MIPS: loongson64: fix FTLB configuration
It turns out that 'decode_configs' -> 'set_ftlb_enable' is called under c->cputype unset, which leaves FTLB disabled on BOTH 3A2000 and 3A3000 Fix it by calling "decode_configs" after c->cputype is initialized Fixes: da1bd29742b1 ("MIPS: Loongson64: Probe CPU features via CPUCFG") Signed-off-by: Huang Pei <huangpei@loongson.cn> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
