Revision 73e284d2572581d848267c74552215f95f0f0996 authored by Vineet Gupta on 21 October 2016, 00:49:15 UTC, committed by Vineet Gupta on 28 October 2016, 17:07:43 UTC
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>
