Normally this is as simple as adding one line to prom_init(): board_ebase_setup = &bmips_ebase_setup; Signed-off-by: Jon Fraser Signed-off-by: Kevin Cernekee --- arch/mips/kernel/smp-bmips.c | 1 + 1 file changed, 1 insertion(+) diff --git a/arch/mips/kernel/smp-bmips.c b/arch/mips/kernel/smp-bmips.c index 8383fa4..887c3ea 100644 --- a/arch/mips/kernel/smp-bmips.c +++ b/arch/mips/kernel/smp-bmips.c @@ -541,6 +541,7 @@ void bmips_ebase_setup(void) &bmips_smp_int_vec, 0x80); __sync(); return; + case CPU_BMIPS3300: case CPU_BMIPS4380: /* * 0x8000_0000: reset/NMI (initially in kseg1) -- 2.1.1
