch/arc/kernel/setup.o.1 | add/remove: 0/0 grow/shrink: 2/1 up/down: 64/-132 (-68) | function old new delta | setup_processor 610 670 +60 | cpuinfo_arc700 76 80 +4 | arc_cpu_mumbojumbo 752 620 -132 Signed-off-by: Vineet Gupta <vgupta@synopsys.com> |
